We have two reports now of unstable volume levels:

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?
According to his lspci, he doesn't have a second sound card.
Any ideas?
Besides that it seems that VolumeKnob is physically broken on
STAC9205s,
Can anybody here with STAC9205/STAC9204/STAC9254/STAC9255 test it?
And last question, about STAC9254/STAC9255 There is no datasheet for that chip on the web, is this just
STAC9205
modem?

The STAC9254/55 lines are not available anymore. Yes, they were basically 9204/5 + Modem.

Hi,
Thanks a lot,
Just one more question, are data-sheets for STAC9872 aviable? I don't even see a page describing those chips on IDT website.
No, datasheets are not available.
Furthermore, recently IDT sent a patch for STAC92HD71BXX, thus I want to ask whenever datasheets for it will be available.
Datasheets are available on IDT.com
