hey martin,
thanks for the reply..
my /proc/asound/devices is identical to yours:
1: : sequencer
0: [0- 0]: ctl
16: [0- 0]: digital audio playback
24: [0- 0]: digital audio capture
33: : timer
however, i have no entries in my mixer for 'pcm1' or 'monitor', my
mixer consists of:
master | headphone | headphone detection | line
cd | mic | pc speaker | audiomute | beep
if i do pipe of arecord to hex, no data is listed apart from
the first 30-40 lines of header, which i assume means that this
is a hardware issue and not simply a quiet mixer.
and yes, i have two ppc specific kernels installed, both 2.4.21ppc
and 2.4.24-benh.. neither have an effect on this problem.
ciao,

i'm using the g3 internal soundcard (chip=burgandy) with both the
oss-lite and alsa drivers.. neither driver has improved the
situation.. for a bit of clarity, no sound is passed through the
chip, and capture/recording doesn't work for any of the inputs, in
fact in alsa there are no capture devices available at all and an
inspection of '/proc/asound/card0/pcm0c/sub0/status' reveals the
unfortunate message 'closed'..
It is normal that the status has closed unless you are actually recording.
My G4 titanium uses the snapper chip, so we use the same kernel driver.
What do
you have in /proc/asound/devices? I get:
1: : sequencer
0: [0- 0]: ctl
16: [0- 0]: digital audio playback
24: [0- 0]: digital audio capture
33: : timer
If you get a similar entry for capture, we should be able to get it going.
Make sure your "PCM 1" and "Monitor" entries are turned up in your
mixer.
Like Derek I also have a lot of noise problems, but my best results so far
are with PCM 1 set to 75%-85% and Monitor set to 90%. I'm still puzzled how
these two relate.
on the flipside, os9 has no problems with sound
input, which leads
me to suspect that it has control of an internal setting that linux
does not..
Hmm, haven't checked out the Mac OS side yet. Will have to give that a try
sometime.
can anyone shed some light, or perhaps tell me
who to politely
abuse! btw, i tried alsa-user-list but my msg is trapped in the
moderation blackhole...
You could try a friendly mail to: linuxppc-dev(a)lists.linuxppc.org
I'm using the PPC specific kernels from:
http://penguinppc.org/dev/kernel.shtml
so far with the same results you get (the 2.5 tree realy holds the 2.6
kernel now).
But any fixes will be in here first.
