Speaker volume control doesn't work by default on Lenovo Yoga 7 (AMD 7840hs)

[smaug----]

(Not sure which alsa-repo is the correct one for this issue, or is this perhaps a Fedora issue)
By default controlling headphone output volume works, but speaker output seems to be either muted or very loud.

The following tweak fixes the issue.

Same here, adding these lines to the conf fix the issue but they're erased on every updates of alsa, pretty annoying.

Omg, the latest update fucked up the volume again, this really needs to be addressed. The solution proposed by @smaug---- doesn't work for me, what works is

• edit /usr/share/alsa-card-profile/mixer/paths/analog-output.conf.common
• go down to [Element PCM]

it should looke like something like this, for me EVERY UPDATE removes the Element Master part :

[Element Master]
switch = mute
volume = ignore

[Element PCM]
switch = mute
volume = merge
override-map.1 = all
override-map.2 = all-left,all-right

Got the same problem and fixed it myself by automating the process, check it out here. @Gpinchon

I might submit a pull-request later.

I'm not quite sure if this is due to the kernel, but on 6.6 and 6.7 I don't need the fix anymore, also the tweeters work as well! Sadly, this breaks headphones. They're completely silent and have to be turned up in alsamixer.

Also mic volume with a headset connected controls mic boost instead of mic volume...

Is there an easy way to fix these paths, is it just an incorrect pinout? I found the HDA Analyzer but it's built for python 2 and I haven't set that up atm.

[smaug----]

Yeah, the headphones issue is why I need to stay on kernel 6.6.6. I think 6.6.7 broke it, but I haven't had time to investigate which change exactly.

[then4p]

It's fixable on those newer kernels. After you've connected headphones, just go into alsamixer and up the volume for the 'rear speaker'. Afterwards you can control the headphone volume normally. If you disconnect and reconnect the headphones it's busted again.

I really want to know where these connections are stored, but I haven't had any luck in the documentation so far and there's too many conf files in /usr/share/alsa-card-profile/mixer/paths

Also, interesting that something is happening between kernel 6.5 and 6.6. I found a parallel issue in another repo: tomsom/yoga-linux#3

[smaug----]

Unfortunately I don't see anything for "rear speaker" in alsamixer.

6.6.7 has this patch:

This issue is not related to alsa-lib. Use the kernel discussion mailing list - linux-sound@vger.kernel.org - for the further discussion.

The workaround from Gpinchon works for my Lenovo Slim Pro 7 (14APH8) #366 (comment) - for me headphones in alsamixer show up as 'bass speaker.'
