Alsa (delsi)

[Petr Zapadlo]

Dobry den

pokousim se zprovoznit starsi zvukovku OAk Mozart a nejak se mi nedari. Teda 
vse se zda ze funguje, ale nic nezvuci.
Pokousim se to rozjet pres alsu (driver 0.5.10,lib 0.5.9, util 0.5.9b).
moduly se normalne nalouduji, v amixer odmutuji PCM a zkousim pomoci aplay 
zahrat wav a ten mi napise jen:
 
[root na petrz /root]# aplay -w pokus.wav
Aplay: version 0.5.9b by Jaroslav Kysela <perex na suse.cz>
Using soundcard 'OAK Mozart at 0x530, irq 9, dma 1'
 
A pak se nic nedeje do te doby mez zmacku CTRL-C.
mpg123 dela v podstate totez.

Muze mi nekdo poradit kde je chyba, co zkusit dal?
Pokud  spustim alsamixer a zesilim kanal digital, dostanu strasne skreky.
Zvukovka urcite funguje, protoze za jakychsi podminek se mi podarilo pres 
aplay vyloudit par zvuku, ale netusim jak.

Diky

S pozdravem
