The "hardware information" phrase is a bit ambiguous. If you will specify it more precisely you will probably get better answers. – whitequark – 2010-08-14T03:27:24.180

1No need for sudo on Ubuntu, just checked that on fresh 10.04 install. It's better not to use sudo when you're not required to do it just because it lowers your chances to accidentally run something destructive. – whitequark – 2010-08-14T03:24:45.037

@whitequark - True, I corrected that. – laurent – 2010-08-14T21:28:28.343

cat /proc/asound/card*/codec*

cat: /proc/asound/card0/codec97#0: Is a directory – whitequark – 2010-08-14T03:23:40.293

Oh now that's interesting. Usually it's a text file with a full codec dump for the device. So what files are in the directory? – maco – 2010-08-14T04:25:41.163

ok then, try /proc/asound/card0/codec97#0/ac97#0-0 – maco – 2010-08-15T07:04:49.463
