device list duplicates

[steven30]

i have an echo connected to one amp through 2 amp inputs.

one input in through the amp direct input , called aux.

the other runs through my blusound device so that I may get the benefit of the dac.

i need to do it this way becasse blusound has no api for my alexa.

problem is.... in the devices list they both show up as 
"lr spotify".  any ideas?
