What to use as audio device for pHat DAC?

[davthomaspilot]

Will the script it work with this I2S DAC?

Found this feature request:

https://github.com/BaReinhard/Super-Simple-Raspberry-Pi-Audio-Receiver-Install/issues/115

So, I think this means I just choose HifiBerry DAC as the option for the audio device?

So, I can bluetooth connect from my Ipad to Pi Zero W with PHAT DAC, but no audio plays.

Before I ran the install script here, I could hear sound using speaker-test and aplay. But now I get messages about access denied when I try to do speaker-test and connection refused when I do an aplay.

When I do pactl list sources I see

bluez_source.A4_F1_E8_B6_2E_72.a2dp_source

but it's in the suspended state. Is that expected?

Didn't mean to close the issue. Not sure how to open. But, is anyone monitoring anyway?

Hi,

I want to use the phat dac too. But I just got them. Did you tried the method mentioned here?

#36

Or in short:

• install the i2c scripts from phat dac vendor
• choose "No sound card" during installation

[alexander480]

Run this command before installation
curl https://get.pimoroni.com/phatdac | bash

Reboot

Start installation

Select "No sound card" when promoted to select sound card

I've installed this repo waaaayy too many times on raspberry pis with pHat DACs, including just last night, so this definitely should work.
