Hi DomieMic65,
All the usb soundcard drivers are included in Linux as part of ALSA. The only way to upgrade is to upgrade the kernel. This is not recommended as it will probably break RuneAudio.
The only other good way to upgrade drivers is by upgrading the linux-firmware package, see here for details:
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/about/ There is no guarantee that this will fix the problem, but it relatively safe and should eliminate some potential causes.
You can upgrade it by logging in via SSH and running this command:
pacman -Sy linux-firmware
If you need more help please supply some more information, preferably your debug.
