Plexamp RPi Limit Bit & Sample Rates to Vintage DAC

interesting problem … Plexamp only sees the SPDIF HAT (which supports a wide range of bit depth and sample rate) as your output device, and it’s not aware of the DAC limitations further downstream

you should be able to create a ~/.asoundrc file to force the SPDIF HAT to use format = S16_LE and rate = 44100

(updated: try the contents below for your ~/.asoundrc file … then reboot the Pi, select “Default” for the Plexamp audio output, and you should be good … i also have an Allo Digione here, this seems to work … i’m sure there are other ways to do this)

pcm.!default {
 type plug
 slave {
 pcm "hw:CARD=sndallodigione,DEV=0"
 rate 44100
 format S16_LE
 }
}
