In the Christmas spirit I need your urgent HELP!!!
Lightshowpi.org is a sound and light application for the RasPi. (Flashing Christmas lights to music.)
To improve sound quality, I installed pHAT DAC.
I’m running it on a Pi Zero with Stretch Lite. Works perfectly.
I installed the pHAT DAC, and it too runs perfectly. Nice strong sound from my speaker.
The problem: when I run the two together, I get the error: alsaaudio.ALSAAudioError: Device or resource busy [sysdefault:CARD=sndrpihifiberry]
There is nothing else running and I’ve lost 4 nights sleep, 5 kg weight, and most of my hair trying to figure it out. Even the help forum at lightshowpi raised their hands in despair.
Please, please, please, will someone look at their config file
and tell me IS THERE ANYTHING THERE THAT MIGHT CAUSE ALSA TO GIVE ME THIS ERROR? (Note, I changed GPIO pin 1 (BCM 18) in their default setup because I know the pHAT needs it).
Please save my Christmas!
