is it possible to support multiple mixers in one card?
I have the following situation:
The card consists of a Maestro2E PCI controller with AC97 codec. On
the expansion port of the maestro is a SAM9707 device. I'd like
separate mixers for the AC97 and the SAM, because the

yes, but the implementation depends on the driver.

Did you try to set 16bit DMA allocation flag to Playback or Capture?
Also, there are problems if your ISA bus is overclocked to more
than 8MHz.

In this state, 8bit IRQ is still pending! It looks that with some SB DSP

Attached patch (untested!) acknowledges [16|8] bit interrupt, but adds
[8|16] bit acknowledge, if secondary channel is not in use at the moment.
Hello!
This patch is a rework of OPL3 chip detection (again...):
- detects OPL3-L
- detects OPL4 with by-the-book procedure. FM registers can not be
read in OPL4 mode (look at page 8 of OPL4 documentation)
- changes messages to OPLx ...
- enhances reported chip

For EWS64XL (at least for my rev 1.2) you should use cs4236. It worked
for me a couple of weeks ago. In fact, you don't need to initialize
a sam9407 device to use CoDec device with latest ALSA revision.

Is the opl3 autodetection supposed to fail for this chipset ?
Yes. Autodetection is made by changing timer value. In CirrusLogic case,
and according to comment, there is no OPL3 timers in Cirrus Logic's chips.
