I'm having trouble getting a Hifiberry Amp2 working.
System is Volumio 2.599.
This system has been running a Hifiberry Digi for several years. I decided to make it a self-contained system so I've switched to a Hifiberry Amp2. I can't get it to make a sound into my speakers.
I've set the Playback Options to Dac: HiFiBerry DAC Plus, and the Output Device to the same. All other settings are the default ones. The system starts, is playing, but I'm getting no sound. The green D1 and D2 leds on the Amp2 light up.
I also have an choice of "snd_rpi_hifiberry_dacplus as an output device, I can't select it, though.
My devices look like this. Note that I can switch to the USB DAC and all is good.
