Crackling sound when muted

[Chris Moore]

Binary package hint: alsa-utils

I have a new Asus EEE pc 904ha. Whenever I mute the audio, there is a fairly loud crackling sound. This only happens when some application is attempting to play sound, and only when I mute the volume from the icon in the top right corner of the screen (or via gnome-volume-control, which I think is the same thing). I can adjust the volume to almost nothing, so that it effectively seems to be muted, and there is no crackling. I can also mute the volume when no application is trying to play sound and there is no crackling.

from lspci, my audio card appears to be:
00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)

I also ran the alsa-info.sh script:

I have the same problem with a Dell XPS M1530 running the Jaunty release candidate (it happened on Intrepid as well). lspci gives:
00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 02)

I have the same problem on an eee pc 1000 running Jaunty final (netbook remix) with no customizations.

lspci:

00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)

Crackling persists until I take the "LineOut" channel to zero.

Same issue on DELL P490 under Intrepid and now Jaunty . (00:1b.0 Audio device: Intel Corporation 631xESB/632xESB High Definition Audio Controller (rev 09))

Interestingly enough the issue happens when muting PCM source in "HDA Intel(Alsa)". The issue does not happen when muting master volume.
