** Description changed: For a while now on precise I can't watch videos or listen to audio in any app as it's choppy. So audio appears to be at double speed, resulting in the video going at double speed. I have tested in spotify, mplayer, totem, flash (youtube) and they all exhibit the same behaviour. Even the audio test sound thing in control centre 'front left' sounds choppy. Oddly if I record the audio directly from the sound card to a wav file using sox and then play it back on another machine it plays fine. It's just outputting sound to the speakers that this machine appears to have problems with. + **** Current workaround **** + + edit /etc/modprobe.d/alsa-base.conf + and add this row: + options snd-hda-intel position_fix=1 + + reboot your computer for changes to take effect. + + **** + ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: pulseaudio 1:1.1-0ubuntu4 ProcVersionSignature: Ubuntu 3.2.0-7.13-generic 3.2.0-rc7 Uname: Linux 3.2.0-7-generic x86_64 NonfreeKernelModules: nvidia wl AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
