We can rule out PulseAudio

In the ongoing saga of my effort to restore audio to MythTV (see threads
entitled "Audio just quit during playback", "Does MythTV user mplayer"
and "Perhaps a reinstall" in this mailing list) I have uninstalled the
alsa plugin for pulse audio. My system has pulseaudio installed and
everything that needs pulseaudio works with it, but pulse has no way to
work with MythTV.

Nevertheless, MythTV still has no audio.

I'm still looking, but I don't recognize any options. Anybody have
something else I can tweak/check/install/uninstall?

Thanks.

Mark

Uninstalling the alsa plugin for pulseaudio makes it less likely to
work, not more. If you want to rule out pulseaudio, uninstall
pulseaudio.

Reading that thread, it's only in relation with mplayer that has a
hard dependency on pulseaudio ; hardly anything to do with mythtv

And for someone to write "If MythTV still doesn't produce any sound, I
think you can safely eliminate Pulse as your current problem." ; has
certainly a lesser idea of what could be wrong than RobertM or any of
the mythtv developers...

Uninstall pulse and try again

Okay, on the assumption that you know more about this than they do, I
removed pulse audio with "rpm -e --nodeps pulseaudio". Results were not
as dire as last time, so I tried watching recorded content in MythTV.
No audio.

I logged out and logged back in noting that other audio plays just fine.
I tried watching recorded content in MythTV. No audio.

I rebooted the system again noting that other audio plays just fine. I
tried watching recorded content in MythTV. No audio.

I checked the audio settings in setup and found them set to defaults
that worked just fine until MythTV stopped playing audio.

No harm, but no progress either.

I am very interested in hearing any other ideas.

What do you mean by "until MythTV stopped playing audio."?
did it used to work and now it doesn't?

What are your audio settings. Also post some logs with -v audio

I don't think you can remove *every* piece of pulse. Somewhere/somewhen,
I saw a comment that alsa now needs the pulseaudio-libs. So I ended up
with the following chunk of script in my 'dependencies' script (the
whole thing is on the wiki...now a little out of date, but not too badly).

This is for FEDORA...but probably only needs some name changes to work
on other distros. So maybe you should try a 'yum install pulse*' and
then run this ( with only the fedora Everything and updates repos
enabled *and no others* (hence the '-y --nogpgcheck'):

echo " ********************************* "
echo " Install alsa audio files"

yum -y --nogpgcheck install alsa-firmware \
alsa-lib alsa-lib-devel alsa-tools \
alsa-tools-firmware alsa-utils alsamixergui
echo ""
echo " ********************************* "
echo ""
echo ""
echo " Now remove pulse audio files mythtv does not need"
echo ""
echo " Do NOT use 'remove pulseaudio*' as this will remove
pulseaudio-libs"
echo " which will kill gdm and other core programs."
echo ""
yum -y remove pulseaudio alsa-plugins-pulseaudio pavucontrol \
pulseaudio-utils gstreamer-plugins-pulse \
pulseaudio-core-libs akode-pulseaudio
echo ""
echo " ********************************* "
rm -rf /etc/pulse
rm -rf /root/.pulse*

I had audio problems after a recent upgrade of my Mythbuntu system. It
was set to use pulseaudio by default and would lose audio on reboot; I
would have to go into the settings to do some tweaks (I can't recall
what I had to do though)

My permanent solution was to set the "Audio Output Device" to "/dev/dsp"
in the "Audio System" page under "Setup > General"

Thanks for the input Alan. I wish I could say that worked for me, but
it didn't.

Keep 'em coming folks.

Okay, the solution to my issue (sort of) was to install XBMC and link
that to the MythTV backend as a video source. I'm reasonably happy with
it so far.
