After the pin fixup, your notebook is almost like alc1200 msi gx460 except speaker and hp are swapped, this mean that those volume controls and switches are similar to targa_mixer , targa_8ch_mixer of model="targa-8ch-dig"

The are some difference between p170hm and your p150hm if p170hm has 5.1 speakers which still can have auto mic detection enabled.
you can add the following code in alc_auto_ch_mode_put() for debugging and need to switch "auto mute mode" to "speaker" for 8 channels
if (spec->need_dac_fix && !spec->const_channel_count) spec->multiout.num_dacs = spec->multiout.max_channels / 2;
printk(KERN_INFO "ch = %d\n",ch);printk(KERN_INFO "max channel %d\n",spec->multiout.max_channels);for (i=0; i<spec->autocfg.hp_outs; i++)printk(KERN_INFO "hp dac(%d) %x pin %x\n", i,spec->multiout.hp_out_nid[i], spec->autocfg.hp_pins[i]);

This is what appears in /var/log/messages if you go from 8 to 2 channels and back:

I applied the attached patch and 2, 4, 6 and 8 channel sound is working, enabling outputs incrementally as I change the number of channels in alsamixer. Observations:
- there is no mute for side channel
- no matter if Auto-Mute is set to Speaker or Line Out+Speaker, speakers
will mute upon plugging a jack into either headphone or side/spdif socket
- there is a "front" slider which controls internal speakers and HP
jack, but the mute control under it does nothing. There are separate mute controls for HP and Speakers, which work as advertised. This is the alsa-info.sh output: http://www.alsa-project.org/db/?f=7df8ccac0a5ae751110f7b7e56f9e0ba5cc3b302 Looks like we are almost there, thanks for all the input so far!

- mute for side channel is present and functions correctly
- auto-mute situation is unchanged, but I don't think it matters
- speaker/HP controls are much neater
- front mute and slider control the internal speakers
- headphone mute and slider control the headphone jack
The only nitpick would be that the alt device does not work:
There was a patch which add "Independent hp" swtich and create device 2 for alc892 desktop with 6 jacks at rear panel

I tried 0001-Add-Multistreaming-Playback-using-Front-Panel-Headph.patch, but unfortunately it does not apply on top of current kernels anymore, and it is not trivial enough for me to fix. Anyway, in my opinion it does not make a lot of sense, as the jacks are 2 cm away from each other and I don't see a use case where someone would want to play a different sound on each of them.

And that the sound is coming out of the side jack no matter the number of channels.
b) use "Headphone" for "alt playback"
In function alc_auto_fill_dac_nids()
spec->alt_dac_nid = spec->multiout.hp_out_nid[0]; return 0;I also tried this version (attached with versionb suffix), it works even better. As with version a), controls are working correctly. Auto-mute still mutes upon plugging into either side or headphone jack no matter the alsamixer setting. Alt device is still not there. The improvement is that sound only comes out of the side jack when alsamixer is set to 8 channels.

So it seems like the version b does everything it is supposed to, maybe aside from the side jack muting behaviour. Summing up, when it comes to P150HM, the only missing piece is the internal subwoofer. I tried emailing Andrew, who started this thread, but got no answer so far. The problem might be that we might need to figure out what is that THX TruStudio PRO is doing under Windows that makes the internal subwoofer work.
Take a look at the removed model="targa_8ch_dig" which touch those gpio
Have you ask the notebook vendor clevo support/engineer the subwoofer is connected to which pin of alc892 ?
I have just sent an email to Clevo UK Support. Let's see what they answer.
I was forwarded to realtek. Is there any way to figure it out ourselves?
Once again, thank you for all the input so far.
Best regards, Julian
