I have been trying to resolve stuttering issues with sound from hd
recordings (via HDPVR). I recalled reading that PulseAudio (PA)
has been known to cause problems with MythTV, so I uninstalled
it. My sound went away completely. So I reinstalled it and the
sound came back (plus stuttering).<br>
<br>
Consulting a couple of wiki pages about this, I find contradictory
statements. <a moz-do-not-send="true"
class="moz-txt-link-freetext"
href="http://www.mythtv.org/wiki/Configuring_Digital_Sound">http://www.mythtv.org/wiki/Configuring_Digital_Sound</a>
says PA is "not supported by MythTV" and "For MythTV installations
it is advisable to turn off any sound servers that sit on top of
ALSA such as Pulse Audio or the KDE or Gnome sound servers."<br>
<br>
OTOH <a moz-do-not-send="true" class="moz-txt-link-freetext"
href="http://www.mythtv.org/wiki/Installing_MythTV_on_Fedora#Sound_setup">http://www.mythtv.org/wiki/Installing_MythTV_on_Fedora#Sound_setup</a>
says "MythTV does work with Pulseaudio, however, if you wish to
remove it, you can run the following command to revert to using
ALSA only. yum remove alsa-plugins-pulseaudio." When I run that
command, yum says it's available but not installed.<br>
<br>
So my questions are:<br>
<br>
(1) Can MythTV coexist with PA or not? My video playback is
configured to use ALSA:default, but it must be using PA in some
way since uninstalling it broke the sound.<br>
<br>
(2) Could PA be the source of audio stuttering on playback?
Latest description of symptoms is here <b><a

(shortened Gossamer threads url)<br>
<br>
(3) If PA can't coexist with MythTV, what is the proper procedure
for getting rid of it? Per the digital sound wiki, do I also have
to disable the KDE sound server, and if so how is that done?<br>
<br>
Cheers...Steve<br>

I read somewhere that you need to change the pulseaudio sample rate
setting for it to work with mythtv correctly.<br>
I added "default-sample-rate = 48000" to /etc/pulse/daemon.conf and
it has been working for me.<br>
