Hi, quick question for the list. Has MIDI support been implemented
for the hda-intel codec, specifically the sigmatel codec. I tried
playing a MIDI file the other day, and could see the levels bouncing
around, but no sound whatsoever. Basically, does the driver not
support it, or am I doing something wrong?
Thanks,
Nick

The HD-audio doesn't support the MIDI playback in hardware.
Everything is software rendering.

Thanks Takashi. So to clarify, the HDA driver supports MIDI, but not
through the hardware? So if I play a MIDI file, it should in fact
work?
Thanks,
Nick

You'll need to use a softsynth, e.g., fluidsynth, timidity, and be aware
that, depending on the desktop distro that you use, you may encounter races
with other apps attempting to access the device.

No and no. It's no job of a driver but a user-space application
who renders the MIDI data to PCM.

Use an application (or a sound subsystem) supporting software
MIDI rendering. fluidsynth, timidity, whatever.

Thanks to both of you, that's exactly what I was looking for.
