First of all, I would like to thank all those responsible for ALSA. It's a great project.
I have kernel 2.4.20, on-board via8235 and pci als4000, clean compile of alsa-0.9.0rc8a from cvs. I can't get SPDIF to work when I try 'aplay -Dspdif foo.wav'. It spews out this error:
ALSA lib conf.c:2666:(snd_config_hooks_call) functions snd_config_hook_load_for_all_cards returned error: Invalid argument
ALSA lib pcm.c:1733:(snd_pcm_open_conf) Invalid type for PCM spdif definition (id: spdif, value: cards.pcm.iec958)
aplay: main:479: audio open error: Invalid argument
I've read that SPDIF is supported (via DSX3 channel?), or is it? With via8235, I've tested multichannel playback but I can only hear 3 simultaneous MP3s (I used 4 instances of alsaplayer!), the 4th is silent.
What could be wrong? I'm not a programmer, so I don't have any clues, just hunches. I very much appreciate any suggestions!!!
I've included my conf files,logs, procs, etc. I don't know if everything is in order.
[sh]$ cat /etc/modules.conf (added als4000 so I can play midis, dont want to use midi2wav (timidity); is this an overkill?)
