Hi,
I have recently purchased the Allo Boss Player and have been playing it through a tpa3255 power amplifier using Volumio to adjust the volume. I’ve connected an Alps rk27 10k potentiometer between the Boss player and amp and am unable to hear any sound. Could anyone advise me if this is possible or if this setup is even supported in Volumio?
Check your connection between components one more time.
Thank you xlisec, I had damaged the output on the pcb, wired straight to the alps pins and it’s up and running. It appears 40 years of being a carpenter has left me with somewhat fat fingers!
