I have the same Board (ASUS A7N8X-XE) with Nvidia CK8 and can confirm the problem, using Kernel 2.6.15.3, with Alsa driver from kernel tree and CVS. Using alsa-lib 1.0.11rc2 from debian/experimental (1.0.10+1.0.11rc2-1). Master Playback Volume incl. Master Playback Switch does not work. PCM Volume not working, though PCM Playback Switch is working. Is there a way to figure out, if the hardware has master volume available? Hmm, after skimming over the AC97 standard, Master Volume (incl. switch) is register 02 and for PCM Playback is 18. I did some tests and read the registers from /proc/asound/card0/codec97#0/ac97#0-0+regs First the Master Volume, though the registers are indeed changing there is no effect. Works? | Register 0:02 | Master Volume | Master Playback Switch -------+---------------+---------------+------------------------ no | 0000 | 31,31 | on no | 8000 | 31,31 | off no | 1f1f | 0,0 | on no | 9f1f | 0,0 | off The case is different for the PCM Playback Volume and Switch: Works? | Register 0:18 | PCM Playback Volume | PCM Playback Switch ----------+---------------+---------------------+-------------------- no change | 0808 | 255,255 | on mute | 8808 | 255,255 | off no change | 0808 | 0,0 | on mute | 8808 | 0,0 | off It seems that the change in PCM Playback Volume does not change any registers. The PCM Playback Switch however does work and the playback is muted. Regards, Matthias ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
