Hello,

I posted a question on this topic to the user list, but got no response. 
  I just noticed that there was a recent thread on the topic on this 
list.  I would have replied to that thread, but I just joined the list, 
so that wasn't available.

I wonder if some of the guys chatting on the recent thread might be able 
to answer a few questions.

It was noted that using ivtvctl -q0 sometimes cleared up the problem. 
Someone noted that they use a brute force script to do this every 15 
seconds or so.  This technique doesn't work for me because it actually 
seems to randomly *toggle* the state of the problem.  In other words, if 
the problem is NOT occurring, sometimes this command will trigger it. 
So a brute force method may very well turn a "good" recording into a 
"bad" (tinny) one.

Any comments on this?  I'm running ivtv 0.4.2, so if there was a patch 
or a change post 0.4.2 required to use this trick, please let me know.

On a related note, does anyone know of any way, short of listening to 
the recording, to detect the state of the audio?  In other words, this 
problem occurs often (in mythtv) while recording, so I don't know the 
audio is bad until I playback the recording.  I'd like to devise a 
script that pokes the ivtvl -q0 *only* if the audio is in a bad state. 
Any clues on whether this is possible and how to do it?

Another issue for me was that this command would also produce a short 
but noticeable pause or interruption in the audio.  So running it every 
few seconds produced a very noticeable and irritating periodic audio 
dropout.  Is anyone successfully using a brute force script and *not* 
noticing this?

Finally, I wanted to mention that I'm willing to throw some time at this 
if anyone can let me know what kind of data I could provide that might 
help with debugging.  I noticed another recent post by Hans V that he 
was planning to investigate this problem, so I hope this post is timely, 
and that I might be able to help provide clues to diagnosing the problem.

Thanks in advance.

John
