Hello,
I can't get native alsa midi clients to work with my setup (SB Live! +
external keyboard + ALSA 0.9.0beta10 + 2.4.16pre1).
OSS emulation works fine though, for both internal and external MIDI, as
verified with "playmidi -D 0 -e" and "playmidi -a"
Here's what goes wrong:
$ pmidi -l
Port Client name Port name
$ aconnect -l -i -o
client 0: 'System' [type=kernel]
0 'Timer '
1 'Announce '
Connecting To: 63:0
client 64: 'External MIDI 0' [type=kernel]
0 'MIDI 0-0 '
client 65: 'Emu10k1 WaveTable' [type=kernel]
0 'Emu10k1 Port 0 '
1 'Emu10k1 Port 1 '
2 'Emu10k1 Port 2 '
3 'Emu10k1 Port 3 '
$ pmidi -p 64:0

I tried "dd if=/dev/snd/midiC0D0 bs=1" , it works, I can see different input
when sending midi events from the external midi keyboard.
My modules.conf is fairly standard, I think:
alias char-major-116 snd
alias char-major-14 soundcore

soundcore 3684 6 [snd]
I'd be very grateful if someone could give me a hint about that !
I have another problem: after removing all snd-* modules, I can't seem to
unload snd (and therefore soundcore), it says it's busy even though I'm
pretty sure no process is using sound. Strange but annoying.
thanks for any help
