Hi,

I try a RP3 + clone hifiberry PCM5122 compatible working with Volumnio.
Conf seems OK using dtoverlay=hifiberry-dacplus … no error on starting process Zynthian.
Hardware audio is :
dtoverlay=hifiberry-dacplus
-P 70 -t 2000 -s -d alsa -d hw:sndrpihifiberry -S -r 44100 -p 256 -n 2 -X raw

Headphones output sound OK but no sound with the audio card although recognise with aplay

Hi !

For everyone in my case.
My “no sound” was a optimisation of jack parameters
before :
-P 70 -t 2000 -s -d alsa -d hw:sndrpihifiberry -S -r 44100 -p 256 -n 2 -X raw
after :
-P 70 -t 2000 -s -Rd alsa -d hw:sndrpihifiberry -S -r 44100 -p 512 -n 3 -X raw
Latency optimisation regarding rpi power cpu.

Thanks to myself !
