I just followed the instructions mentioned on this link: https://gist.github.com/Brainiarc7/8ff198a5ac3f0050f68795233c4866d0
Of note is that for /etc/pulse/daemon.conf , the following changes must be made (with your preferred text editor): (a). For 5.1 channel sound, set: default-sample-channels = 6 (b). Ensure that enable-lfe-remixing is set to yes. (c). The default channel map option for 5.1 audio should be set as: front-left,front-right,lfe,front-center,rear-left,rear-right To turn timer-based scheduling off add tsched=0 in /etc/pulse/default.pa: /etc/pulse/default.pa load-module module-udev-detect tsched=0 Then restart the PulseAudio server: $ pulseaudio -k $ pulseaudio --start I am using the same speakers mentioned on the link: Logitech Z506 Speaker system and using analog 5.1 audio settings. I will check again today to see if this problem re-appears and will report back. If this does not work, i will remove hdajackretask as suggested by Kai-Heng and see if that makes a difference. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1879182 Title: Sound cuts off and back on randomly during online streaming of videos To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1879182/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
