<p style="margin-bottom: 0cm; margin-top: 0pt;">Hi,</p>
<p style="margin-bottom: 0cm; margin-top: 0pt;"><br>
</p>
<p style="margin-bottom: 0cm; margin-top: 0pt;">Thanks for your answers
(all of you, that is).<br>
</p>
<p style="margin-bottom: 0cm; margin-top: 0pt;"><br>
</p>
<p style="margin-bottom: 0cm; margin-top: 0pt;">It looks like I blamed
pulseaudio, when the problem is really in the ALSA driver. As a matter
of fact, there are several complaints by pulseaudio in the log file
about ALSA misbehaving, and that there is probably a bug in the
snd_hda_intel kernel module, but since ALSA is a good old friend, and
pulseaudio is new and annoying, it's obvious who one should blame.<br>
</p>
<p style="margin-bottom: 0cm; margin-top: 0pt;"><br>
</p>
<p style="margin-bottom: 0cm; margin-top: 0pt;">There is a related bug
report: <a class="moz-txt-link-freetext" href="https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/629339">https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/629339</a></p>
<p style="margin-bottom: 0cm; margin-top: 0pt;">And also some
explanation about the glitch-free (ha!) feature in pulseaudio (the term
coined by Microsoft, just to poke a bit more on pulseaudio):
<a class="moz-txt-link-freetext" href="http://0pointer.de/blog/projects/pulse-glitch-free.html">http://0pointer.de/blog/projects/pulse-glitch-free.html</a></p>
<p style="margin-bottom: 0cm; margin-top: 0pt;"><br>
</p>
<p style="margin-bottom: 0cm; margin-top: 0pt;">I tried the tsched=0
workaround, and it made things just worse.<br>
</p>
<p style="margin-bottom: 0cm; margin-top: 0pt;"><br>
</p>
<p style="margin-bottom: 0cm; margin-top: 0pt;">So the solution is to
upgrade my kernel. Which I shall. But first I have to verify that the
TTY-related bug in 2.6.36 has been fixed so I can log into my computer.<br>
</p>
<p style="margin-bottom: 0cm; margin-top: 0pt;"><br>
</p>
<p style="margin-bottom: 0cm; margin-top: 0pt;">In the meanwhile, I
found "pacmd" which is a swiss-knife general command-line interface for
digging into what pulseaudio is up to. Much of my antagonism vanished
when I found this little utility, as it gives me a chance to debug
things. I don't know how useful it really is, but at least it gives me
an illusion of understanding what's going on. pactl is its little
brother. <br>
</p>
<p style="margin-bottom: 0cm; margin-top: 0pt;"><br>
</p>
<p style="margin-bottom: 0cm; margin-top: 0pt;">Among silly amusements,
one can play samples in the pulseaudio cache. The only sample found on
my computer was the desktop's default bell sound, but hey, I can play
it without Gnome asking for it! Is that exciting or what!</p>
<p style="margin-bottom: 0cm; margin-top: 0pt;"><br>
</p>
<p style="margin-bottom: 0cm; margin-top: 0pt;">As for breaking
dependencies by stealing Fedora-14 RPM and installing them on my FC12
-- surprisingly enough, I installed a bunch of audio-related RPMs with
a simple rpm -i and all the dependencies were OK. The bad news and the
good news are that nothing changed.</p>
<p style="margin-bottom: 0cm; margin-top: 0pt;"><br>
</p>
<p style="margin-bottom: 0cm; margin-top: 0pt;">So I'll bare with these
pulseaudio restarts for a while, and then make my hopefully last kernel
upgrade, and hope everything ticks like a clockwork (am I optimistic or
what?)</p>
