As asked by @Hui Wang, I have created a separate bug #1880571 for my problem on focal fossa and run apport-collect. As the data collected by apport showed that timidity was running I have uninstalled timidity and this seems to have fixed the problem: audio output was immediately restored, and after each of three reboots (the last of which after removing "options snd-hda-intel dmic_detect=0" from /etc/modprobe.d /alsa-base.conf), audio output was available right after logging in.
So my problem really seems to be a bug in timidity. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1864061 Title: PCI/internal sound card not detected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1864061/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
