[New component] HiFiBerry Sound Card & OnOff SHIM

[pabera]

Add components folder to installation and docs. First component is hifiberry sound card
#2168

[s-martin]

I followed this guide:
https://www.hifiberry.com/docs/software/configuring-linux-3-18-x/

I used miniamp

[pabera]

Yes. i will update the script to have all these options.

[s-martin]

I just remembered that the RFID reader configuration can trigger Python dependencies or custom shell scripts, see https://github.com/MiczFlor/RPi-Jukebox-RFID/blob/future3%2Fdevelop/src%2Fjukebox%2Fcomponents%2Frfid%2Fconfigure%2F__init__.py#L16

Could be worth it to think of a similar mechanism for soundcards or other hardware, if they need a script.

Isn't phoniebox 3 / future3 based on the bookworm debian images? so the config.txt should be in /boot/firmware/config.txt and not /boot/config.txt -> this took me a while to find out why hifiberry-dac was not loaded.
see the first paragraph in https://www.raspberrypi.com/documentation/computers/config_txt.html

You are right with the changed path for bookworm.

There are a few changes to bookworm which just came up and haven't been addressed yet (e.g. network manager). We have to look into this.

Strange that this worked in my case.

Thanks a lot for your input. Sorry to hear that you struggle to find initially.

Isn't phoniebox 3 / future3 based on the bookworm debian images?

future3 supports both versions, Bullseye and Bookwork.

I did test these changes on my current Pi Zero 2. The suggested Debian version (by Pi Imager) for this hardware is still Bullseye. But it seems to be true that this is different for Bookworm. I will take care of this in another commit.

@team: We will have to adapt our documentation as /boot/config.txt is referenced in different places.

Although I couldn't find any info that the hardware is the same as hifiberry, the I2S PCM5102A DAC soundcard seems to need the same configuration: #1886 (comment)

[s-martin]

We should also add how to customize the shutdown command, so the Phoniebox shutdown is used (that's why I was working on pbc.c and run_rpc_tool.py).

I could add something tonight.

[pabera]

Preferably, add it directly to this PR
