I've just committed stereo support of the opl (OPL3) device.

Here, I have a problem.
I tried this on my cmpci (CMI8738/PCI-6ch-MX) board,
and I found the left and right channels are swapped.

Does anyone have heard about this?
How does it work on your devices?
I tested this on ym (OPL3-SA3), and have no such problem.

If you want try this on cmpci device, use config like this:

	cmpci*	at	pci? dev ? function ?
	audio*	at	cmpci?
	opl*	at	cmpci?
	midi*	at	opl?

I attach a sample MIDI file, which first plays on the left side,
and then on the right side.

	midiplay -d <midi-device#> <attached-file>

I'm now analyzing and re-implementing cmpci mixer.  Please be patient...
