RecalBox Portable with speakers - Adafruit Speaker Bonnet

[SheerAutomation]

Hello,

I'm building a custom portable recalbox unit. I'm looking to use two speakers (3W 4 ohm). I bought the Adafruit I2S 3W Speaker bonnet hoping this was an easy speaker addon. I don't want to have another power supply supplying a power amp board. I tried to install using the instructions, but I'm assuming because this is a buildroot and not a linux distro, that might be the disconnect?

"curl -sS https://raw.githubusercontent.com/adafruit/Raspberry-Pi-Installer-Scripts/master/i2samp.sh | bash"

Has any one got this board to work with recalbox or know of a way to get these speakers to work with Raspberry Pi 3 + RecalBox?

Thanks in advance.

@sheerautomation Looks like you need to add dtoverlay=hifiberry-dac to the /boot/config.txt and change the default alsa configuration file. But using at least the overlay should work, you should find the sound card in ES

@substring Your Awesome! Adding it to the boot config then selecting it in ES gives me sound through ES and for the games. The only thing it doesn't allow is the sound outside of ES. So when RecalBox loads, theres no sound until you enter ES. I'm fine with that at this point because I only care about the sound in ES but was wondering if there was a way to enable it outside ES as well?

Thanks again for all the help.

@sheerautomation that would mean allowing alsa configuration before the splash video. No plabs on doing that for now

@substring No problem. I prefer not to have sound before ES anyways.
Thanks again for all the help.
