I have some additional information that may help. As before, when I have:
pcm.!default {
type hw
card 0
}
pcm.hw {
type hw
card 0
device 0
subdevice 0
}
ctl.!default {
type hw
card 0
}
ctl.hw {
type hw
card 0
}
....as my alsa.conf, I get:
/usr/share/alsa $ aplay -l
**** List of PLAYBACK Hardware Devices ****
ALSA lib conf.c:3949:(snd_config_expand) Unknown parameters 0
ALSA lib control.c:909:(snd_ctl_open_noupdate) Invalid CTL hw:0
aplay: device_list:213: control open (0): Invalid argument
However, it will allow me to use speaker-test, aplay, and arecord....sort
of.
Whenever I try to record in the format my codec allows, I get:
/usr/share/alsa $ arecord -D default -traw -fS8 -d2 test.raw
Recording raw data 'test.raw' : Signed 8 bit, Rate 8000 Hz, Mono
arecord: pcm_read:1346: read error: Input/output error
If it will help, here is the strace of that:
/usr/share/alsa $ strace arecord -D default -traw -fS8 -d2 test.raw
execve("/usr/bin/arecord", ["arecord", "-D", "default", "-traw", "-fS8",
"-d2", "test.raw"], [/* 7 0

As my codec expects u-law, I am going to create a test file in u-law format
and see if that gives me better results with speaker-test.
