Pimoroni DAC SHIM - timbo22 - 09-25-2021

Hi all,
I have got hold of one of these
https://shop.pimoroni.com/products/audio-dac-shim-line-out
I intended to replace the PHAT CAD that I have successfully been using in my system. Based on the reviews i assumed it was a simple drop in with some minor config changes. I just cannot get it to work. I have tried both PHAT DAC and HIFIBERRY DAC named device and dt overlays. I have added gpio=25=op,dh to /boot/config.txt.
I have even resorted to a full fresh install. The good people at Pimoroni even swapped my original for a replacement in case of a damaged board.

in every case i can go back to the PHAT DAC and hear audio.

here is a screen grab

hope someone can help.

Tim.

RE: Pimoroni DAC SHIM - the_bertrum - 09-26-2021

I have one of the mono amplifier versions of those on pi Zero in an old kitchen radio and it works fine with the HIFIBERRY DAC selected. I didn't need to mess about with adding anything in config.txt either.

Not much help I know, but my experience says the device should "just work" ™.

RE: Pimoroni DAC SHIM - Tim Curtis - 09-26-2021

I don't see anything suspicious in the logs. I'd prolly remove out the line below.

gpio=25=op,dh

You might try settings ALSA output mode to "Direct (hw)" in Audio Config.

HDMI audio is selected yet the dac is i2s ?

RE: Pimoroni DAC SHIM - Tim Curtis - 09-26-2021

Look in dmesg to see if the i2s mapping is successful.

Below is what a success case looks like.

Code:
pi@rp2:~ $ dmesg | grep i2s

[    6.284777] asoc-audio-graph-card soc:sound: allo-cs43130 <-> fe203000.i2s mapping ok

pi@rp2:~ $

If there are errors then most likely some sort of hardware or connector issue.

RE: Pimoroni DAC SHIM - DRONE7 - 09-26-2021

Just to check (because it has happened on several occasions ) you have software volume selected.... have you adjusted the volume control on the mainMoOde player page ?

Code:
