You can exists without pulseaudio.
So try to uninstall it.

[srikar137]

I un-installed it , but experience with my 5.1 with alsa is quite poor compared to pulse.Pulse is good,But pulse is taking a lot of CPU(i can literally hear CPU fan noise,along with the music i hear .

try this (5.1 howto)

Pulse Audio is a rainbows disaster. Theoretically its cool and it has potential, but leave it to people who need it and know how to trouble shoot it. Its not ready for point and click users.

I would like some instructions for the best way to remove it from Julia please.

Some poor guy thought his CPU was toast and replaced it because of this shit.

I had this happen to me a few times.....

[Nick_Djinn]

This is happening to me 100% of the time lately.

[srikar137]

Lets hope this gets fixed very soon.

And get rid of the Pulse.

The problem has temporarily resolved, but next sign of trouble I wont hesitate to upgrade to a PulseAudio free setup.

Are there some polished alternatives I could add that are more stable besides vanilla ALSA?

I had the same problem. I'm not sure if I fixed it the right way or not.

I was having problems with skype notifications static, sizzling and crackling so I changed a line in /etc/pulse/default.pa:

Code: Select all

load-module module-udev-detect use_ucm=0 

to

Code: Select all

load-module module-udev-detect use_ucm=0 tsched=0

This solved the crackling problem, but created another one. The cpu was running at 24%, and that wasn't going to do at all.

So I just changed the line in /etc/pulse/default.pa to:

Code: Select all

load-module module-udev-detect

Code: Select all

sudo /etc/init.d/pulseaudio force-reload
pulseaudio -k

To further reduce cpu usage you can edit /etc/pulse/daemon.conf:

Code: Select all

high-priority = no
realtime-scheduling = no

Then restart your server again:

Code: Select all

sudo /etc/init.d/pulseaudio force-reload
pulseaudio -k

Using those settings seems to reduce cpu-usage for me drastically. Keep in mind I have no clue what those settings in /etc/pulse/ change. I simply found them on a forum. Just like you are now
