problems getting going via 82cxx ...
Below I've included details of my whole setup, and some other notes, but
to start with here's the strace from a failed mplayer test:
write(1, "alsa-init: requested format: 441"..., 81alsa-init: requested
format: 44100 Hz, 2 channels, Signed 16-bit (Little-Endian)
) = 81
open("/dev/snd/controlC0", O_RDONLY) = 7
close(7) = 0
write(1, "alsa-init: 1 soundcard found, us"..., 44alsa-init: 1 soundcard
found, using: hw:0,0
) = 44
stat(umovestr: Input/output error
0, 0xbfffe7fc) = -1 EFAULT (Bad address)
write(2, "ALSA lib ", 9ALSA lib ) = 9
write(2, "pcm.c", 5pcm.c) = 5
write(2, ":", 1:) = 1
write(2, "1906", 41906) = 4
write(2, ":(", 2:() = 2
write(2, "snd_pcm_open_noupdate", 21snd_pcm_open_noupdate) = 21
write(2, ") ", 2) ) = 2
write(2, "Unknown PCM ", 12Unknown PCM ) = 12
write(2, "hw:0,0", 6hw:0,0) = 6
write(2, "\n", 1
) = 1
write(1, "alsa-init: playback open error: "..., 58alsa-init: playback
open error: No such file or directory
) = 58
write(2, "Could not open/initialize audio "..., 52Could not
open/initialize audio device -> no sound.
) = 52
OK here's my various config files:

Using 0.9.4 lib/driver/utils ... with kernel 2.4.21-ac1/. Utils are
compiled with UCLIBC- would that make a difference?
If I force mplayer to use OSS, then the file plays ok but there's no
sound. Yes, I know that's because of the muting- and I'm sure it's that
because if you turn the amp way up you can just about hear the song
faintly. So, trying to unmute the line, or just trying to run alsa mixer
for that matter gives the following (output from an strace)
rt_sigaction(SIGRT_1, {0x400e5c2f, [], 0x4000000}, NULL, 8) = 0
rt_sigaction(SIGRT_2, {0x400e5d1f, [], 0x4000000}, NULL, 8) = 0
rt_sigprocmask(SIG_BLOCK, [RTMIN], NULL, 8) = 0
brk(0x80528f0) = 0x80528f0
brk(0x8053000) = 0x8053000
brk(0x8054000) = 0x8054000
brk(0x8055000) = 0x8055000
brk(0x8056000) = 0x8056000
stat(umovestr: Input/output error
0, 0xbffffa7c) = -1 EFAULT (Bad address)
write(2, "ALSA lib ", 9ALSA lib ) = 9

write(2, "default", 7default) = 7
write(2, "\n", 1

write(2, "alsamixer: function ", 20alsamixer: function ) = 20

write(2, "No such file or directory", 25No such file or directory) = 25

_exit(1) = ?
I'd really appreciate it if someone could help with this... I've been
googling and reading notes in archives for ages, and nothing is really
helping me so far... one thing I have noticed is that in the straces I
do, I don't see any evidence of trying to read asound.conf .. ?????
TIA
Chris
