USB Sound card issues

Hi There,

I am running Ubunthu on a Le Potatoe. I am using a ORICO USB sound card that has the CM108 chipset.

I have set it up to read audio through the mic port and loop back to play it through the headphone port live. My issue is that if the aux connected to the mic port is fully plugged in, I get white noise, but if I pull the aux cable (mic port) about half way out I get the correct sound in both ears.

Does anyone have some advice on what is happening here and how I can get this to work fully plugged in?

Thanks
Andrew

This is the cable I am using for the mic port. The headphone port works perfectly.

Does this happen when you plug it into a PC? If so, it’s the device plug contact ordering.
