Hi, i installed Fedora in my new yoga 7 pro, but only the bottom speaker seem to work. The audio card i see with aplay -l is ALC287. I already tried the solution suggested in English Community-Lenovo Community (yes i know these are for intel version but i tried). Has anyone any clue to make all 4 speakers work.
Welcome to 
The Lenovo Thinkpad Yoga 7 Pro has had a rough history with some of it’s audio configurations.
Please post your inxi -Fzxx here for us to see the hardware specs, also we’ll post some links to thread regarding the Yoga models. . .

Removed intel
Just to be sure, you might try confirming that those parameters were correctly parsed and applied by reading the corresponding files under /proc. I.e., do these two commands show that the parameters are in effect?
$ cat /sys/module/snd_hda_intel/parameters/model
and
$ cat /sys/module/snd_intel_dspcfg/parameters/dsp_driver
P.S. The Arch wiki suggests a slightly different options line – options snd-sof-intel-hda-common hda_model=alc287-yoga9-bass-spk-pin (Lenovo Yoga 9i 2022 (14AiPI7) - ArchWiki). Maybe try that variation?
Hello, the two cat commands return:
alc287-yoga9-bass-spk-pin,(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null)

I tried your second link but nothing changed.

It looks like there might be a patch in the pipeline:

Can you edit your post and paste it into </> preformatted text
We have other users with similar devices, wondering if it will help them ? it’s a Yoga 16ARP8
I’m just searching kernel.org (i.e., something like site:kernel.org 14AHP9) and looking for recent patches that might be related to specific hardware. I don’t see anything “recent” matching 16ARP8 though. There are patches from Feb. of this year, but it seems likely those would be in the current stable kernel by now if they worked. I didn’t really dig into the threads. If you have a better idea of what you are looking for, you might want try searching kernel.org and skimming the posts that match there to see if you can gain any insights about the current state of the situation.

The Arch wiki states that having the right firmware installed/available is also an important part of the equation for getting some sound cards to work. Do you have the alsa-sof-firmware package installed?
I edited that to add the preformatted text tags (available with the </> button on the toolbar of the text entry screen) so the on-screen formatting was restored and the data is much more readable.
Please post text that you copy & paste using that method.

Ok so you think i have to wait and the issue will be fixed?
About the second question: yes, i have alsa-sof-firmware installed.
I’m not sure. The patch only shows one line being added to patch_realtek.c.

That added line (the one that starts with +) appears to just do what you are trying to do manually – apply the yoga9-bass-spk-pin PCI “QUIRK” mode if hardware 0x17aa 0x3891 (Lenovo Yoga Pro 7 14AHP9) is detected. The implications would be a) it is very likely that the yoga9-bass-spk-pin mode does need to be set for your hardware and b) you would no longer need to apply that setting manually once that upstream patch reaches the stable kernels that end users run.
The patch doesn’t appear to be doing anything with regard to the “dsp_driver” setting though. Have you tried setting yoga9-bass-spk-pin but leaving dsp_driver at its default value?
If that still doesn’t work, dsp_driver=3 (SOF) looks like an interesting option: SOF Linux Driver Architecture — SOF Project 2.9.0 documentation. I have no idea if it would work though.

Update
Ok guys, today i tried again modifying the settings of the snd.conf with the settings of Lenovo’s post and forum’s ones and after selecting the sound card with F6 in alsamixer, two new settings showed up: one about bass speakers, and one about front speakers. I can control the levels and in fact they turn on and off the upper pair of speakers and the bottom one. Incredible. Then i tried removing the sda.conf to see if the alsamixer options effectively disappear. To my surprise, they were still there! Can it be something related to Fedora updates i did this afternoon?

Wow, you have some interesting findings. Could ity be possible to provide more details on the process, The Yoga’s are very problematic with that Audio configuration.
- modifying the settings of the snd.conf with the settings of Lenovo’s post and forum’s ones
- after selecting the sound card with F6 in
alsamixer, two new settings showed up - one about bass speakers, and one about front speakers

It’ll help many Bothans
