no sound on macmini G4 on wheezy/sid

[Carl Devos <carl@zongo.be>]

Hello,

Can anybody help me getting sound out of my machine ?

Here is some (hopefully) relevant information.

$ grep machine /proc/cpuinfo

I've tried

$ sudo modprobe snd_aoa

Which gives:

$ lsmod | grep snd
snd_aoa                14960  0
snd_seq                48463  0
snd_timer              20029  1 snd_seq
snd_seq_device          8180  1 snd_seq
snd                    50446  4 
snd_seq_device,snd_timer,snd_seq,snd_aoa
soundcore               7962  1 snd


$ cat /proc/asound/cards
--- no soundcards ---

Same with

sudo modprobe snd-aoa-codec-toonie

(after removing snd_aoa)

Thanks in advance,
