I have a USB SteelSeries 9H with their own soundcard. It used to work by default on 16.04, but after the upgrade they do not anymore.
When I plug them in and execute cat /proc/asound/cards I get
0 [PCH ]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0xd3710000 irq 31
1 [Headset ]: USB-Audio - SteelSeries SC2 USB Headset
SteelSeries SteelSeries SC2 USB Headset at usb-0000:00:14.0-3, full speed
I uninstalled alsmixer and pulsaudio, I tried running alsmixer and set the headphones (they are visible there) to be used default, but I get
cannot load mixer controls: Invalid argument
Under the Sound option in Ubuntu, the headphones are not visible at all. Put if I plug any other headphones via jack (not USB) they work properly.
Nevertheless, if I plug them in with dmesg --follow running, I can see the system detects them. Log below

Does anybody has any suggestions about what I can do to fix the problem?
lspci -nnk | grep -A2 Audio,aplay -l, andpactl list short sinks? Please also make sure that the relevant audio channels inalsamixer(terminal) orgnome-alsamixer(GUI) have their volume turned up and aren’t muted. Thanks.
