ESS Maestro 3i support status

ESS Maestro 3i support status

[Dr. Michael Weller]

Dear List,

I've a Dell Laptop here with an ESS Maestro 3i Sound card build in. I
cannot get the card to work. The card seems to be sb compatible
(iobase 0x220, irq 5, dma 1, 0x388 for adlib emulation, no 16bit dma).
The BIOS even prints these settings during boot as used for DOS sound
support.

I had to modify the pcmcia setup to not claim the ioports as used and
since then the sb driver does not whine about their missing.

However, it cannot initialize the card. All I get is a message the sb
module fails to reset the dsp. Then EBUSY error from insmod (I would have
found ENODEV more intuitive, btw.) 

Now, question: Is this a configuration problem (and how can I fix it) or
is the card simply incompatible and their is no chance to make it work.
The ess137[01] drivers did also fail but made no comment about the
reasons, BTW.

All this is with kernel 2.2.14, btw.

Any comments are appreciated, thank you in advance,
Michael.

I just learned about the OSS maestro driver. It does, however, only
support Maestro 1, 2 and 2e. I hacked the the module to accept the Maestro
3i as one of those and the module installed but produced many Cannot
select APU register warnings. I could change mixer setting (even got
crackles while adjusting it), but it did not produce any sound.

Any comments are appreciated, thank you in advance,
Michael.

That won't work; the chips are sufficiently different that you
can't program them in the same way. You can either initialize
it in DOS and then warm boot to linux and use the SB compatiblity,
or wait for the specs on how to program the ASSP to appear from
ESS.

Aha, so even for SB compatiblity, I need a dos driver to program the card
first?
