[mythtv-users] Occasional missing audio from recordings

[Jelle Kalf]

Same problem here. I have to restart the ivtv module as well.
I've had it once running the ivtv driver for several hours before starting
up the backend drivers.. or not having plugged in my coaxial cable before
loading the driver.
 
Latest issue I had it with was sound going all b0rked when recording channel
Veronica from 20:30-22:15 and then Net5 from 22:15-22:45 ... I think it
didn't like to switch recordings/channels that fast with it's
recordingschedule? I had to reload the driver again.

Hi All,

    I have a Shuttle SB61G2 with a Hauppauge PVR-350 and

    NVidia GeForce 4 440MX for TV-out. I'm using gentoo 1.4

    with a 2.4.21 kernel and the latest IVTV drivers/firmware

    and MythTV 0.12.



    MythTV works wonderfully well on the above setup with

    one remaining issue.



    Occasionally I get no audio on a scheduled recording. This

    has been the case on MythTV 0.11 and 0.12. Most of

    the time the loss of audio on a scheduled recording causes

    live TV to also lose audio, however this is not always the

    case. Sometimes the loss of audio is limited to the

    one scheduled recording, subsequent recordings being

    fine and live tv unaffected.



    If I lose audio on live tv I can fix it by killing mythbackend

    and restarting it. This always fixes the problem... which indicates

    that the IVTV driver has no problem re-initialising.



    I had thought this might be due to some KDE app holding

    open the dsp device but I've disabled all arts binaries

    by making them non-executable. I've also tried running

    under twm, but all to no avail. There's nothing in the

    mythbackend logs to indicate a problem.



    I haven't seen anyone else mention this problem on the

    list so I'm stumped.



    I do get about less than a second of white noise at

    the start of playback on these "no audio" recordings.



    Any ideas much appreciated...



    Doug



    

It happens, although I've never seen it happen during live tv.  I

believe it's an ivtv problem, just waiting for the newest driver to come

out and see if that fixes it.

Restarting the backend doesn't do it for me, I have to do a "modprobe -r
ivtv/modprobe ivtv" before I get my sound back.
But I agree with jose that it is most likely an ivtv problem, they've been
very busy lately and there are several known problems with the current
version in CVS.
