I searched for this error message on the WWW and did get some responses
that this might be related to the ALSA driver. Can you confirm that?
I added the following options to load with the `snd_hda_intel` module.
{{{
$ more /etc/modprobe.d/snd-hda-intel.conf
options snd_hda_intel position_fix=1
}}}
No starting `gnome-volume-manager` does not give a high CPU load anymore
and behaves as expected. The problem now is, when there is high load on
the system as opening an application the audio is not useable anymore
(strange noises instead of music in MPlayer for example) and the
application needs to be restarted.
I also find the following in the output `dmesg`.
{{{

Is that a known problem? Is my only option to report this to the ALSA
guys?

A per symbol breakdown would be good.
With the great help in the #oprofile IRC channel I was told that you maybe
need the output of `oprofile -l`. You can find the full output in
[http://de.pastebin.ca/1759464 pastebin]. Here is an excerpt.

What options do I have to pass to `opreport` to get such a symbol breakdown? I searched for this »oprofile symbol breakdown« and the hits did not contain any information on what options to use. Reading the manual page (`man opreport`) and searching for »symbol« also just brought the `-l` option to my attention. I just read HowToUseOProfile again were it says in step 5 »Generate a per-symbol break down of the profile data:« to use `opreport -l /usr/bin/pulseaudio` whose output I provided in my report. Or did I do anything wrong. I have the package with debug symbols installed (pulseaudio-dbg 0.9.21-1). Could you please point me to some instruction on how to generate the information you need. Thanks to Ford_Perfect on the IRC channel, it was pointed out to me, that there seems to be some problems with the debugging symbols. I try to straighten this out [1] and will submit the OProfile symbol breakdown afterward.

I am able to reproduce this with `pavucontrol` too. I therefore adapted
the summary.

Lower latencies automatically mean higher CPU usage. So, you can expect something like 30% or so in the worst case, which multiplies if you have many cards. -- Ticket URL: http://pulseaudio.org/ticket/758#comment:6 PulseAudio http://pulseaudio.org/ The PulseAudio Sound Server ___ pulseaudio-tickets mailing list pulseaudio-tickets@mail.0pointer.de https://tango.0pointer.de/mailman/listinfo/pulseaudio-tickets
