[Alsa-user] Can't use timidity

[Alex A. <ale...@ta...>]

I've followed the instructions to use TiMidity as the ALSA sequencer client. 
I've installed TiMidity (2.11.3) with the following configuration:

./configure --enable-audio=alsa --enable-alsaseq --enable-gtk 
--enable-spectrogram

I then installed ALSA (0.9.0) . When I try to execute 'timidity' (e.g. 
"timidity -iA -B2,8 -Os -EFreverb=0") I get the following error message:

/dev/snd/pcm00: Sound protocol is not compatible
Couldn't open ALSA pcm device (`s')

The device "/dev/snd/pcm00" doesn't actually exist. In the "/dev/snd/" 
directory I have things like "controlC0", "midiC0D0" and "pcmC0D0c".

Any ideas?
