[Bug 1872196] Re: 5.1 audio does not work

[Jouni Mettala]

Thank you for taking the time to report this bug and helping to make
Ubuntu better. This bug is reported against grub-installer. Grub-
installer doesnt' have anything to do with sound.

https://wiki.ubuntu.com/DebuggingSoundProblems
describes how to report audio bugs.

Therefore I am closing this bug as invalid.

Ubuntu 20.04 is released next week. http://releases.ubuntu.com/
It is more efficient to report bugs against new version of Ubuntu.

You can submit new bug report preferably using 20.04 Focal Fossa
via ubuntu-bug -s audio

** Changed in: grub-installer (Ubuntu)

Title:
  5.1 audio does not work

Status in grub-installer package in Ubuntu:
  Invalid

Bug description:
  Hello,

  I am using Ubuntu 19.10 with 5.1 surround speakers. 
  I tried to configure 5.1 surround, but it still doesn't work. 
  I also installed Pulse audio. 
  Here is the info about my soundcard:
  # aplay -l
  **** Lista PLAYBACK de dispozitive ****
  placa 0: PCH [HDA Intel PCH], dispozitiv 0: ALC892 Analog [ALC892 Analog]
    subdispozitive: 0/1
    Subdispozitiv #0: subdevice #0
  placa 1: NVidia [HDA NVidia], dispozitiv 3: HDMI 0 [HDMI 0]
    subdispozitive: 1/1
    Subdispozitiv #0: subdevice #0
  placa 1: NVidia [HDA NVidia], dispozitiv 7: HDMI 1 [HDMI 1]
    subdispozitive: 1/1
    Subdispozitiv #0: subdevice #0
  placa 1: NVidia [HDA NVidia], dispozitiv 8: HDMI 2 [HDMI 2]
    subdispozitive: 1/1
    Subdispozitiv #0: subdevice #0
  placa 1: NVidia [HDA NVidia], dispozitiv 9: HDMI 3 [HDMI 3]
    subdispozitive: 1/1
    Subdispozitiv #0: subdevice #0

  See 'lscpi -v' output attached.

  I tried the test below and instead of center speaker, right speaker
  plays two times and the subwoofer do not work at all.

  Please let me know what other details you need.

  Thank you!
