Problem 1:
I can't record anything with my soundcard. Playing is no problem. I
checked and found out that a call
open("/dev/dsp", O_RDONLY);
fails, but
open("/dev/dsp", O_WRONLY);
succeeds.
Some programs (like audacity) will therefore leave my soundcard in a bad
state: I am not able to play any sound afterwards, either.
Used sound drivers:
> lsmod
Module Size Used by Not tainted
dmasound_pmac 70640 0 (autoclean)
dmasound_core 13496 0 (autoclean) [dmasound_pmac]
soundcore 4616 3 (autoclean) [dmasound_core]
If you are talking about the little microphone top-right of the screen:
IIRC you will have to wait for the 2.6 kernels with alsa since dmasound
isn't supporting recording (I guess externel USB Microphones won't work
either).
Concerning a broken sound which here is sometimes caused by quake2 I
simply reload the soundmodules (rmmod..insmod) via a script and
everything is back (also I sometimes have to kill the app that is using
dsp [fuser /dev/dsp]).
