thank you Linux for giving a damn about Bluetooth headphones

For context, LDAC is one of the few wireless audio codecs stamped Hi-Res by the Japan Audio Society and its encoder is open source since Android 8, so you can see just how long Windows is sleeping on this. I'm excited about the incoming next gen called LC3plus, my next pair is definitely gonna have that.

I'm still wondering how to make my headphones work on pop os without crackling

You will not believe this. Solution was adding a line in some config file.

Are you thinking of the standby timeout? Cause I get static on my speakers on any and all distros when no audio is playing. It always happens after 5 seconds of silence. Kinda infuriating that I have to do this on EVERY SINGLE DAMN INSTALL.

For Pulseaudio:
Quickfix (until reboot):

sudo su
echo 0 > /sys/module/snd_hda_intel/parameters/power_save

permanent fix is to add the line:
options snd-hda-intel power_save=0
to the file /etc/modprobe.d/alsa-base.conf

For pipewire:
create folder /etc/wireplumber/main.lua.d/ if it does not exist
if you had to create it yourself just copy over the file from /usr/share/wireplumber/main.lua.d/50-alsa-config.lua
otherwise it probably is there already then just edit it
pretty much at the bottom there is a line that says "session.suspend-timout-seconds"
uncomment it and set its value to 0
then reboot

Pretty sure this used to be the fix for me:

( scroll down to comment about default.pa and tsched=0 )

But I just checked my default.pa and it is stock values, so I am not sure anymore

When experimenting, setting cpu governor to performance also helped.

Used to have that problem on suse, it was something to do with pulse but I can't recall, solution was in ArchWiki

Ubuntu user, for me I've always had to disable/delete the voice dispatcher, that usually does it.
