Running XP MCE on an HP DV8000 - a few days ago, I lost my sound (got messages like "there are no active no mixer device available" when I clicked on the speaker volume icon in my system tray). I noticed that upon reboot, the sound DOES function during a part of bootup, but then stops working (i.e. I CAN click on volume icon and get the mixer panel during early part of bootup process, but then 30 seconds later, when I click on it, I get the above error message). I then monitored the Windows Audio Service during reboot (I kept pressing F5 to refresh every 2 seconds) and saw that the Windows Audio service Started, and then before bootup completed, the service STOPPED. I checked the event log, but found no relevant entries. I can start the Windows Audio service manually and that gets me my sound back.
Next step is to mess with msconfig and the startup programs to see if any of them are causing the problem . Also wondering if a HARDWARE problem might cause the service to stop (Device Manager does not show any problems though).
Anyone know what's going on here and how to resolve?
