I have a (relatively) old USB sound card, EMU-0404. It's official drivers (for Win/Mac) were not updated for years (last Windows official support is for Win 7, with 64 bit drivers in beta release)
Today I (accidentally) discovered that it is identified in Ubuntu 18.04 in the audio settings - as 'Emu-0404' with all the analog and digital in/out. That's great, but the sound quality is bad, there are noticeable digital artifacts.
Is there a way to make it work properly?
