Hi.
I have an Audient iD14, which is a USB class compliant audio interface. The sound output is very loud on the right and super soft on the left. I am running Lubuntu 16.04 with ALSA only. No PulseAudio.
I have run some diagnostic commands. Would appreciate help interpreting the output.
I'm trying to understand the problem, so I can find a solution.
