[SOLVED] No audio and bluetooth on fresh KDE Wayland with LTS

I just installed Arch Linux manually with the Linux LTS kernel. I downloaded the pipewire package. I tried the forums and the wiki but neither my sound is working nor my bluetooth.
I am a beginner, I have an Nvidia 4050 mobile GPU with AMD CPU. The system is an ROG Strix G17 (2023). Please let me know what to do.

Try this:

sudo pacman -S sof-firmware

Re: [SOLVED] No audio and bluetooth on fresh KDE Wayland with LTS

the LTS kernel is a year old in terms of HW support, if you're wondering about HW support, don't pick the LTS kernel.

For audio you're most likely missing sof-firmware, for BT have you seen and what are your findings of: https://wiki.archlinux.org/title/Bluetooth

If neither help, post the link you get from

sudo journalctl -b | curl -F 'file=@-' 0x0.st

The bluetooth issue has now been resolved after I did

 systemctl start bluetooth.service 

Audio works over bluetooth too.

As for the audio in general, I did install sof-firmware package and rebooted but that didn't fix it.
The link I get from the "sudo journalctl -b | curl -F 'file=@-' 0x0.st" is http://0x0.st/X5zm.txt

Re: [SOLVED] No audio and bluetooth on fresh KDE Wayland with LTS

The card is technically detected correctly, what output do you get from

sudo fuser -v /dev/snd/*
aplay -lL
amixer -c0
pactl list cards
pactl list sinks

while attempting to play back and sound not working?

Oh wait it isn't

and online references suggest this should be mostly fixed on 6.7+ kernels --> don't use LTS if you worry about HW support.

Re: [SOLVED] No audio and bluetooth on fresh KDE Wayland with LTS

You are right, I have installed the mainline Linux kernel and the issues have fixed themselves. It was a hardware support issue.
