What I’m trying to do:
- Output: Hifiberry Amp
- Input: Delock
However, when I boot Volumio with both adapters connected, I can no longer play audio:
Error Failed to open "alsa" [alsa]; Failed to open ALSA device "hw:2,0": Device or resource busy
I tried to disable the I2C dac, reboot and enable it again, but the problem persists as long as both adapters are connected. Connecting the Delock after booting will not break playback and the line-in option appears in the sidebar, but it appears no signal is picked up.
