After upgrading to 20.04 my sound will cut out to total silence and then back after a second or less, no matter if using CD, audio file, video file or streaming. I noticed that with the sound settings window open, the Output Device will change from "line Out-Built-in Audio" to "Headphones-Built-in Audio" when the sound stops and then back to line out when the sound returns. I tried the command: systemctl --user status pulseaudio and get this output at the end: Jul 04 10:15:59 roger-desktop systemd[1502]: Starting Sound Service... Jul 04 10:16:15 roger-desktop pulseaudio[1516]: Failed to open cookie file '/ho> Jul 04 10:16:15 roger-desktop pulseaudio[1516]: Failed to load authentication k> Jul 04 10:16:15 roger-desktop pulseaudio[1516]: Failed to open cookie file '/ho> Jul 04 10:16:15 roger-desktop pulseaudio[1516]: Failed to load authentication k> Jul 04 10:16:18 roger-desktop systemd[1502]: Started Sound Service.
So I am not sure if it is working because when I enter: journalctl | grep pulseaudio I get: Jul 04 10:16:15 roger-desktop pulseaudio[1516]: Failed to open cookie file '/home/roger/.config/pulse/cookie': No such file or directory Jul 04 10:16:15 roger-desktop pulseaudio[1516]: Failed to load authentication key '/home/roger/.config/pulse/cookie': No such file or directory Jul 04 10:16:15 roger-desktop pulseaudio[1516]: Failed to open cookie file '/home/roger/.pulse-cookie': No such file or directory Jul 04 10:16:15 roger-desktop pulseaudio[1516]: Failed to load authentication key '/home/roger/.pulse-cookie': No such file or directory and nothing for when the sound stops.
