[AudioI] No sound on icecast2 stream

[Phillip Fox]

Hello all,
I'm trying to setup a local icecast stream using a Raspberry PI CM4 installed on the Compute Module 4 IO Board with the AudioInjector Stero card installed.

I think I've configured the card as outlined in github and I think I have darkice and icecast running properly because they are generating a stream, but there is no sound in the stream.

I think the problem might be with the device I've configured as my source. Running aplay -L I get the following output:
hw:CARD=audioinjectorpi,DEV=0

    audioinjector-pi-soundcard, AudioInjector audio wm8731-hifi-0

    Direct hardware device without any conversions

plughw:CARD=audioinjectorpi,DEV=0

I've tried using the following device options in my darkice config with no luck:
hw:CARD=audioinjectorpi,DEV=0

plughw:CARD=audioinjectorpi,DEV=0

sysdefault:CARD=audioinjectorpi


I've used a headphone line out from my phone and from a small amp (which is plugged into a pre-amp) using both the RCA and the headphone line in.

Is one of those listed devices the right option, or is there something else I can do to test the problem? 

Thanks for any help!
