I tested the PPA. It doesn't help. If anything, it might make things a bit worse.
Also, I can now confirm that I spoke a bit too soon in comment #19 when I said "linux-image-5.4.0-32-generic after removing kernel command line pcie_aspm.policy=powersupersave --> seems better so far". That configuration does seem a bit better, but exhibited the problem again a few times just now. I'm not even sure this is a userspace problem. A week or two ago I ripped out pulseaudio and the rest of the ALSA userspace stack and replaced it with the packages from Eoan. That was on an older kernel but it didn't help. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1879401 Title: [XPS 13 7390 2-in-1, Intel Icelake HDMI, Digital Out, HDMI] sound rarely works To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1879401/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
