I am running Ubuntu 19.04 on my HP Omen Obelisk and have noticed the the sound is much softer and lacking punch (even at full volume) when compared to Windows ( Im dual booting). Im running a simple stereo set up.
On the windows side Im running the Realtek HD audio that HP auto downloads. Device manager also lists Realtek R Audio
card 0: PCH [HDA Intel PCH], device 0: ALC1220 Analog [ALC1220 Analog] Subdevices: 0/1 Subdevice #0: subdevice #0
I have tried turning on amplification via Sound and pavucontrol, with very little luck. The sound becomes crackly after that point.
Any ideas what else I can do ?
