--- Comment #224 from Rafał Mużyło galtgendo@o2.pl 2010-02-13 19:59:04 --- To fan the flames a little bit more: how does ALSA's pulse plugin work for you ?
For me, it seems to work just fine (WaveOut/DS) and I'm getting MIDI sound through timidity then. Even pulseaudio upstream agrees that alsa is necessary for MIDI.
However, I wonder about that DirectMusic bit - it doesn't seem to work at all, that is apps don't produce any sound. Does it need an external app too ? Unless it's supported by the means of installing native DirectX - that would be quite dissatisfying.
