My audio system consists of two sources (1) Squeezebox Touch with EDO plugin and (2) Optical->COAX both into the Tone Board. Audio from both works fine and music from both sources through the tone board sound amazing. My only unfortunate issue is that the Squeezebox Touch has a habit of exclusively locking the Khadas USB port and hence does not allow music coming in through the COAX even when no music is playing on the Touch.
As USB is the priority input source, the only way to play music via the COAX is to physically unplug the USB and power via a USB-PD source
Not sure if it is at all possible but would be great if there was a way to change the input priority on the Tone Board (i.e. give priority to COAX instead of USB)?
Thanks for any replies or advice.
