alsa-info output

Description of problem:
When playing audio, e.g. a cd through rhythmbox, changing the volume through the gnome-volume-control-applet leads to audible clipping and short breaks in the audio-stream.

Using alsamixer -c0 to change the master volume output has no such effects

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Play audio
2. Change volume in g-v-c => Fail
3. Change volume in alsamixer => Win
Actual results:
Volume change with clipping

Expected results:
Volume change without clipping

Additional info:
alsa-info.txt attached.

Uh? PA and alsamixer actually control the same mixer.

Please try to reproduce this clipping and provide me with a copy of the output of 'ls' in pacmd!
Comment 2 Andreas Thienemann 2009-04-25 11:45:59 EDT
I can reproduce this with any kind of music played through rhythmbox. If using totem or mplayer from rpmfusion the problem does not manifest.

pacmd output is attached.

pacmd ls output
Comment 4 Lennart Poettering 2009-04-26 21:33:43 EDT
Hmm, if you say this is specific to rb, could you please get me that pacmd ls output when rb is running? The dump only shows mplayer as a client.

Comment 6 Lennart Poettering 2009-04-30 15:41:17 EDT
Hmm, that's the output right when the clipping happened?

It looks absolutely correct to me.
Comment 7 Bug Zapper 2009-06-09 10:32:42 EDT
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.
