It is clearly only half-duplex when the DSP is in high-speed mode. It is
less clear what will happen in low-speed mode if one tries to capture during
playback or vice versa. I don't know if the Jazz16 needs high-speed mode at
all, so I'll do some testing.

I don't recall having ever managed to generate an MPU interrupt. I have
no MIDI hardware.

Mine has an IDE port, jumper A for 0x1f0/0x3f6, jumper B for 0x1f0/0x376,
jumper "CDROM IRQ" for 10, 11, 14 or 15. J9 & J10: 1-2 AMP OFF, 2-3: AMP ON.
Note that my board is rather anonymous. For all I know, it could be an
OEM one.

Here goes (following a change of DMA maps in the PnP driver):

Playback sounds normal except for a click for each "pointer ..." message.
Any ideas? /proc/interrupts increments by 11.

Guesswork: MAB0/1 to select SCSI BIOS memory address, DAB0-2 to select
NCR chip SCSI device ID - does it happen to be set to 7? DAB0-2 could also
tbe the NCR chip base address.

Does that also include the SCSI part?

Line out left/right amplifier on/off, I guess.
