interest in getting Codec Zero to play nicely with PipeWire?

[arrjay]

didn't necessarily want to drive by with a blind PR, so I figured I'd start here.

is there any interest in providing an ALSA UCM config so that PipeWire can be used to reconfigure that outputs for common use cases? I've actually got the config over in my fork at https://github.com/arrjay/Pi-Codec/tree/master

This provides for profiles configuring a single audio source and sink selection - you can chose inputs of [AuxIn Mic MicJack] and outputs of [AuxOut Speaker] - that is, these profiles:

$ pw-dump |jq -r '.[]|select(.type == "PipeWire:Interface:Device")|select(.info.props."alsa.card_name" == "RPi Codec Zero")|. as $parent|.info.params.EnumProfile[]|"\($parent.id):\(.index):\(.name)"'
49:0:off
49:1:HiFi (AuxIn, AuxOut)
49:2:HiFi (AuxOut, Mic)
49:3:HiFi (AuxIn, Speaker)
49:4:HiFi (AuxOut, MicIn)
49:5:HiFi (Mic, Speaker)
49:6:HiFi (MicIn, Speaker)
49:7:pro-audio

pinging @pelwell and @popcornmix as they understand this all much better than I do.
IIRC the only reference that we have to this repo is from https://www.raspberrypi.com/documentation/accessories/audio.html#extra-codec-zero-configuration

I read this as a poll of interest. Most smart people would avoid doing anything with ALSA unless forced to at gunpoint.

yeah - this was along the lines of "I wrote this so I didn't have to think about alsa, just set the profile on my desktop"

the Codec Zero might be the most interesting hat, audio routing wise. everything else just has outputs
