Thanks in advance for the help 
When I boot, audio is very quiet. I set PC volume to 120%, turn the speakers up to 90%, and can faintly hear my 90s lofi beats youtube video. If I suspend the computer, then wake it, the lofi beats permuate my soul and shake my house; it is super loud. I can return the PC volume to 50% or so, with the speakers at 25%.
I would like to make it so the audio functions correctly when the system turns on, rather than requiring me to boot, suspend, and resume.
The fact that the volume fixes after the PC has suspended was only realized today; I feel like it is a vital clue, but I have no idea where to look next.
Audio devices:
lspci | grep -i audio
00:1f.3 Audio device: Intel Corporation Comet Lake PCH cAVS
01:00.1 Audio device: NVIDIA Corporation GA102 High Definition Audio Controller (rev a1)
The issue is with the āIntel Corporation Comet Lake PCH cAVSā device; HDMI works as advertised. Headphones also work as expected, even if plugged into the onboard audio. Itās only the rear line out that has this issue.
I have reason to believe this isnāt just a Manjaro issue; I had the same problem with my previous install, OpenSUSE
Things Iāve tried:
- Going into aslamixer and making sure all channels are up
- This is what is recommended in basically every post I can find; dozens of them
- Using pavucontrol to do the same thing
- Using hdajackretask to change the line out to be registered as a āheadphoneā
Iām in a dual boot environment, and the audio on the other operating system is always loud enough.
Other outputs that might be helpful:
