Is there any additional technical information? Could someone be so kind and forward it to me? The driver is easily readable, but it wouldn't hurt if I had the original documents still. Two more things: - The driver uses inlined functions quite extensively. But I think, that gcc does not inline functions, at least not with -O2 optimization, which was default (I tried -finline-functions, hdsp.o was different afterwards). - In snd_hdsp_interrupt: The first four lines determine, why the interrupt was triggered (audio, midi0, midi1). Now the MIDI code further down does not use that information, but the MIDI status instead. Could that be the cause for the audio dropouts, that happen now and then, when MIDI is received?
