Hi,
I posted this error a while ago, but no-one spotted anything obvious. I'm reposting to see if it anyone can throw any light on it.
I've got a PVR-350 + PVR-250 that work most of the time with MythTv 0.16,
Occasionally I get problems with sound. At any point during a recording
I'll suddenly get interference on the sound, like a loud regular click,
this will continue till the end of the recording. Once the problem
corrected itself later in the recording but that's unusual. There
doesn't seem to be anything interesting in the logs at the time it happens. I've made sure that both cards do work (i.e. select each card separately for liveTV in myth)
Anybody got any clues? Is there anything I can do to get more debug data? In particular, what debug info should I turn on ? I tried ivtvctl -D 10, that seemed to make the problem worse, and I did get lots of DeQ from empty list! messages, are they relevant?
the ivtv bit of modules.conf looks like:
alias char-major-81 videodev alias char-major-81-0 ivtv alias char-major-81-1 ivtv alias char-major-61 lirc_i2c
options ivtv ivtv_std=2 ivtv_debug=1
I also tried playing with tda9887=0/1 - didn't seem to do anything..
attached is the /var/log/messages output from ivtv
any help much appreciated. I've got some time to try stuff out, if someone can point me in the right direction...
thanks
Neale.
