This laptop is detected as ALC892 audio (and by the codec ID this seems to be valid), but none of the configurations for it quite match this device. I've been working on documenting the connections with HDA Analyzer.
alsa-info output: http://www.alsa-project.org/db/?f=b86e4c6447867fbd129a36d8a63e2f5caa836c52
The laptop has built-in 5.1, and 5.1 or 7.1 output via jacks.
DAC NIDs: 0x02 front 0x03 rear 0x04 clfe 0x05 side
internal mixers: 0x0c front 0x0d rear 0x0e clfe 0x0f side
internal speaker pins: 0x14 front 0x15 "rear" (front of laptop) 0x16 clfe
external ports: fixed route: 0x17 side
can select any output: 0x18 mic / output 0x1a line-in / output 0x1b headphone
I've been experimenting with patch_realtek.c to add the extra DAC NID, and have had some success with a 6-channel mode for the built-in speakers and an 8-channel mode that mutes all internal speakers and sets the jacks up for output. I still need to manually connect pins 0x18, 0x1a, 0x1b to the correct internal mixers for 7.1 to work, and headphone plugin does not mute internal speakers in 5.1 mode. I have not added a plain stereo mode for internal speakers, although it appears that i can probably configure the codec to mix the front channels to center and LFE.
Are there any suggestions for what to do next? My current state as a patch against the linux-3.0.y repository is at http://pastie.org/2400649
your patch only support 6ch and 8ch , you have to add alc892_clevo_p170hm_ch2_init() ch for stereo playback and ext mic and line-in jack
seem the bios did not setup "side" jack 0x17 ?
autoconfig: line_outs=3 (0x14/0x16/0x15/0x0/0x0) type:speaker speaker_outs=0 (0x0/0x0/0x0/0x0/0x0) hp_outs=1 (0x1b/0x0/0x0/0x0/0x0) mono: mono_out=0x0 dig-out=0x1e/0x0 inputs: Mic=0x18 Internal Mic=0x19 Line=0x1a
seem need to add pin default of side jack 0x17 to force the auto parser to put those speaker pins in correct places
Node 0x17 [Pin Complex] wcaps 0x40058d: Stereo Amp-Out Amp-Out caps: ofs=0x00, nsteps=0x00, stepsize=0x00, mute=1 Amp-Out vals: [0x80 0x80] Pincap 0x00000036: IN OUT Detect Trigger Pin Default 0x411111f0: [N/A] Speaker at Ext Rear Conn = 1/8, Color = Black DefAssociation = 0xf, Sequence = 0x0 Misc = NO_PRESENCE Pin-ctls: 0x40: OUT Unsolicited: tag=00, enabled=0 Power states: D0 D1 D2 D3 EPSS Power: setting=D0, actual=D0 Connection: 1 0x0f

and sort the speaker pin by default association 02, 03, 04 (0x14, 0x15 and 0x16) when all pin defaults have same location
autoconfig: line_outs=1 (0x17/0x0/0x0/0x0/0x0) type:line speaker_outs=3 (0x14/0x16/0x15/0x0/0x0) hp_outs=1 (0x1b/0x0/0x0/0x0/0x0) mono: mono_out=0x0 dig-out=0x1e/0x0 inputs: Mic=0x18 Internal Mic=0x19 Line=0x1a
Please check out this thread: http://thread.gmane.org/gmane.linux.alsa.devel/86475 With linux-3.1, everything apart from 8-channel sound seems to work with autoparser, and I was able to get the sound going out from the analog part of the spdif jack by fiddling with hda-analyzer: http://article.gmane.org/gmane.linux.alsa.devel/87235 To get this to work automatically, code needs to be written but this is beyond my skillset.
Keep in mind that IIRC P170HM has 4.1 speakers while P150HM has 2.1. I think the other audio outputs are the same.
internal speaker pins: 0x14 front 0x15 "rear" (front of laptop) 0x16 clfe
Do you mean the speaker info is incorrect as there is no center ?
0x16 is a stereo pin, and you have to check whether the subwoofer is connected to left, right or both
Let the auto parser to put the speakers pin in autocfg 's line out won't help
the four jacks need alc883_4st_8ch mixer of "targa-8ch-dig" which has been removed
http://git.alsa-project.org/?p=alsa-kernel.git;a=commitdiff;h=7a689ebcefe5fe...
The main problem is the signal of "rear" speaker of the notebook is not really at the rear of the user.
I cannot speak for P170HM as I do not have one, but on P150HM there are two speakers between the screen and the keyboard and something supposed to act as a subwoofer on the bottom side of the laptop. On Windows 7 you need THX TruStudio PRO to make it work. No center speaker that I know of. There are service manuals with schematics for these laptops floating around the internet. ALC892 connections are described on page 86 for P150HM and page 91 for P170HM. You should be able to understand far more than I.
