Hello,

My computer has suddenly stopped to play sounds. It is very strange
because:

1) There is the newest audio driver and it is reported to work
properly in device manager (SoundMAX Integrated Digital HD Audio)
2) There are no messages about audio/sound problems in Windows Event
Viewer
3) Control Panel / Sound configuration is avaible - however
a) when I want to play test sound - the error appears (unable to play
test sound)
b) when I want to configure recording settings - the dialog box
freezes (hangs up), and I must kill it in task manager.
4) Mixer tool insystem tray is avaible, but it doesn't play "ding-
dong" sound when changing volume.
5) When I boot computer to use different operating system (Linux Live-
CD) I can play and record sound.

I've already tried following actions:

1) reinstalling audio drivers
2) installing latest upates (Windows Update, HP Upadate) - Including
Vista SP1.
3) monitoring system using sysinternals tools (process monitor)
4) I've even bought external USB sound card - the problem remains.

My computer is hp 6910p laptop, Vista Business 32 bit.

Thank you for any advice or solution!
