Patch not working on Lenovo Yoga 7 Gen 7 AMD (14ARB7)

[64kramsystem]

I'm opening this issue just for reference (in case somebody with the same device is looking for a solution).

I've tried to force the bass speaker fix on my device (Yoga 7 Gen 7 AMD (14ARB7)), but it didn't yield any effect:

# rebooted after this change
#
sudo tee /etc/modprobe.d/snd.conf <<CONF
options snd_intel_dspcfg dsp_driver=1
options snd_hda_intel model=alc287-yoga9-bass-spk-pin
CONF

This has been tested on a v6.0-rc7 kernel, without any patch (actually, I've applied the mic fix, which I think should not be in conflict), since I've seen that the patches in this repository have been upstreamed.

Wow, it works 🤯 Many thanks 😄

Here's a script, for anybody who wanted to just copy/paste. It assumes that tlp is installed and enabled.

# to run as root

apt install -y i2c-tools

cat > /etc/tlp.d/99_fix_yoga_speakers.conf << 'CONF'

Do you still run it with the snd.conf modprobe? Or have you removed that section before running these steps?

I've just run it successfully, and I think this workaround works in isolation; I don't think I've previously applied other related changes - I've rolled back the snd.conf change after I found that it didn't work.

I was, rather, surprised that tlp is preinstalled; I think that on Ubuntu they started to preinstall it only recently (verified on 22.04 as dependency of the desktop package).

This workaround needs a refinement - the ic2set command needs to be rerun after resuming (works on resume from hibernation; didn't test from suspend):

cat > /lib/systemd/system-sleep/fix_yoga_speakers << 'SH'
#!/bin/bash

if [[ $1 == "post" ]]; then
  /root/bass-speaker-on.sh
fi
SH

chmod +x /lib/systemd/system-sleep/fix_yoga_speakers

So, I didn't set any modprobes.
I reinstalled TLP.
apt install tlp
edit: /etc/tlp.conf
systemctl enable tlp
systemctl start tlp

Still important!
The speaker may be driven with too much power!
Therefore set another register, which reduces the power/volume. Better safe than sorry.

disable sound-powermanagement without tlp.service

/etc/modprobe.d/alsa-base.conf
options snd_hda_intel power_save=0 power_save_controller=N

[64kramsystem]

disable sound-powermanagement without tlp.service

/etc/modprobe.d/alsa-base.conf options snd_hda_intel power_save=0 power_save_controller=N

This works; note that the customboot service is still needed, including the tlp dependency (After=...).

disable sound-powermanagement

The mentioned https://github.com/tomsom/yoga-linux/ repo is probably a better place to discuss problems relating to AMD Yogas. Closing this as I'm not able to fix for a device I don't own.
