Thank you very much for the advice. I dont need thr queue any more Now almost all midi works again in my application - but now for alsa(instead of oss) But there is another problem now. I use an audixy card in my pc connected to an external amplifier. Even the amplifier is set to the maximal volume, midi synth is quite silent whereas pcm is very loud.
Obviously the problem is in the mixer alsmixer shows me a lot of volumes to adjust, but actually just the volume of "music" show en effect. maximum volume on music makes me hear a silent tune. but "master" and all other volumes do not show(sound) a change in the volume. In my application i can now select where the output goes to 64:0 is the external midi and 65:0-3 is the awe synth 64:0 does not work all the time. but directly piping midi date to the respective /dev/snd/midixxxx always works(i hear a tune on the external keyboard). whats the problem here ? _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
