[ALSA] Jest dźwięk, nie ma sterowania głośnością

Cześć,

Mam problem z dźwiękiem poprzez ALSA. Sam dźwięk jest, odtwarzam muzykę przez MPD, jednak za żadne skarby nie jestem w stanie sterować głośnością. W /dev/sndstat mam linię "Mixers: NOT ENABLED IN CONFIG", stąd zapewne przyczyna problemów.

Kod:

pawel@hermony:~$ cat /dev/sndstat 
Sound Driver:3.8.1a-980706 (ALSA v1.0.21 emulation code)
Kernel: Linux hermony 2.6.32-5-amd64 #1 SMP Wed May 18 23:13:22 UTC 2011 x86_64
Config options: 0

Installed drivers: 
Type 10: ALSA emulation

Card config: 
HDA ATI SB at 0xfe7f4000 irq 16
HDA ATI HDMI at 0xfe9e8000 irq 19

Audio devices: NOT ENABLED IN CONFIG

Synth devices: NOT ENABLED IN CONFIG

Midi devices: NOT ENABLED IN CONFIG

Timers:
31: system timer

Mixers: NOT ENABLED IN CONFIG

Re: [ALSA] Jest dźwięk, nie ma sterowania głośnością

Nie wiem czy dokładnie w tym problem ale radze zajrzeć tutaj:

http://alsa.opensrc.org/How_to_use_softvol_to_control_the_master_volume

Podobno nie wszystkie sprzęty/ster mają zaimplementowany kanał master i stąd takie jaja. - pytanie, co się dzieje jak chcesz wywołać np alsamixer?

Re: [ALSA] Jest dźwięk, nie ma sterowania głośnością

alsamixer co ciekawe wyświetla paski do regulacji, poruszanie nimi jednak nie zmienia głośności.

Dzięki za przykład z softvol, spróbuję wieczorem.
