problems ALSA on iBook2

[Alexander Carot]

Hej to all,

we recently tried to install ALSA on an iBook2 with Nando at CCRMA in
Stanford university but we have some trouble :

The whole installation went pretty fine without any trouble, the module
is installed and loaded and we finally set up the mixer but there's no
sound (neither speakers nor headphone).

Chipset : Tumbler 
OS      : YellowDog 2.2 (Rome)
PPC     : iBook2 600MHz

For us everything looks like a bug. Does anyone have any experiences
with ALSA on iBook ?

Thanks

there was a change about daca and tumbler since rc1 to use the
kernel's standard i2c interface instead of alsa's own one.

you might try the older code if you need it urgently.
the change was committed at June 11, so you can check out the cvs with
the date option June 10, i.e.

	% cd alsa-kernel/ppc
	% cvs co -D20020610

i'll check this problem later.


ciao,

Takashi

We'll try this latter (hopefully today). To expand on the
description of the problem, everything seems to work fine
except there is no sound output from either the speaker or
heaphones (for example: automute works, pluging in a heaphone
mutes the speaker in alsamixer, applications "play" for the
expected time and so on and so forth). The standard oss free
driver that comes with the yellow dog 2.2 kernel (2.4.18
something) works fine.

We tried this version yesterday with the same results (and it
was the correct one as the i2c-keywest <or something like
that> was no longer needed to load the driver). Everything
seems fine but we get no sound output.
