A NOTE has been added to this issue. ====================================================================== <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2251> ====================================================================== Reported By: moret Assigned To: tiwai ====================================================================== Project: ALSA - driver Issue ID: 2251 Category: PCI - hda-intel Reproducibility: always Severity: major Priority: normal Status: assigned Distribution: Debian Kernel Version: 2.6.17.2 ====================================================================== Date Submitted: 07-02-2006 06:27 CEST Last Modified: 07-17-2006 18:28 CEST ====================================================================== Summary: Speaker sound is fine, but headphones not recognized, so no sound Description: Sound comes through fine on built-in speakers. Plugging in headphones silences the built-in speakers, but nothing comes through on the headphones jack. The machine is a Panasonic CF-Y5 (Japanese market) with L2300 Core Duo processor, 82801G (ICH7) chipset, and the following audio device (from lspci -vv), with device ID 27d8, identified by ALSA as a SigmaTel STAC 9200: 00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02) Subsystem: Matsushita Electric Industrial Co., Ltd.

The results are identical (I saved each and gave them to diff). When the module is inserted, a few lines are saved to /var/log/syslog: here they are ul 6 23:17:18 localhost kernel: ACPI: PCI Interrupt 0000:00:1b.0[A] -> GSI 22 (level, low) -> IRQ 185 Jul 6 23:17:18 localhost kernel: PCI: Setting latency timer of device 0000:00:1b.0 to 64 Jul 6 23:17:18 localhost kernel: codec_mask = 0x1 Jul 6 23:17:18 localhost kernel: hda_codec: Unknown model for STAC9200, using BIOS defaults Jul 6 23:17:18 localhost kernel: autoconfig: line_outs=0 (0x0/0x0/0x0/0x0/0x0) Jul 6 23:17:18 localhost kernel: speaker_outs=1 (0xe/0x0/0x0/0x0/0x0) Jul 6 23:17:18 localhost kernel: hp=0xd, dig_out=0x0, din_in=0x0 Jul 6 23:17:18 localhost kernel: inputs: mic=0x10, fmic=0x0, line=0x0, fline=0x0, cd=0x0, aux=0x0 Jul 6 23:17:18 localhost kernel: hda_intel: azx_get_response timeout, switching to single_cmd mode... ---------------------------------------------------------------------- moret - 07-17-06 18:28 ---------------------------------------------------------------------- Partial resolution: I just added a new stanza to pci/hda/patch_sigmatel.c, copying lines 267-270 to create the extra stanza { .modelname = "CFY5", .pci_subvendor = PCI_VENDOR_ID_INTEL, .pci_subdevice = 0x27d8, /* /sys/class/sound/audio/device/device */ .config = STAC_REF }, /* seems to work */ This avoids having the routine static int patch_stac9200(struct hda_codec *codec) fail to obtain a valid spec->board_config; the original patch_sigmatel.c would result in the error message hda_codec: Unknown model for STAC9200, using BIOS defaults but this no longer happens with the extra stanza. What matters is that headphones now work ;-) On the other hand, this is only a partial resolution: neither alsa nor xmix provides a mixer entry for the headphones, so sound volume has to be controlled through speaker volume.
