[SOLVED] Wired headphones not shown in audio output. No sound.

[aq74i]

Hullo,
Am a beginner to Linux and most computer things.

This is a Macbook13,2 model running Linux Mint (6.1.0-1013-oem kernel). The speakers themselves don't work, wired headphones don't appear in audio output.
I did manage to get a bluetooth connection to a「sony pxc 550 ii」and there was sound, though intermittent, very scratchy, and with weird old radio-ish static like noises. [edit: After all the attempts to fix the detection of the wired headphones but failing, the sound quality of the wireless headphones seems to have been fixed..I don't know what happened. Am still trying to figure out how to get the wired connection working though.]

Is there anyway to get wired headphones to work?
Sorry and thank you.

ALSA also didn't look like it does on pictures in tutorials.

Have tried fixes from here and stack exchange/overflow(?), but none of them work.

Also tried sudo evtest, then plugging out and in the wired headphones, but there was no change in the terminal text.

another edit: There was another thread with a similar issue, and they got wireless bluetooth headphones to work too. Don't think the wired headphone issue got resolved though. 【viewtopic.php?t=317609】

Also, adding the results for ~$ dmesg | grep snd

Even if my problem doesn't get solved, this information might help someone in the future, so am going to just update to this post if there's anything noteworthy.

Followed the instructions on this and installed pipewire successfully. However, bluetooth headphones became significantly crackly in sound quality, and the wired headphones were still not picked up. Have a suspicion that the headphone jack just isn't working.

Because this computer also uses Codec: Cirrus Logic CS8409,
attempted François Romain's fix in the uppermost comment, which is copy pasted below.

Today, the computer surprised me by making a few notification beeps out of its speaker, and upon checking sound settings in the applet down at the task bar, speakers being recognised and displayed (there was previously nothing at all).
Plugged in wired headphones and it recognised the headphones. Can listen to things now without any issue. Sound feels slightly louder than in the past, when this computer was running macOS, but that was solved by tweaking volume and amplification settings.
