So, I updated and my startech usb sound device (https://www.startech.com/en-us/cards-adapters/icusbaudio2d) doesn't work anymore. I plug it in, and the lights come on, and there's a hissing in the ear phones, and after a while they get hot. I never had hot ear phones before.
I don't see the device in pavucontrol or in the plasma system settings.
Attached is what alsamixer looks like.

I tried a similar more compact/defaultish config, but it didn't work.

Hello,
Have you tried setting your USB sound card to default?
sudo nano /etc/asound.conf
And added this to select card1:
defaults.pcm.card 2
defaults.ctl.card 2
Restart system
**********
Personally, I removed the pulseaudio packages except one: libpulse.
I installed qastools which offers a nice and very practical mixer :
sudo pacman -Sy qastools
Then I listed my audio cards:
cat /proc/asound/cards
0 [HDMI ]: HDA-Intel - HDA ATI HDMI
HDA ATI HDMI at 0xfce60000 irq 96
1 [Generic ]: HDA-Intel - HD-Audio Generic
HD-Audio Generic at 0xfc900000 irq 98
I created/modified /etc/asound.conf
And added this to select card1:
defaults.pcm.card 1
defaults.ctl.card 1
Restart system
I think the problem is that the drivers are not loading or that the updates dropped functionality for my device. So, it wouldn't matter what I put as default. I just don't know what packages did that.
While waiting for a specialist to answer you:
What kernel are you using? Maybe you can try another one?
I assume you looked for clues in:
sudo dmesg
and
lsmod

Maybe I'm reading it wrong, but it doesn't make sense that it appears to think it's an input device?
Have you tried the LTS kernel? And the xanmod (https://forum.artixlinux.org/index.php/topic,3703.0.html) kernel?
Ok, I installed the LTS kernel, and removed the "regular" kernel. And now it sees the devices, but there's no sound and the headphones get hot. I guess it's entirely possible that it did break coincidentally at the same time I updated, I just remain doubtful that's the case.
Wired headphones like AKG?
Does it still work on other devices?
A malfunctioning driver can cause hardware damage. :(
This is bad. It's indicating abnormally high electrical current running through the headphones. Can you test them on another computer?
