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.

We are currently working on this.

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 here. -- Edward Schulz Consulting MTS Network and Storage Products Group LSI Corporation 1110 American Parkway NE Room 12H-205 Allentown, PA 18109-9138 TEL 610 712 2068 MOBILE 732 241 4669 -----Original Message----- From: Marvin Stodolsky [mailto:marvin.stodolsky@xxxxxxxxx] Sent: Wednesday, April 11, 2007 10:38 AM To: Schulz, Edward D (Ed); Sarkar, Soumyendu (Soumyendu) Subject: 0x11c11040 hosted by HDA cards problem 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: ------- ALSA /var/tmp/portage/alsa-driver-1.0.13/work/alsa-driver-1.0.13/pci/hda/../. ./a lsa-kernel/pci/hda/patch_si3054.c:245: si3054: cannot initialize.

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 ?? MarvS
