ALSA ../alsa-kernel/ppc/keywest.c:84: tumbler: cannot initialize the MCS

[Grzesiek Sedek]

I had my alsa running fine for a while at some point audio stop working
(must been afer one of upgrades to 9.4 on debian ppc sid)
this is dmesg error I'm getting:

ALSA ../alsa-kernel/ppc/keywest.c:84: tumbler: cannot initialize the MCS

modules are loading ok but no sound.
Thanks for any help.

did you load/build the i2c-keywest driver, too?
the pmac tumbler/snapper requires this for controlling the chip over
i2c.

Yes both i2c-keywest and i2c-core are build and loaded.
I'm really puzzled-I never had any problems like that. I've build few
kernels since alsa stopped using old working .config's and still no
luck.
Thanks

could you check dmasound-pmac driver whether it can be loaded
properly?  if it's ok, i can compare with it.

I did try dmasound-pmac some days ago and it seem to load with no errors
(I'm not sure about it - I'll load it again and check) but there was no
sound from xmms or pd. only one unusual thing I've noticed was "beep"
when ibook go to sleep - indicating that oss sound driver was in fact
loaded and working (at least partly). This is under alsa 0.9.4 and
kernel 2.4.21-ben2 with kernel 2.4.20-ben10 and alsa 0.9.1 everything is
ok.
