OK, I did some testing. Don't know if it will help, but here are the
results: Do the following to fail the sound - Start at channel 2 - Press Up arrow on remote control, repeat until sound gets noisy, repeat until it clears up. Here's the pattern of works vs. failed (read as three channel changes worked, one failed, seventeen worked, one failed, etc) 3-1-17-1-7-1-11-1-5-1-1-1-11 or, Do the following to fail the sound - Start at channel 2 - Press "Menu" to access on-screen menu, press "down arrow" to move to the next channel, press "OK" to select new channel. Repeat until sound gets noisy, repeat until it clears up. Here's the pattern of works vs. failed (read as eleven channel changes worked, one failed, two worked, one failed, etc) 11-2-2-1-8-1-3-1-12-1-19-1-2 # ivtvctl -d /dev/video0 -q 1 - turns the sound off - I assume it set the audio to a different channel # ivtvctl -d /dev/video0 -q 0 - restores the sound If I put the sound into a failed state # ivtvctl -d /dev/video0 -q 0 - fixes the sound # ivtvctl -d /dev/video0 -q 0 - breaks the sound # ivtvctl -d /dev/video0 -q 0 - fixes the sound If I put the sound into a failed state, repeating this line over and over... # ivtvctl -d /dev/video0 -q 0 - usually fixes the sound on the first attempt - sometimes requires two attempts to fix - asserting this line seems to fail and fix with the same pattern as the failures from above Hope this helps, Don Don wrote:
