[Win 7 32bit] Weird hangups usually when playing sounds
Hi,
Ok so the problem is as follows. Sometimes when I play sounds on computer (can be msn,video/audio, software, youtube) the computer slowly creeps towards a freeze.
Sometimes the sound starts crackling and sometimes the sound keeps playing uninterrupted (say I have a song playing, it might just play normally while everything else freezes or it might start stuttering/crackling).
During these freezes HD is usually idle/doing whatever it was doing before this happened. The mouse pointer moves around the screen as if nothing has happened. CPU is usually at 100%. There is not 1 specific program that hogs all CPU power but svchost.exe's instance dcomlaunch and its service PlugPlay (Plug and play) tops the CPU chart every single time. Usually audiodg.exe is somewhere at the top too.
If I keep booting and trying sounds until it doesnt freeze the computer will not freeze until I hibernate/shut down the computer. These unaffected boots happen totally random.
I have tried updating sound drivers (my laptop has the AC'97) but that seems to do no good. Also I have uninstalled my antivir as I thought it might have something to do with it but it seems like it didnt.
I have disabled enhancements for my playback device and that didnt help the problem at all.
If you have an idea what could be causing this please speak up!
E: The laptop is a Sony sz61xn/c
Did some quick google and the soundchip might be a SigmaTel STAC9872AK
