Hi Alexander

in fact no sound nor internal hp, nor from line out/(digital output).
with your hint, the only change is, pcm2 disappeared.
and stillno sound at all.

some pecisions:
hardware: macmini (intel core duo) built on 6-2009 with:
line in
line out/phone.

i observe this behavior on a macpro and even on a macbook air too:
i mean no sound at all.

with an external amplification i can hear very low signal:
(perhaps a crosstalk)?

i can not say anything about input as the output is not working.
 
in other hand, The snd_hda man page does not say the meaning of
the association numbers 1-14, there is only 0 -> disabled, and
15 -> unassociated???

can you tell me what they represent, and if you have time,
add some words on the man page?

many thanks for your help.
