    All audio output is very choppy

    All playback audio is very choppy since upgrading from 11.04 to 11.10
    with a lot of squelching noises.

    I used to get this problem from time to time on 11.04 but restating the x server usially fixed it.


    running on 5.1 speakers with hardware set to analouge 5.1 output and analouge sterio input
    Code:
    dasy2k1@dan-ubuntu:~$ aplay -l

    Re: All audio output is very choppy

    Just noticed that when i try to change the hardware setup in sound settings to analogue 5.1 output with analogue stereo input it changes straight back to analogue stereo duplex...

    it also keeps jumping between the analogue output and analogue headphones connector setting

    when a jack is loaded into the front headphone socket everything seems to work as it should. (as soon as you remove it it breaks again)

    i have the following modules loaded in the kernel with repect to sound

    Code:
    dasy2k1@dan-ubuntu:~$ lsmod | grep snd
