Subject: Ali5451 and MIDI synth

I'm trying to get MIDI synth happening with the Ali M5451 audio chipset
(as found in the Toshiba 1800 notebook).

So far, it appears to me that:

* linux-2.2 has MIDI support in the code (v0.14.5c of trident.c) - but
this driver (a) doesn't work for basic audio[1] and (b) doesn't register a
MIDI synth device (and MIDI players complain of no device).

* linux-2.4 has no MIDI support in the code (v0.14.9d of trident.c) - this
driver works OK for basic audio.  Oddly, I can't see any mention of the
MIDI code removal in the driver's history.

* ALSA-0.9 - no MIDI support in the code (alsa-kernel/pci/ali5451/*).

Have I missed something here?

Thanks,
Neale.

[1] "doesn't work for basic audio" includes this being logged to kern.log:

	trident: drain_dac, dma timeout?

Interestingly, I can make this go away by first loading and unloading the
ALSA drivers then loading the OSS drivers.  This makes me suspicious that
linux-2.2's OSS driver is missing something in the initialisation.
