|Running Vista on a Asus P5B Deluxe mb with SoundMAX sound.|
Spontaneously this machine has started to effectively mute itself intermittently for 1 to 10 seconds at a time. (Sometimes until the tune on vlc is stopped and started.)
Both recording and playback are effected. Tried downloading newest drivers and popped in ubuntu 10.04 on live CD and that works perfectly.
The machine still shows the VU meters moving and video is uneffected. Checked mute key on keyboard wasn't stuck down and tried unmuting and changing volume while it was quiet to no effect.
Multiple software and games all tested - all are effected.
All connections into and out of the pc checked and rechecked with different components.
This is a mature Vista install which has been running happily for years.
Other than a full re-install any ideas? :)
