That wasn't really an option. But I did look at the file permissions
for the device directory and they were severely messed up. So I have
spent the evening doing a clean rebuild and I can again get the oss
emulation to work correctly - it will play arbitrary pcm samples.
So I think that indicates the kernel side and the device driver are working.
But I still seem to have an alsa-lib/alsa-tools problem - viz
# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: AICA [AICA], device 0: AICA PCM [AICA PCM]
Subdevices: 1/1
Subdevice #0: subdevice #0
# aplay -L
null
Discard all samples (playback) or generate zero samples (capture)
# aplay /aine-email.wav
Playing WAVE '/aine-email.wav' : Unsigned 8 bit, Rate 8000 Hz, Mono
ALSA lib pcm_plug.c:773:(snd_pcm_plug_hw_refine_schange) Unable to
find an usable access for '(null)'
aplay: set_params:895: Access type not available
# aplay --device=0 /aine-email.wav
ALSA lib pcm.c:2144:(snd_pcm_open_noupdate) Unknown PCM 0
aplay: main:545: audio open error: No such file or directory
Any clues as to why this would happen? (As I said, this sample will
play correctly through oss emulation)
