Description
I have a MythTV system with three tuners: one PVR-350 and one two-tuner PVR-500. Occasionally, this system gets into a state where all recordings on a given tuner stop having sound. When this happens, mythbackend puts out error messages like this into the log file:
2009-07-09 21:00:32.086 AFD: Opened codec 0xa1b1d00, id(MPEG2VIDEO) type(Video) 2009-07-09 21:00:32.112 NVP: Disabling Audio, params(-1,-1,-1) 2009-07-09 21:00:32.115 NVP: Disabling Audio, params(0,-1,-1)
For lack of a better solution, I usually end up just rebooting the box to make the problem go away, and then deleting the bad recordings and telling them to re-record. However, I'd really like to see this problem stop.

Josh, when you play those files in another video player, mplayer, vlc, etc. do you have sound then? In that case we'll need a short sample of the file (15 sec, you can use top to lop it off).

No, I don't have sound when I play the files in mplayer either. As far as I can tell from the output of mplayer, the files don't have an audio stream at all.
I can get you a sample later today. What do you mean by "use top to lop it off" though?

I've attached a sample of a recording with no sound, and a sample of a recording *with* sound from later that evening after having rebooted the MythTV box.
I had to truncate both samples to 256kB to fit Trac's attachment size limit. If you need more of the files than that, please let me know and I can send them to you some other way.
Thanks for looking into this.

While this still represents an issue that ought to get fixed, I replaced the PVR-350 with a PVR-500 and I haven't had a problem since. Thus, I can no longer reproduce this problem.

Suspect the original issue was driver related, but since the original reporter no longer has the hardware, the bug was opened against an old version and we've no additional reports I'm closing as invalid.
