The obvious temporary fix: downgrade kernel, nvidia and nvidia-utils to previous versions.

I can confirm the same issue, and fix.

I have the same issue too... In pulseaudio they are marked as "unavailable"

I confirm issue, downgraded kernel to 5.4.15 fixed it. I did not change the Nvidia driver, it works with 440.48.02
Comment by loqs (loqs) - Tuesday, 04 February 2020, 13:50 GMT
Is the issue still present under nvidia 440.59-1?
Comment by Thomas Kuschel (oe1tkt) - Tuesday, 04 February 2020, 14:03 GMT
@loqs The problem does not seem to be the graphics driver NVIDIA, but the kernel 5.5.1-arch1-1 - Now, I've tried the nvidia 440.59-1 with that kernel, but it does not fix it.
Comment by loqs (loqs) - Tuesday, 04 February 2020, 14:10 GMT
What difference is there in the logs between 5.4 and 5.5 e.g. dmesg / journal
lsmod
sudo fuser -v /dev/snd/*
aplay -lL
pacmd list-cards
pacmd list-sinks
Comment by Peter Åberg (kvt2000) - Tuesday, 04 February 2020, 14:10 GMT
O yes, it seems to be a kernel- not nvidia issue. And unfortunately nvidia 440.59-1 does not resolve the problem.

please edit the  FS#65361  to kernel issue only

Maybe this is a help for debugging: differences b/w kernel 5.4.15 and 5.5.1
There are twice as much detections for inputs as in the former kernel, and it's mapped to card0 instead of card1:
journ_5.4.15__5.5.1 was generated with
journalctrl -b > journal_5.4.15 (under linux 5.4.15-arch1-1)
journalctrl -b > journal_5.5.1 (running linux 5.5.1-arch1-1)
cut -c23- journal_5.4.15 > journ_5.4.15
cut -c23- journal_5.5.1 > journ_5.5.1
diff journ_5.4.15 journ_5.5.1 > journ_5.4.15__5.5.1

lqos, no I haven't.
looks like heftig is rolling a v5.5.1-arch2 with a fix: https://git.archlinux.org/linux.git/log/?h=v5.5.1-arch2
Comment by frost work (frostwork) - Tuesday, 04 February 2020, 18:39 GMT
linux-5.5.1.arch2-1 + nvidia-dkms-440.59-2 from testing fixed the issue.
thanks for the quick update!
Comment by Thomas Kuschel (oe1tkt) - Tuesday, 04 February 2020, 19:42 GMT
It works as usual again with linux-5.5.1.arch2-1-x86_64, thanks also for the quick repair!
