Only 2 out of 4 speakers are used on my laptop

My new laptop has 4 speakers at roughly 4 corners (judging by the outlets, and sound produced when boots into windows). After base installation of archlinux. I installed "alsa-utils", "pipewire", "wireplumber", "pipewire-audio", and "pipewire-pulse". Initially, no sound through any of them at all. I installed "sof-firmware" and "alsa-firmware", and only 2 speakers can be heard. Because of this, the sound is really low. And if I turn the volume up, the sound will first be distorted and then hearable.

I ran "speaker-test -c 4". I got an error said 

speaker-test 1.2.8

Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
ALSA lib pcm_dmix.c:999:(snd_pcm_dmix_open) unable to open slave
Playback open error: -2,No such file or directory

This is resolved by setting ./.asoundrc file to

defaults.pcm.card 1
defaults.ctl.card 1

Then, I can hear white noise from Front Left and Front Right, but not from Rear Right and Rear Left.

At some point, I tried switching from pipewire to pulseaudio, but the problem persisted so I switched back.

Also, This is the feedback from "aplay -l"

I searched around, but can't find a similar case. I'm not familiar with sound systems in Linux. In my old setups, sound just works so I didn't pay much attention. I would appreciate any suggestions on how to debug this.

Re: Only 2 out of 4 speakers are used on my laptop

The majority of sof firmware stuff is very rough around the edges sadly and it wouldn't surprise me if this was the norm currently. Which system/laptop is this exactly? What output do you get from 

aplay -L
pactl list cards
pactl list sinks

Re: Only 2 out of 4 speakers are used on my laptop

The laptop model is Thinkbook 16p Gen4. It's quite new, so I would assume the support is not that good.

I'm suspecting it's related to the "audio.channels = "2"" or the "channel map" thing. But I can't find how to configure it for pipewire. For pulseaudio, according to PulseAudio Example, it seems I can set "default-sample-channels=2" to "default-sample-channels=6" in "/etc/pulse/daemon.conf". Does that mean I should give pulseaudio another try?

Re: Only 2 out of 4 speakers are used on my laptop

If you think sof is the problem, I can switch to snd_hda_intel. I initially got snd_hda_intel to work with some tricks I found here (The two models use the same ALC287 chip). But I still can only get the 2 speakers working.

I made the switch from snd_hda_intel to sof  because I found from the arch's ALSA wiki that, for new laptop models, I should use sof-firmware. But that didn't help.

Re: Only 2 out of 4 speakers are used on my laptop

You should generally use sof for new hardware, pipewire or pulseaudio are irrelevant if it doesn't work on a ALSA level either (the channel map setting in pulseaudio should also not be overly relevant if the alsa-ucm-conf properly announces 4-channel support, which it doesn't in this case, so if anything this is up to a alsa-ucm-conf setup issue/and or system firmware not announcing the verb table properly). FWIW the proper test for that would be 

speaker-test -Dhw:1,31 -c4

maybe also post/check 

amixer -c1

Re: Only 2 out of 4 speakers are used on my laptop

Yeah just from this there's logically little way to make this work, one thing you could test is whether opting for the older snd-hda-intel driver works better by creating a file in /etc/modprobe.d/switchHDA.conf 

options snd_intel_dspcfg dsp_driver=1

and rebooting

Re: Only 2 out of 4 speakers are used on my laptop

Yeah, I come to realize this is not a configuration thing, but some bugs due to lack of supports of the hardware.

I tried setting "options snd_intel_dspcfg dsp_driver=1" and then

In this config, I have the "analog-surround-40" for the cards but the sink still is "audio.channels = "2"". And if I run "speaker-test -c4", I still only have the same two working speakers and the prompt line says

speaker-test 1.2.8

Playback device is default
Stream parameters are 48000Hz, S16_LE, 4 channels

Also the mic is gone.

I read the around 1k posts from the kernel bug report. It turns out this thing is twofold. Firstly, the audio chip is actually ACL3306 which is wrongly recognized as ACL287 by the kernel. ACL3306 has no linux driver, but people from the posts made a reverse-engineering version of it. This patch made it to the kernel at around ver. 5.X.X so my kernel (6.3.1) should have it. However, my laptop's audio chip is labeled as ACL3306-CG (see here). I have no idea if the two is the same one and if it can work with the driver. Then, Lenovo puts extra level of awfulness by using a "smart amplifier" for the speakers, which requires a driver. This driver is not provided for linux, and we don't know if there will ever be one. Without this diver, you may only have the two speakers running and have a low volume.

From what I learned from the Lenovo's forum, this issue affects multiple newer models from Lenovo, at least these with the "smart amplifier". The arch wiki said the audio is supported but it is actually not, at least not fully supported. This Thinkbook 16p Gen4 of mine is also labeled as supported. Maybe we could consider modifying this to avoid misleading newcomers.
