Comment (by jeremy@…):

To quote the other bug:

> Consolidating reports from downstream users:
>
> FE configured to use PULSEAUDIO:default
>
> Recorded or Live TV will start out playing correct audio, but seeking
ffw or rwd loses proper audio, getting either white noise static (raw
digital data?) or no sound at all.
>
> To restore proper audio, one of the following must be done:
>
> 1. Select an alternative audio channel and coming back to the default
one
>
> 2. Repeated skipping again or hitting pause will sometimes, eventually,
restore audio
>
> 3. If all else fails, get out of play mode and starting play again

Comment (by Matthew Wire <devel@…>):

Been meaning to report this myself but haven't had the time to
investigate. The same issue has been happening to me for a while now - I
use the ALSA:pulse output as a workaround but this has issues with
stuttering and sync so is not a great workaround!

Currently running 25607 on ubuntu 10.04 64bit with pulseaudio configured
for simultaneous output to both soundcards.

Comment:

Change the default sampling rate of the pulseaudio server from 44.1kHz to
48kHz or change the default resample algorithm.

The issue is in the pulse server

Comment (by anonymous):

Replying to [comment:8 jyavenard]:
> Change the default sampling rate of the pulseaudio server from 44.1kHz
to 48kHz or change the default resample algorithm.

This actually solves the issue in 0.24 (at least for me). There is
somekind of option for this in Advanced Audio options in Mythtv setup, but
haven't tried if it works.

Work-around that I use is to put
default-sample-rate = 48000
in /etc/pulse/daemon.conf. I use mythtv 0.24 on Ubuntu 10.10.

Comment (by pmb@…):

anonymous's work-around didn't work for me, but I went into the
mythfrontend Audio settings, and in "Advanced Audio Setting" i selected
"Override SRC quality" and Sample rate conversion: Disabled.
