Sound not working Focal Fossa Ubuntu 20.04

发布于 2020-07-22 06:18:18

I have been using ubuntu 20.04 recently and have a HP pavillion laptop with B&O speakers. However i am not able to hear any sound. though, Bluetooth is working fine.

I have tried many solutions such as :

*sudo apt purge timidity-daemon

*sudo alsa force-reload

*sudo apt install pavucontrol and running pavucontrol.

None of the solutions have worked for me yet.

EDIT: Later I assumed it to be a kernel bug and say a solution using the following commands:

sudo add-apt-repository ppa:kaihengfeng/fix-lp1869819
sudo apt-get update

after that i have tried reinstalling pulseaudio. And now bluetooth devices just after getting connected are automatically disconnected, do not play any sound either.

Finally, after surfing a lot through the net and reading about options of alsa for NVIDIA aound controller I got the following solution

2 files are to be changed

  1. /etc/modprobe.d/alsa-base.conf
  2. /etc/modprobe.d/blacklist.conf

Changes in File 1.

  • open the file using root
  • add the following line to the bottom of the file options snd-hda-intel dmic_detect=0
  • save and exit the file

Changes in File 2.

  • open the file using root
  • add the following to the bottom of the line blacklist snd_soc_skl
  • save and exit the file.

Reboot and Enjoy with the restored sound!
