I just wanted to try that, only to find out I can already suddenly change the volume using alsamixer and I have no idea how that happened
Maybe some changes require multiple reboots to work? But which change....
Code: Select all
slave.pcm "softvol" #make use of softvol
pcm "dmix" #redirect the output to dmix (instead of "hw:0,$
name "PCM" #override the PCM slider to set the softvol vol$
Oh well, at least that works
. Now for the popping, which always happens once and always at the same time audio starts coming out of the speakers.
Next up: Finding a way to receive FM (and maybe AM) radio with RDS and have the audio routed through Adafruits DAC. Since it doesn't seem to have an audio input, I don't think that's gonna be easy since most FM-receiver breakouts have a 3.5mm jack as output which also (when cable/headphones plugged in) functions as an antenna.
will work, but I don't see any details about hooking it up to a RPi in the hookup guide. Or maybe a RTL-SDR dongle will do, but I do not know if a Pi Zero W has the cpu-power for that.
