Got a PBP - batch(August/September) and the audio is not good(2 big issues)

[crazyquark]

Hello all,

I finally decided to get a PBP and I mostly love it but the audio is... not good.
First of all, here is what I did to try to get the latest software:
I got Two-Boot, installed Manjaro ARM generic 22.08 (XFCE), updated touchpad firmware(not sure it did anything).
Previously I had tried Manjaro ARM for PBP(22.06) as well as the KDE factory image(had some issues with Wayland).

Now here is the state of the audio, with the latest Manjaro and everything:
1. The popping and whine are still here: to clarify, if the audio module gets suspended it does an annoying pop sound - this can be worked around by not letting the sound suspend via wireplumber.
2. The whine from speakers - high pitch noise, whatever - this is can be reduced by getting the brightness of the display to max and can be removed by switching to headphones output(you will hear it in the headphones if they are connected)
3. The mic is just broken - 2 separate issues:
3.1 the internal mic picks up an enourmous amount of noise drowning out any useful signal - maybe tweaking some stuff in alsa would help - I am not sure yet.
3.2 plugging in a TRRS headphone does not allow using the microphone on the headphones, the port is just not there. Possibly an ALSO issue. I tried messing around with asound.state but no success.
bonus:
3.3 bluetooth audio also does not allow for mic use

Look, I love the PBP but audio... is a basic function of a laptop, I am open to fixing/hacking anything.
P.S.
I ordered a USB to audio jack adapter(mini usb audio card) to try to bypass the audio card entirely, maybe this will be a fix but... yeah, wish the onboard audio would work.
HELP !

I was nodding along in agreement until reading this. I have Sennheiser HD 350BT Bluetooth headphones, and they worked the first try. This is with Manjaro+Plasma. So I don't think the Bluetooth audio issue is universal.

Yes, I was able to get bluetooth audio/mic to work by switching profiles.
