ESS device "1998"

ESS device "1998"

[Mo McKinlay]

I recently obtained an HP Omnibook XE2 laptop. It's a reasonably
nicely-specced machine, although (unsuprsingly) the hardware isn't too
well supported with Linux.

I've given up on the internal modem (I'm 90% sure it's some kind of
software modem, and I have an external anyway), but I'm trying to get
some sort of audio to work via the internal sound device.

Here's the output of 'lspci':

00:00.0 Host bridge: Intel Corporation 440BX/ZX - 82443BX/ZX Host bridge

20:00.0 Ethernet controller: Xircom Cardbus Ethernet 10/100 (rev 03)
20:00.1 Serial controller: Xircom Cardbus Ethernet + 56k Modem (rev 03)

I'm currently using 2.2.14 (plus whichever patches RH added for their 6.2
release), and it doesn't seem to be supported. So.. simple question, does
anybody know if this 'card' is supported in a more recent kernel, or
whether there's something in 2.2.14 that works?

[As an aside, from watching Windows boot, it seems to have some sort of
SoundBlaster compatibility, although it seems to lack MPU401 support or
emulation - and any attempts to use the Linux soundblaster stuff seems to
fail miserably :/]

Any hints/clues/etc welcome.

Many thanks,

Mo.

Zab posted the first one out a couple of days ago.

And the modem indeed appears to be the AC97 dumb winmodem on the ESS

Aha - Many thanks! I shall go and experiment, then :)

The chip you are talking about is a maestro-3. It's a hybris chip
between a CSXXXX and an Alegro. The OSS sound drivers support it
already. 
However there is no free driver for it currently out there.
If you get the current maestro open driver to recognize the chip
at least the mixer will start to work.

Maestro3/Allegro: (was ESS device "1998")

As people have mentioned, there is an alpha free driver near
http://www.zabbo.net/maestro3/.  Its not quite up to par yet.  

maybe the web page should talk a bit more about the chip familiy. The
maestro3 has a lot of pieces in common with the maestro2, except for
the part of the chip that did pcm manipulation.  the m3 only has a dsp
where the m2 had specific silicon for doing pcm work.  the allegro
is a "slimmed down" maestro3, and neither have anything to do with
cirrus/crystal CSxxxx parts as far as I know :)

I expect you'll have the 'slow down' problem on the Xe2, we have the
clocking messed up on some implementations (those that don't clock the
thing at 49mhz, as god intended? :))

*nod*  Its the usual mc97 codec setup that leaves the hard work for the
processor.  I'm sure one can play around with the dsp on it as well,
but we don't have specs on the dsp's internals.

And if we had dsp specs, it would not help us. There's no freely
available v.34 stack, and v.31bis (14k4, I hope I have it right) is
free but needs port from multithreaded IRIX code.
