/dev/snd/pcm00: Sound protocol is not compatible
Couldn't open ALSA pcm device (`s')
Ok, I checked for /dev/snd/pcm00 and it does not exist! /dev/snd does
not exist. Ok, so something must have gone wrong during OS installation
I guess.
I ran snddevices from the lastest ALSA from their web page, and it
created /dev/snd -> /proc/asound/dev, but /proc/asound/dev/pcm00
doesn't exist either:
dione:/dev# ls -l /proc/asound/dev
total 0

crw-rw---- 1 root audio 116, 8 Jun 14 16:50 midiC0D0

crw-rw---- 1 root audio 116, 1 Jun 14 16:50 seq
crw-rw---- 1 root audio 116, 33 Jun 14 16:50 timer
(I also tried searching www.debian.org to determine which packages
'snddevices' and /dev/snd belong to, but they say none, which is
maybe which they were missing from my installation.)
I tried now running Timidity without '-Os'; presumably it'll route
audio to the OSS devices, but the source MIDI events will still come
via ALSA? That produced the following:
dione:/dev# timidity -iA -B2,8 -EFreverb=0
TiMidity starting in ALSA server mode
set SCHED_FIFO
error in snd_seq_create_simple_port

Ok, I'll give that a go - mine is 2.10. But can you confirm that the
differences between 2.10 and 2.12 would cause the error above? It'd
be nice to upgrade and not get the same error :-)

If 'aconnect' should work, then I'll try that first, since it's
already on the machine, whereas alsa-patch-bay isn't.

Ok, that looks good:
dione:~# aconnect -li
client 0: 'System' [type=kernel]
0 'Timer '
1 'Announce '
Connecting To: 63:0
client 64: 'External MIDI 0' [type=kernel]
0 'MIDI 0-0 '

Ok, as explained above Timidity crashes immediately; so those are
not listed:
dione:~# aconnect -lo
client 64: 'External MIDI 0' [type=kernel]
0 'MIDI 0-0 '

I think I don't understand what you mean by 'program' in this context
:-)

Going back to alsaplayer again: having created the /dev/snd symlink
with snddevices, alsaplayer now does something a bit different:
dione$ alsaplayer
...done playing
dione$
and with a real file as parameter the same:
dione$ alsaplayer /pub/multimedia/audio/radio/ragtime/zuza.au
...done playing
dione$
But still no sound; volume *is* turned up (xmms works). If I tell
alsaplayer to use a specific device under /proc/asound then I'm back
to a variation on the old error:
dione$ alsaplayer -d /proc/asound/dev/pcmC0D0p
/pub/multimedia/audio/radio/ragtime/zuza.au
ALSA lib pcm.c:1599:(snd_pcm_open_noupdate) Unknown PCM
/proc/asound/dev/pcmC0D0p
snd_pcm_open: No such file or directory (/proc/asound/dev/pcmC0D0p)
/usr/lib/alsaplayer/output/libalsa.so failed to load
I could not find a suitable output module on your
system. Make sure they're in "/usr/lib/alsaplayer/output/".
Use the -o parameter to select one.
failed to load output add-on. exitting...
dione$
And the same if I use the 'p' pcm device instead of the 'c' one.
Any more ideas? Thanks for the advice so far; some progress!
Alexis
