Hello,
I've bought a new laptop Dell Vostro 1400 with the following audio card:
00:1b.0 Audio device [Class 0403]: Intel Corporation 82801H (ICH8 Family) HD Audio Controller [8086:284b] (rev 02)
and with the SigmaTel Codec:
Codec: SigmaTel STAC9228 Address: 0 Vendor Id: 0x83847616 Subsystem Id: 0x10280227 Revision Id: 0x100201
I was able to get sound to come out of the internal speakers by explicitly specifying either the 3stack or the dell-3stack models with alsa 1.0.14 . Unfortunately with neither of those does the internal microphone work.
Now I am running ALSA HG and have decided to try and fix my problem by adding the proper pinconfig for my card (this is what I've done before for my Mac and it worked). I downloaded the win32 drivers which include all pinconfigs for all Dell machines with intel hda cards. The problem I am facing is that the win32 driver .ini provides a configuration for 13 pins which do not match the ones in patch_sigmatel.c . The ones in ALSA are:
static hda_nid_t stac922x_pin_nids[10] = { 0x0a, 0x0b, 0x0c, 0x0d, 0x0e, 0x0f, 0x10, 0x11, 0x15, 0x1b, };
Where as the ones defined by the driver are [1]: 0x0a, 0x0b, 0x0c, 0x0d, 0x0e, 0x0f, 0x10, 0x11, 0x12, 0x13, 0x14, 0x21, 0x22
This looks rather like stac927x_pin_nids[]. STAC9228 belongs to patch_stac927x(). patch_stac922x() is only for STAC9220 and STAC9221.
