Is it an ALSA bug to display STAC9705 as STAC9704 ?

Is it STAC9705 ?

18-bit full-duplex audio codec with intergrated modem analog front end.

http://www6.tomshardware.com/mobile/20010126/notebooks-06.html

What is the usage of MOT6269353 if it already connected to STAC9705 ?



It is likely secondary modem-only codec (Motorola/SiLabs).

Philipp,


MOT6269353 and MOT6269352 is an AC-Link SM56 Building block.

http://www.motorola.com/softmodem/driver.htm
Is it normal to have a primary audio/modem codec STAC9705 and a secondary codec (AC-link SM56) ? 

I guess DAA Si3014 is similar to MOT6269352



Could you try the patch below? And then look again at '/proc/asond/au8810'?

This is against CVS, untested and may be dangerous because I know nothing
about au8810 (somebody knows, please comment).

Sasha.



At a first glance, it's rather DANGER to try your patch.

The LAN card and MDC share the RJ11 jack on l8400b

Does it need to disable the LAN in BIOS before you make any test on the
MDC ?

Photo of Aureal sound cards can be found in

http://www.dearhoney.idv.tw/MUSEUM/soundcard-07.php

Turtle Beach Montego II (STAC9721) is supported but the rear speakers of
Quadzilla and the rear speakers and SPDIF IN/OUT of Home Studio Daugther
card are not yet supported.


JP1 of SQ2500 is connect to the WaveBlaster daugther card.

http://www.dayc.vispa.com/faq/vtximg.htm

JP2 and JP3 of SQ2500 are connected to SQ3500 daugther card with
Motorola DSP56362.

The usage of the 20-pins connectors at the top of SuperQuad is unknown.

It seem all Vortex cards (e.g. Turtle Beach Montego, Diamond S90,... )
have only one stereo codec and do not support soft modem.

SQ1500, Aureal Advantage and most of the au8810 sound cards do not
has any seconday modem codec.

SoundCom PCI Audio/Modem Combo card and some motherboard with
onboard au8810 (e.g. ASUS l8400b, MS-6178E) have aureal soft modem




http://pci-ids.ucw.cz/iii/?i=12eb8803

I suspect Aureal VCOM PCI Modem Card has different PCI vendor/device id
12eb:8803


I suspect SQ1500 is the only au8810 has a quad codec (need confirmation
from SQ1500 user).
