We have two reports now of unstable volume levels:

This is with kernel 2.6.23 plus the two ALSA merge patches from 2.6.23-rc1. _______________________________________________ Alsa-devel mailing list Alsa-devel@alsa-project.org http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
Probably this isn't a software bug. Probably this chip country to datasheet doesn't have usable "Master Volume" (volume knob) control.
The master volume control wasn't present before, I added support for it, using data-sheets. I need to know what exactly sigmatel codec was used in both cases.
Yes, the latter case seems with STAC9205 but the former one (361051) isn't clear. Please check /proc/asound/card0/codec#* entries.
thanks,
Takashi
The former is also STAC9205/04/ since it is the only one with analog loopback and two ADCs
I have question, I talked with the reporter of 354981, and I don't know why but his amixer gives very strange results:
[root@itse68482 ~]# cat amixer-contents-kernel-2.6.23.2-36 numid=0,iface=MIXER,name='Master Playback Switch' ; type=BOOLEAN,access=rw------,values=1 : values=on numid=0,iface=MIXER,name='Master Playback Volume' ; type=INTEGER,access=rw------,values=2,min=0,max=65536,step=1 : values=65536,65536 numid=0,iface=MIXER,name='Capture Switch' ; type=BOOLEAN,access=rw------,values=1 : values=on numid=0,iface=MIXER,name='Capture Volume' ; type=INTEGER,access=rw------,values=2,min=0,max=65536,step=1 : values=34953,34953
How can that be?
Is the codec accessed properly? This looks like the error at reading amp capability of these NIDS and returned -1. The volume attributes are extracted from the amp caps. But if so, usually relevant kernel messages appear...
