Hello, I recently noticed that my audio device stops working after some minutes and I get the above mentioned error message (and No audio device detected). After restart it works and stops again. Details : Error signature EventType : BEX P1 : svchost.exe P2 : 5.1.2600.2180 P3 : 41107ed6 P4 : netapi32.dll P5 : 5.1.2600.2180 P6 : 411096ac P7 : 0000a3c0 P8 : c0000409 P9 : 00000000 Also there are several files that appear later : \Temp\WER1934.dir00\svchost.exe.mdmp \Temp\WER1934.dir00\appcompat.txt and also 2 text files - appcompat & manifest, which i attached. Im running XP professional SP2 on a Sony Vaio (downgraded from Vista) In Device Manager everything looks fine. Please help me!!!!! Im a musician and this is really terrible. I have run Avast, Ccleaner, Malwarebytes, Superantispyware, none of them find anything. Let me know if you need any other info, I appreciate it!
