Xendesktop vista sound

Help - this just appeared today. I tried your solution, it did not fix the problem. Any other ideas? Thursday, November 19, PM. This one did not work for me. I got error: Driver Installation failed: Could not find the media device for this driver.

I have been reading I have re-booted.. I still have no sound! If someone has an answer.. Friday, November 20, AM. If so, I posted my fix on October 1st. It's a drastic measure, and I'd prefer you tried everything else before you take a screwdriver to your laptop, but if you really want your sound fixed and have no where else to turn and no warranty or anything that would be voided by operating on your laptop , it might be worth a try.

I was too scared to do it myself, so I had my boyfriend do it. He just followed the instructions he found online on how to take apart my model of computer, and the sound has been fine since. Neither of us are hardware savvy and we were able to baby-step through the manual re-installation of the sound card. I never let my computer sleep or hibernate anymore. If it needs to be transported without power for a while, it gets shut down and rebooted when I find a plug-in to charge it. The problem has not come back.

Best of luck--I hope you check back to see this. Friday, November 20, PM. For all posters who can no longer see "Sound, video and game controllers" in your Device Manage, this may be the solution you are looking for! Right-click High Definition Audio Or anything else "audio" depending on your computer.

I hope this works because I know first hand that this problem is extremely frustrating to say the least! Saturday, November 21, AM. Saturday, November 21, PM. Sunday, November 22, PM. Belev Thank you very much for your help. I saved all my programs.. Its the sound card itself.

When all the "fixs" here have not worked.. I also checked the HP web site.. Friday, December 4, PM. I simply plugged in my headphones in the headphone slot and the red x went away and once I removed my headphones the sound was up and running again :.

Saturday, December 5, PM. I did exactly that and it didnt do anything?? I did it right too and checked everything and everything says "unplugged".

It doesnt give me an option of enabling or plugging. Sunday, December 27, PM. At first I thought it was only me, but what a surprise. I've had this problem since Christmas. Here's what I did: 1. Downloaded audio drivers around the internet from Intel, Realtek, etc.

Result: still no sound 3. Even updated my BIOS. Result: still nothing so, I wouldn't have known what my on board audio card was if it wasn't for the Intel cd since device manager is not showing sound, video and game controllers. It installed the files and after that "The software for this device is now installed but may not work correctly", then "Code The device cannot start"! And why is my on-board audio not detected in Device Manager?

Sounds really strange I'm out of ideas, please help, anyone Thursday, December 31, PM. I tried this and there was no change.

I've tried every hint I have come across on the web and still nothing. No sound at all. It's getting so annoying! It all happened when I installed some Netgear products to set up my new internet service a few weeks back, though perhaps that was not related at all, just coincidence.

Please, someone help! Hi manong, Wow. I didn't do as extensive a job as you trying to fix my problem the same problem as yours at the start of your post You could try that if you're not too worried about your surgical prowess--it's probably a lot easier to do this on a desktop machine than it was on my laptop. Good luck. Love to hear back from you if you try it. Only problem with me is, mine is not a laptop, and my audio card is on-board the motherboard.

Can it be removed from the motherboard? And i don't wanna tinker with that, I might destroy the whole thing! What I find really strange here, and I will repeat. Here's what I did the last couple of days: I thought, hey, maybe I should buy an external sound card, that should solve it. So I did but couldn't buy a high-end one because most computer shops i visited here in the philippines say they don't sell high-end sound cards anymore I don't know why.

I was so excited, next thing i did was try it. It just sticks! I can't even press Ctrl-Alt-Del. I had to take it off cause I can't use my computer. So here I am again It's just so frustrating right now.

Im totally pissed. Friday, January 1, PM. Hey Stimps I have a HP, and this solution works It seems like I can always rely on solutions online for my pc, since I'm not comp-savvy Saturday, January 2, AM.

Hello people! Here I am again. And I am very proud to say that I've finally solved the freaking thing that's bugging me since Christmas. Wow, I have got to get this nightmare out of my head, maybe I'll scream one time for all my frustration. So, here's what I did: There's this forum I stumbled into that says to download a Windows Update called KB and I did download it with the same result: no audio. Thank God. I never want to experience that nightmare ever again Sunday, January 3, AM.

I have a Toshiba U and i tried everything metioned above, but when i tried what bdock advised it worked. It took me 2 restarts but i finanlly got my sound back after nearly a month. As soon as i got it back i made sure i update the driver by using the device manager as a precautionary measure.

I will let everyone know how things are going. Monday, January 4, AM. This all happened after installing windows package 1. There must be a solution if so many people have had this problem. Thursday, January 7, AM. Did not work. Thursday, January 7, PM. Hi It seems my problem with this audio output device that is not installed goes a little further.

Write down description make and model - double click on it - drivers tab - write down version. NOTE : Sound drivers often rollback so check the version after installation and the reboot to see if the version you installed is there, if not repeat the install - reboot until it is. It can take several tries depending on how many rollbacks it does. Then do same for Device Maker's site.

Highlight speaker and on the lower Right click Properties check settings for Device Usage enabled and so on. Also do same for Configure on Lower Left of that box.

Hi again Shallah and everyone, Well, here's an update on the situation with my computer and the sound. Here is the message that came up: modem device on high defiition audio bus This is the hardware it said it was trying to install.

Tuesday, May 4, PM. Thursday, May 6, PM. Sound files and settings that become changed can cause sound problems. Restore the audio driver to reset audio settings for the sound hardware and reinitialize the sound configuration in Windows. NOTE: If the computer was upgraded to Windows Vista before being upgraded to Windows 7, you might not be able to use all the features of an integrated audio device that is compliant with Audio Codex '97 AC '97 specifications.

To resolve this, update the audio driver. See Step 8: Update the audio driver. Use the driver recovery process to restore audio drivers for the original sound hardware using the following steps:.

On the Hardware Driver Reinstallation welcome screen, click Next. Select the audio driver to reinstall, and then click Next.

Helpful information will advise you how to install drivers using the Windows Device Manager. Follow the onscreen instructions. The Recovery Manager begins reinstalling the chosen driver. After the driver installation is complete, click Finish to restart the computer. After restarting the computer, test for sound. If there is still no sound, continue to Step 8: Update the audio driver. Friday, May 7, AM.

Saturday, May 8, PM. This did not work. Well let me begin. I had purchased Windows 7, no audio device. I purchased Windows 7 Upgrade, no audio device. I was tired of it all now I have purchased a new laptop and all is fine. But I decided why not, and went back to my previous laptop and had installed Office Home and Student Still no audio device.

Wednesday, May 12, PM. Driver installation failed. I guess nothing will work. I had purchased a new laptop, and I am just trying to get this old one working. It was built for Windows XP. No Audio Device no matter what I do to it? Thank you though.

Sunday, May 16, AM. After many hours not reading an answer, here's the solution that worked for me I rebooted and went into setup, opted to reset to default settings, saved the changes and Hey Presto!!

This fix addresses an issue that can cause the audio service CtxAudioService. Attempts to reconnect to an HDX 3D Pro enabled session can fail and users are presented with a black screen. Important : Before applying this fix on a client device, see Knowledge Center article CTX for important information about how the Dynamic Blacklist feature might affect client-side Flash redirection.

Server-side content fetching can exhibit poor performance in restrictive WAN conditions due to the lack of flow control in the Flash Virtual Channel. This fix corrects the flow control for the Flash Virtual Channel and provides smooth playback of Flash objects. To enable this fix in its entirety, you must install both a client hotfix that contains Fix LA and:. With server-side content fetching enabled, Flash content can take unexpectedly long up to six minutes to start rendering in the session.

Specifically, when an email message in published Outlook contains two links, clicking the first link launches Internet Explorer as expected, but the other link fails to open. Note : This fix also requires the corresponding language code pages to be installed on both the client and the server. The code pages are installed by default by the Windows operating system. For example, the Japanese distribution of Windows 7 installs the Japanese code pages by default. However, if you are using a URL with Japanese characters on an English distribution of Windows 7, the Japanese code pages must be installed explicitly.

This applies to both the client and the server because the URLs are transferred from the client to the server when server-side content fetching is enabled.

The issue occurs when the short path expansion is disabled on the server, which prevents hdxflashhook. After installing the latest version of Adobe Flash Player and attempting to play Flash videos, Internet Explorer might incorrectly display the following error message even if the correct version is installed:.

The Citrix audio DMO filter currently does not support audio format conversion and prevents some applications from converting audio formats correctly. This fix introduces a registry key that lets you disable the Citrix audio DMO filter for a list of applications you specify:. When connecting to a VDA, multimedia redirected audio can fail for certain thin clients. This issue occurs with those thin clients that lack a head-end mixer for the audio subsystem. This, in turn, can prohibit access to the audio device by multimedia redirection.

This fix corrects the issue for VDAs running on non-Windows XP operating systems by suppressing automatic opening of the playback device. This fix addresses an issue than can cause the video portion of a multimedia file to trail the audio portion slightly when rendering. When reconnecting to a virtual desktop session, any USB optical drives attached to the endpoint are mapped into the reconnected session.

This happens if optical drives are permitted in the file redirection policies but USB redirection is disabled. Attempts to connect to a Virtual Desktop Agent can fail and the following error message appears: "Error: You are not permitted to restart any more sessions for this resource.

In that case, a race condition can prevent attempts to connect to the agent remotely. If a smart card is present in the card reader at the client device, the smart card PIN prompt can fail to appear. The issue occurs when a legal notice banner is configured and the user does not dismiss accept the notice within four seconds of its appearance.

In such scenarios, the PIN prompt does not appear as the wait for the smart card event times out. This fix introduces support for the following registry key to extend the amount of time, in seconds, before a timeout on the smart card event occurs:. With the above registry key set, the application launches properly if the user dismisses the interactive logon message within 40 seconds; otherwise the application exits after providing the smart card PIN.

To prevent this and give users up to seconds to respond to the PIN prompt, additionally set the following registry key:. This enhancement to Remote PC ensures that the smart card credentials tile rather than the LDAP credentials tile is selected by default when logging on a to a remote PC using a smart card for authentication.

After the installation this enhancement is enabled by default. To disable it, you must set the following registry key:. This fix addresses a weakness in the XenDesktop product. This issue occurs on agents running on Windows 7 and Windows Vista. Please select a valid time zone using the link below. As a result, there might not be sufficient time for any logoff scripts to run and finish. After applying this fix, when a user logs off a session, a pooled desktop waits for the time interval specified in the LogoffActionDelay setting and then restarts.

The default wait interval is seconds 7 minutes. To change this value, add the following entry to the [appSettings] section of the CdsPoolMgr. When reconnecting to a disconnected session, previously visible mapped network drives are no longer visible in Windows Explorer. The Dependencies tab of the Citrix Desktop Service Properties Local Computer window lists four system component dependencies, including a Server component dependency.

The Server component dependency is present in error. This fix removes the inaccurate Server listing. When launching an application from a client mapped drive, the application can launch successfully, but fail to have network connectivity. When reconnecting to a disconnected virtual desktop session, a hidden window created by Adobe Reader might be displayed as a blank window. Attempts to connect to Version 4 of the VDA running on Windows XP might fail during the logon process, displaying only the desktop screen.

Sessions can disconnect unexpectedly, and the disconnect is incorrectly reported as an SSL error on the client, server, or the Secure Gateway. Clicking a published desktop icon multiple times in rapid succession on the Web Interface can eventually cause the launch of the desktop to fail.

Also, the session window might revert to the size of the previous connection rather than being full-screen. Following a ticket validation failure, a pooled VDA running on Windows 7 might become inaccessible until the agent is restarted. When disconnecting from a multiple monitor Remote PC VDA, the resolution on all monitors attached to that VDA decreases to the largest resolution supported by the lowest-capacity monitor.

For example: If Monitor 1 is set to x and Monitor 2 to x, both monitors display at a resolution of x after disconnecting from the session. Attempts to reconnect to a disconnected session can fail. The issue occurs in cases where the PicaSessionMgr. When reconnecting to a disconnected virtual desktop session, dialog boxes might disappear while the associated parent window is minimized.

Seeking forward or backward in Windows Media Player can cause a black rectangle to appear in place of the video. When launching a session immediately after disconnecting from a VM hosted app, the session might start and then log off shortly thereafter. When using smart card authentication, sites in the Intranet zone do not prompt for credentials and fail to load if protected mode is enabled for the Intranet zone. To enable this capability, you must set the following registry key:.

HDX MediaStream Flash redirection does not work for any site when the "Flash URL compatibility list" policy is enabled and a site is added to the list - regardless whether it specified to render on the server, on the client, or to be blocked.

This strategy ensures that you can deliver a full range of multimedia formats, with a great user experience, while maximizing server scalability to reduce cost-per-user.

With server-rendered multimedia delivery, audio and video content is decoded and rendered on the XenApp or XenDesktop server by the application. The content is then compressed and delivered over the ICA protocol to the Citrix Receiver on the user device. This method provides the highest rate of compatibility with various applications and media formats.

Because video processing is compute-intensive, server-rendered multimedia delivery benefits greatly from onboard hardware acceleration. Because most servers do not offer hardware acceleration for video compression, server scalability is negatively impacted if all video processing is done on the server CPU. To maintain high server scalability, many multimedia formats can be redirected to the user device for local rendering. Windows Media redirection offloads the server for a wide variety of media formats typically associated with the Windows Media Player.

Flash redirection redirects Adobe Flash video content to a Flash player running locally on the user device. HTML5 video has become popular, and Citrix introduced a redirection technology for this type of content. Also, you can apply the general contact redirection technologies Host-to-client redirection and Local App Access to multimedia content. Thinwire and Audio virtual channels handle this approach.

The advantage of this approach is that it reduces the hardware and software requirements for the clients. Using this approach the decoding happens on the server and it works for a wider variety of devices and formats. This approach relies on being able to intercept the media content before it is decoded and presented to the audio or display device. This advantage of this approach is that the decoding and presentation is offloaded to the client devices, saving CPU cycles on the server.

However, it also introduces some additional hardware and software requirements for the client. The client must be able to decode each format that it might receive. This approach relies on being able to intercept the URL of the media content before it is fetched from the source.

The URL is sent to the client where the media content is fetched, decoded, and presented locally. This approach is conceptually simple. Its advantage is that it saves both CPU cycles on the server and bandwidth because only control commands are sent from the server. However, the media content is not always accessible to the clients. Desktop operating systems Windows, Mac OS X, and Linux provide multimedia frameworks that enable the faster and easier development of multimedia applications.

This table lists some of the more popular multimedia frameworks. Each framework divides media processing into several stages and uses a pipelined-based architecture.
