Public bug reported: Card type/model : nVidia Corporation MCP79 High Definition Audio (rev b1) found on MacBook Pro 5,5 (and other similar series)
Until kernel 2.6.31-19, the sound works well when compiling alsa-driver from snapshot. Following insctructions found on this page for example : https://help.ubuntu.com/community/MacBookPro5-3/Karmic#Sound Since 2.6.31-20 update, the sound card is not recognized at all. After the update, I did remove : sudo rm -rf /lib/modules/2.6.31-20/kernel/sound and reinstall the linux headers sudo aptitude reinstall linux-headers-2.6.31-20 linux-image-2.6.31-20 Then rebooted and recompiled the alsa-driver (from snapshot). No sound. Issuing the alsamixer command returns that : No mixer elems found. Everything is empty in every alsa cli or gui, just as if I had removed the audio card. Booting back in 2.6.31-29, sounds works well.
