Hello oh wise one. This morning the magic has gone away… sob, sniff, bwahhhhh.
Resumed Tower as usual from its nightly slumbers, to be greeted with … no sound. I’ve inspected my
/etc/pulse/default.pa & confirmed that my previous edit remains intact, ie, that line remains commented-out. I issued [several times] the command
systemctl restart --user pulseaudio.service, but that did not help. Looking at the SystemTray volume widget, its analogue volume control is missing. Looking in
pavucontrol reveals this ridiculous status:
My mind is foggy atm; i can’t remember if today is the first or second Tower Resume since i applied the latest Testing Update, which took kernel from
5.0.2-2 … has this new kernel bump broken your fix? I shall keep working as-is for now rather than reboot, in case you might happen along & have some amended inspiration for this silly situation pls.
sudo journalctl --list-boots i see …

… so this is the 2nd not 1st Resume, ie, kernel cannot be the root cause otherwise sound should have failed with yesterday’s morning’s Resume, not today’s. Sigh.
Edit, later… Shassen rassen frassen… Pamac pulled a swifty on me, grrrr. Told me there was one  update available, Vivaldi-Snapshot, so i accepted it. Damn thing then snuck in a Pamac package update, & updated all my kernels, as well as doing V. Had other stuff to do, didn’t expect this, would not have done the update atm had i known kernels were included… tried to then get on with doing my other stuff [post-Pamac], but my resident Tower Poltergeist did not like that so it froze everything, forcing a damn inconvenient reboot. So now i’m back up & running the new kernel 5.0.3-1. Wonder what will happen with tomorrow morn’s Resume re audio.
