Ahhhh…. that’s the whole reason I bought the hifiberry and setup M2P – I wanted to switch between the line-in port and streaming music from my NAS. 🙁
I know Volumio supports the line-in port, but only on their top paid plan.
I might switch to plan B and use an external amplifier and use a hardware switch to select the input feed to the amp
Many thanks for all your help – at least I know not to try any more – I could have wasted even more hours getting frustrated!!
