Belana sound not outputting audio

Product support

1

Hi, I was following the tutorial on the website below, in order to use my raspberry pi zero w as a bluetooth receiver for my hifi. Whilst I am able to see the device as an option for bluetooth and airplay, there is no audio output. I think what makes this a bit more tricky is that the pi zero needs a DAC in order to connect a 3.5mm jack. In the tutorial it recommends adding a custom configuration: BALENA_HOST_CONFIG_dtoverlay with a value of hifiberry-dac. But I’m still not getting sound output. The DAC I am using is PCM5100A from: Audio DAC SHIM (Line-Out) — Pi Australia

Hi

Just to confirm you are not using a HiFiberry DAC, but have added that to the config. Is that right?

3

Can you check the list of supported DAC boards, and their config variable in the table given at Audio interfaces - Home
I think if I understood your setup correctly, that’s the only thing that needs to change.

Let us know how it goes!

I don’t think it’s a hifiberry, but from the website it says to specify that in the dtoverlay. I have put a quote from the website below if it helps:

Alternatively, if you’d rather not install all the Mopidy stuff, you can set Audio Amp SHIM as your default Alsa device in Raspberry Pi OS by adding the following lines to your /boot/config.txt file:

dtoverlay=hifiberry-dac
gpio=25=op,dh
