I had an odd experience with ivtv driver setup in kernel 2.6.30.4. This is not using myth but just reading from the capture cards and manual setup using v4l2-ctl and ivtv-tune. The audio on one input of a pvr-500 sounded really horrible, like far away in the background and ringing. I saw on the v4l2-ctl --all output that it said 'Available subchannels: mono lang2', different than all the other inputs saying just mono. Upon capture restart and normal setting up of the card (changing input to input 0 or Tuner 0) it didn't fix it. It did fix it when I ran the command '/opt/ivtv/v4l2-ctl -d /dev/video2 --set-audio-input 0'.
I ran kernel 2.6.29.1 for months without ever seeing this problem, so not sure if it's a very rare fluke or it'll happen more with this newer kernel (which I just started running a few days ago). I guess this is the 'tinny audio bug', although I've never seen this until now, and didn't ever see anyone notice the mono/lang2 oddity either. It happened twice now, and the second time after setting the audio input to 0 on each capture start, so that doesn't fix it for good. The difference between a good input and bad input is the following from the v4l2-ctl --all cmd... Good - Available subchannels: mono Bad + Available subchannels: mono lang2 Thanks, Chris -- Chris Kennedy [email protected] _______________________________________________ ivtv-devel mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-devel
