Hello,
I recently installed Manjaro on a Razer Blade 14 (coming from a Stealth 13 with Linux Mint) and the sound quality and volume from a headset plugged into the 3.5" are atrocious / unusable.
The computer speakers work great, however, and via Bluetooth the same headset works perfectly.
I’ve played around in ALSAMixer and PulseAudio, the volume for the headset is set to 100% and is very quiet, and there is no bass at all (it sounds like an old phonograph). I don’t see anywhere else I can be looking, but I’m happy to provide any useful info.
Thanks!
