Bug Description
Binary package hint: pulseaudio
Hi, after new inwstall of Ubuntu Karmic Koala I have noticed several problems with my sound.
First, problem of overmodulated sound (buggy setting in sound - also in pavucontrol) mentioned in:
https:/
Daniel T Chen helped me with setting pulseaudio -k && PULSE_NO_SIMD=1 pulseaudio. But I did not get any explanation, why this is happening. In my opinion, this is major bug, and is still not fixed. Am I being punished for buying 5.1 surround?
My second problem is stuttering of right front and back channel. After setting PULSE_NO_SIMD (my problem No.1) I got all 6 channels stuttering when overcome certain volume level - so I can not use 5.1 at all. Sound is like blinking (flickering - if it was light and not sound:)).
I have tried several modifications in daemon.conf, but no help.
I want to add in previous Ubuntu version everything was OK. When using only 2 channels, sounds and volume control is OK. I am not sure but maybe it's has something to to with my MB Asus SLI A8N Deluxe and it's soundcard.
Has anybody this problems? Thanks.

Hello, thank you for reporting this bug. I would like to clarify one sentence: "I got all 6 channels stuttering when overcome certain volume level". Does this mean that the stuttering starts when you raise the volume to a certain level? I am not sure if I am interprating correctly.
Also, could you please run the following: apport-collect -p alsa-base 490483
This will help to collect current info on your setup.
