I do not know much about ubuntu/linux, but I have been trying things
blindly for awhile and will only add what has not already been said. I
get huge variations in the quality of sound when I adjust the hardware
profile under sound preferences. The changes range from no sound, to
very tinny sound,
I also have the same crackling sound problem on a Dell Dimension 8100
(Cirrus Logic CS 4614/22/24/30 [CrystalClear SoundFusion Audio
Accelerator]). It started when I upgraded to Karmic, though now I'm
using a fresh install of Maverick. The problem, however, is still there
in Ubuntu 10.10.

THis patch is not in the stable queue, so I am hesitant to pull it into

Like shanen (Shannon Jacobs), sound was working with 9.04 on my IBM T22
with Sound Fusion CS46xx. When I upgraded to 9.10, sound stopped
working. I then upgraded to 10.04, and still no sound. I then loaded the
10.04 live disk and still no sound. Does anyone have a clue what is
wrong or how to fix
Any word? I see that there's no assigned person on this, and the Alsa
folk seem just as reluctant to work on it.

This bug is listed as a duplicate of a different bug report that more

I see is total sound failure (apart from a few intermittent clicks at
boot time) on machines that worked fine with 9.04. That includes three
machines from

The cs46xx driver is notorious for making you jump through mixer
control hoops to do things. We have a FAQ in the ALSA wiki for it.

1. Arch Linux is stuck in Pulseaudio 0.9.15 because of this.
2. CS46xx is buggy as hell. It is possible, but difficult, to trigger the same
bug with plain ALSA. Also, Pulseaudio with ts_sched=1 is unusable with CS46xx.
Audio streams lose their synchronization, and the only way to play audio
When I use my onboard audio instead this problem disappears completely.

Another observation: the volume control on a client (in my case mpd)
does not actually change the volume. There are three states:
volume maxed, sound OK
volume between maxed and minimum, sound distorted at full volume
volume minimized, no sound

OK, I found it. The problem - in my case at least - lies in
svolume_mmx.c (not svolume_sse.c). Reverting that file back to the
previous version gets rid of the problem. These are the changes which
caused the appearance of the distorted sound problem on my box:
diff -pruN
I should add that I run pulseaudio on a Thinkpad T23 with a Pentium
III-m which does NOT support SSE2. As I do not have any systems
available which do support SSE2 I can not test the validity of
svolume_sse.c (which actually contains SSE2 code, not SSE...). Someone
else, like the original bug
knarf, thanks for all your work. Can you give me some help reverting and
testing?
