I cannot unmute the sound on my XP VM. unticking the mute brings only a fraction of a second of audio (although none is playing!). occasionally, un-muting will work for 5 seconds and will mute again by itself. This seems to be related to Windows losing focus. The system is self-muting in conjunction with losing focus. Regardless of this undesired muting, active windows become inactive every 5 seconds or so. This happens even when a single program is running so I cannot tell which program is stealing the focus. I have Intel audio controller and the system says its working fine and up to date. I already used spybot search and destroy but it did not help with the auto mute problem. tried to install a different audio controller but that did not help as well. Any idea how can I troubleshoot this? Thanks Parallels 5 OS 10.6.8
