If I cold boot the machine and ensure no other applications are running (including all the background processes I can identify that might use the audio bus) I don't see any change in behaviour; i.e running winecfg still tells me there are no audio devices present Dunno if "lsof" works on Open Solaris (couldn't get it to work at all on Solaris). If it does, you can find out which apps using sound: Code: lsof /dev/dsp If it doesn't list anything, it might mean "lsof" didn't work or there isn't anything using sound.
