Since upgrading from Vista to Win7, my microphone input has a delay of 500ms to 1s when recording.  This is most notable in apps like Ventrilo.  Anyone else having this problem?

Windows 7 Home Premium 64bit

HTOmega Claro+ sound card

E6600 Intel CPU

6 gigs of RAM

Nvidia GTX 280 video card

Windows for home | Previous Windows versions | Music, photos, and video

Hi Everyone,

Please see my earlier replies. No functionality has been removed in Windows 7. If you have an audio driver and codec that exposes the hardware loopback, it will still be present on the Levels tab of the Speakers device. However, not all drivers expose this. If you had this option on XP and load the same audio driver, it should be exposed on Windows 7. Same with the stereo mixer. If the audio driver exposes it, it will be available. It is hidden by default on Vista/Windows 7. But on the Recording tab if you right click in the open area and select show disabled devices, you can enable it. If a Stereo Mix device is not shown, then the audio driver is not exposing one. If you had this option on XP, then please try installing the same driver version that was previously installed.

Thanks,

Chris

    Thank you, SpitsBeat, I'm glad I could help :)

    I've been clueless for a while having the same problem until I installed the PCI C-Media sound card. As W7 can't even smell it and everything should be configured thru its own audio manager (Xear3D), I thought that probably would be the same for any other sound card, trying to avoid the bundled W7 audio manager and working only with the sound card own software. A bit tricky and exasperating since most of the people isn't used to tweak around settings and stuff.

    Anyway, from my little understanding, there's still an issue there to be fixed by Microsoft, the one using a mic or line in device thru USB, because the only way the sound card will recognize it is checking the "listen to this device" box. I have a small usb mic splitter so I could use two mics (for a karaoke home system with my pc) but I get about 100-200ms lag, so it's useless.

    @tricky2k:

    Thanks for the link! The folder was there, however empty. I guess the realtek driver update from the realtek site uninstalled the manager or something, I've had the audio manager before the update. But it's back now using the download link you've provided :)

    I've also manage to reconfigure the manager, and my nightmare is finally over! Enjoying the instant playback now, haha. Thank you very much tricky2k, Microsoft needs people like you. ;)

    Cheers.

    @Chris:

    I really appreciate your effort, taking the time off the busy Microsoft work schedule to attend to this issue. Nevertheless, hope that Microsoft could provide an easier alternative -- i.e. a patch -- to fix this issue for other Win7 users.

    Thank you.

    Hi SpitsBeat

    Open a explorer window and go to c:\Program Files\Realtek\Audio\HDA\ . If the drivers are installed, you should have that folder. Then, double click on ravcpl64.exe to open the Realtek audio manager. The audio manager window will popup. If not, look in the systray for a red speaker icon, that's the manager.

    If the folder is not there, or that particular file, pretty strange, you should have to reinstall the drivers again, uninstalling the old ones first. Go here http://www.softwarepatch.com/utilities/hdvista-security-dl.html for the drivers and execute the installer, do not install the drivers from the device manager.

    Did you run the Realtek driver setup, or did you install the driver manually from device manager? Their control panel is called rthdvcpl.exe, or ravcpl64.exe on X64. It's a part of the regular driver package.

    Please also paste the latest dxdiag log with just the audio info.

    Thanks,

    Chris [MSFT]
