Is2 Audio Bonnet and Raspberry Pi 4

by hepaestus on Mon Oct 25, 2021 12:20 pm

I am tryin to get the IS2 Audio bonnet to work with a rasbperry pi 4 model B and a 7" Touchscreen.

I have tried everything in the tutorial to get the bonnet to work but it is not responding as far as I can tell:
https://learn.adafruit.com/adafruit-i2s ... y-pi-usage

I can sometimes hear a faint popping sound during reboot, but that is the only time any audio is produced.

I have Raspian Running on the RPI and I am trying to use Plex Media Player eventually as the audio software.

Code: Select all | TOGGLE FULL SIZE
$ uname -a
Linux Thelxiope 5.10.63-v7l+ #1459 SMP Wed Oct 6 16:41:57 BST 2021 armv7l GNU/Linux


Any clues as to what I need to do to get this working?
Thanks,
P.

I thought this bonnet was more of an audio amplifier but it it not. :(
It makes no sense to use this since the RPI 4 has a stereo output.
The output is NOT enough to drive most speakers but its fine for headphones.

The i2s audio quality will be much higher on the 3.5mm stereo jack using this bonnet than on the default analog Pi4 jack. You also have the option to add dual stereo RCA jacks for more traditional home amplifier connections.
