Using 2.5.71 hit the same problem. Next, I have used the 2.5.70 source tree for the 2.5.72 build, but the problem persists. I have then straced the command "amixer set Master 50 unmute" on both 2.5.70 and 2.5.72, which revealed that on .72 /dev/snd/controlC0 is not created (the mixer program cannot open it), because /dev/snd is a symbolic link to /proc/asound/dev which does not exist. What am I missing? I am not on the mailing list, so if possible CC to celestar@t-online.de Thanks in advance.
