Microphone input (iBook G3)
While audio output is working fine on my G3 iBook
(late 2001/early 2002 vintage) (Debian Sarge, Debian
2.6.8 kernel) I can't get any thing sensible by way of recording from
the built-in microphone. One or two old messages seem to sugest that
this should be fixed after about ALSA 0.91 (currently we are at 1.0.6).
The results of trying to record and the more obvious relevant information
follow:
james@ephiny:~$ arecord -f cd tmp.wav
ALSA lib pcm_hw.c:1155:(snd_pcm_hw_open) open /dev/snd/pcmC0D0c failed:
No such device
arecord: main:508: audio open error: No such device
james@ephiny:~$ ls -l /dev/snd/pcmC0D0c
crw-rw---- 1 root audio 116, 24 2004-06-30 11:41 /dev/snd/pcmC0D0c
james@ephiny:~$ groups
james dialout cdrom floppy audio video
james@ephiny:~$ lsmod | grep snd
snd_mixer_oss 23264 0
snd_powermac 44304 2
snd_pcm 119800 1 snd_powermac
snd_page_alloc 13480 1 snd_pcm
snd_timer 29348 1 snd_pcm
snd 67800 8 snd_mixer_oss,snd_powermac,snd_pcm,snd_timer
soundcore 11812 1 snd
Does anyone have any ideas whether there is some other module needed,
whether the whole thing is a non-starter or what???
TIA
James
