I have a 24" aluminium mac (model iMac9,1) with an nVidia MCP79 audio card. I can get the sound to work, but it's not stable. I can make it degrade into digital static in usually less than 60 seconds by doing the following: 1) Open a terminal window and type: while true; do echo '^G'; sleep 1; done (Where ^G = control-v control-g) 2) Play a youtube video (so the OS must mix two sound sources) 3) Adjust volume up and down I have tried the following: 1) With the stock 2.6.31-20-generic (ubuntu 9.10) kernel (alsa 1.0.20): 1.1) option snd-hda-intel=mb5 1.2) option snd-hda-intel=imac24 1.3) option snd-hda-intel=mac24 1.4) option snd-hda-intel=mbp3 1.5) option snd-hda-intel=mb31 2) Tried 1.* w/ linux-backports-modules-alsa-karmic-generic 3) Tried 1.* w/ alsa-driver-1.0.22.1 compiled from source Is there anything else I can try? All ideas welcomed w/ open arms -- I'm getting desperate.
