Volumio with Adafruit I2S 3W Stereo Speaker Bonnet

by neilhendrick2 on Thu Oct 12, 2017 3:54 pm

Hello,
I have set up a Raspberry Pi 0 W using the latest version of Volumio (2.285) https://volumio.org/. And I have added the Adafruit I2S 3W Stereo Speaker Bonnet for Raspberry Pi https://www.adafruit.com/product/3346

So, I have turned on the Volumio setting in Playback Options for I2S Dac (ON), but I cannot determine how I should set the other options. There is no specific choice for "Adafruit I2S 3W Stereo Speaker Bonnet". I have tried to select various settings in this section and the result sometimes crashes and reboots the raspi, or alternatively just does nothing.

What should i select for Output Device?
What should i select for DAC Model?

Should I change other Playback options such as DSD Playback mode?
thanks for your help,
Neil

PS: I did do some testing and I am able to run sound through the DAC and hear it from the speakers using the following commands. These all work fine:

We don't know anything about volumeio, so don't have any suggestions to offer there.

The information about making the I2C amplifier talk to ALSA is in this part of the tutorial:

https://learn.adafruit.com/adafruit-spe ... y-pi-usage

Hopefully something there will look close enough to one of the volumeio settings to be useful.
