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)?
Unfortunately, I am hoping to use the Tone Board with two input sources (usb and coax) but have a need to change the priority from the usb (default setup) to coax. Would you know if that is at all possible? Thanks.
Let’s say, if you had a vim board (as a power supply for TB), then I fully admit your scenario. Here you need to understand from which device you will take control of TB
By the way, if you also have a vim board, then theoretically you will have 3 sources.
And in fact, what turns out, the source that is needed, we leave it on, and those that are not needed are turned off.
Hi Vladimir, thank you again for the prompt reply.
I am only using the Tone board as a standalone DAC (without VIM) and have only two sources.
Unfortunately, one for the sources (Squeezebox Touch connected via USB) holds on to the USB even when it is placed in standby (via remote).
In this case, I suggest you separate the power supply through the pins of the board according to the circuit, and then I think it will be easier to control your sources.
I no longer have Squeezebox to test out. However, my Archive linux has no problem to switch between coax or usb. Do you have the last version of Squeezebox? I may setup a quick one tomorrow to try out.
