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 ?

This is what AlsaMixer is set to

  • Does it have a sub-woofer or 4 speaker system? – WinEunuuchs2Unix May 3 '19 at 21:47
  • It has a subwoofer. from the digital out port of the pc, I use a 3 way splitter to the sub woofer, which sends it front left and right speakers. – ubuntububuntu May 3 '19 at 22:00
  • also WinEunuuchs2Unix it has a 3.5mm audio port, with which I use a 3 way splitter to send sound to the main, center and rear – ubuntububuntu May 4 '19 at 1:08
  • Thanks for clarifying the statement: "Im running a simple stereo set up." – WinEunuuchs2Unix May 4 '19 at 2:45

You need to install qasmixer and look at the master volume of your card . Set "show device selection" under view menu . As you will see Ubuntu 19.04 sets the alsa volume to a minimum level after start up. Restore that and go blast full .

  • I just installed Qasmixer and see that all the volume is set to 100%. – ubuntububuntu May 9 '19 at 22:38
