Hi, Welcome to Microsoft answers forum. You can check for the sound drivers,whether they are installed correctly. if not uninstall them and install again. I suggest you to verify that the default sound device is set correctly Click Start,type Sound in the Start Search box. Click Sound in the search results at the top of the Start menu. Click the Playback tab. Notice the check mark next to the default device. For most users,the default device is Speakers. Make sure that your audio settings are configured as expected. Follow these steps: On the Playback tab, select the playback device, click Properties, click the Advanced tab, and make sure that the Default Format is set to the value that you expect. When you finish, close this window to return to the previous window. On the Playback tab, select the playback device, click Configure, and then make sure the configurations are set correctly. If the sound settings are set correctly, you are using speakers as the sound device, and your speakers are already set as the default device, go to method 5 now. Select the sound device that you want as the default sound device, and then click Set Default. Click OK to save your settings and to close the Sound dialog box. Determine whether you can now hear sound. If you can hear sound, the issue is resolved. If you cannot hear sound, try method 5. http://support.microsoft.com/kb/948481 you can also check performing clean boot.

This happens on my system too. I've got an M-Audio Audiophile 2496 and it's worked flawlessly across many upgrades, and on Windows 7 64-bit as well. When the sound cuts out, what fixes the problem for me without requiring a reboot is to open the Sound configuration in Control Panel, disabling the device, and then enabling it. It seems to reinitialize the device and I can go about my business. With so many different system configurations having this kind of problem, this definitely has to do with some sound subsystem in Windows 7, as I've never had this problem in other Windows OSes with the same hardware. Anyway, until Microsoft fixes the problem, try disabling/enabling the sound device to get it functioning again.

Same problem here. Creative speakers/mic etc. I took the lot out and put a cheap pair of headphones/mic combination and went to SKYPE. No problems. I then tried VOIP - again no problems. I left the computer on standby during lunch after which neither SKYPE nor VOIP worked. As these are cheapo headphones and don't have software to upgrade, THE PROBLEM MUST BE WITH WINDOWS 7.

I also starting having this problem only after upgrading to Windows 7. This doesn't seem like a driver problem to me either. I have two different sound drivers, one for built in laptop speaker and one for sound jack on docking station. When the sound dies, they both die. If sound is playing, and it is disrupted for some reason, Windows just seems to forget to make sound. I always have to reboot, and rebooting works every time. I have a streaming audio site I listen to a lot, and that sometimes hiccups and gets stuck buffering. That will cause the sound to die. But other things will do the same; youtube for instance. If the playback is paused or disrupted, the sound dies. If the playback keeps going, there's no problem. If the playback ends normally, that doesn't seem to cause a problem either. I think the problems I've had are while using flash-based internet players, but I couldn't swear that's 100%. I have not tried the workaround to uninstall itunes/quicktime. I also use itunes quite a lot and really want to avoid that.

This is not a sound driver problem. This is something with Windows 7 or how W7 interacts with other software. The sound is JUST FINE for a period of time (long or short), then it dies. And a re-boot brings it back. For me, when the sound dies, two different audio drivers both go dead. For me, the cause is reproducible when playing music and it pauses or is disrupted. The sound goes dead every time.
