For those of you with
Vendor ID 0x11c11040 softmodem chips, there is Bad News.
These chips hosted by High Definition Audio cards cannot be made
functional by Public efforts alone to the snd-hda-intel code.
0x11c11040 is a new  chip type, i.e. not a specialization of the
Silicon Instr.  Si3054 chip as initially assumed.

The Hope however is that a Linux code team at LSI Corporation,
successor to AgereSystems, is working towards support this 0x11c11040
chip and will keep us appraised of developments.

Some details below.  Because LSI does not wish general contact with
the public on these issues, LSI email addresses have been deleted.

Current we do not have Linux driver that supports HDA bus. We are
currently working on this.

11c1 1040 is not a SiLabs chipset; it's all ours (was Agere Systems, now
LSI Corp).  We have Linux drivers for this soft modem.  I'll let Ashok
Vernekar, the manager of the soft modem driver group, work with you from

Ed & Soumenyendu

The Linmodems group is trying to bring 0x11c11040 into service under the
ALSA snd-hda-intel.ko  driver, with the (former Smartlink) slmodemd
utility providing the higher level services.  This support strategy does
work for the chips  AgereSystems chips 0x11c13026  and
 0x11c13055  hosted on a variety of High Definition Audio cards.

However with the 0x11c11040, there is a failure under initial hardware
probing like:
lsa-kernel/pci/hda/patch_si3054.c:245: si3054: cannot initialize. EXT
MID = 0000 HDA Intel: probe of 0000:00:1b.0 failed with error -1

Below is info from the ALSA  diagnostics written to
/proc/asound/card0/card#1 for a few 0x11c11040 cases:

Codec: Generic 11c1 Si3054
CAddress: 0
Vendor Id: 0x11c11040
Subsystem Id: 0x11790001
Revision Id: 0x100200

Codec: Generic 11c1 ID 1040
Address: 1
Vendor Id: 0x11c11040
Subsystem Id: 0x103c1378
Revision Id: 0x100200

Codec: Generic 11c1 ID 1040
Address: 1
Vendor Id: 0x11c11040
Subsystem Id: 0x11c10001
Revision Id: 0x100200

Could you possibly provide some guidance that would aid us with the
0x11c11040 chip??
What are cogent differences between the serviced 0x11c13026  and
 0x11c13055 chips and the still troublesome 0x11c11040??
Is 0x11c11040 really written on a Si3054 chip, as this is really just
our guess ??
