HifiBerry DAC8x

Most probably you need to enable upmix feature in the PipeWire: viewtopic.php?p=1442#p1442

Also it might be needed to set proper volumeSinkName in main_configuration.json https://github.com/wiboma/hudiy/blob/ma ... n.md#sound

Hudiy detects number of channels based on sink information provided by the PipeWire.

it is working now after I tried a freshly setup Trixie with Hifiberry DAC8x. I'm not sure if my earlier Bookworm has too many qpwgraph file interrupted the setup. anyway, will try out if it works. here is what I did:
Driver: Add dtoverlay=hifiberry-dac8x to /boot/firmware/config.txt to enable the DAC8x.
sudo apt install alsa-utils
# For PipeWire setup
sudo apt install pipewire-audio-client-libraries pipewire-pulse wireplumber

Create: /etc/pipewire/pipewire.conf.d/99-hifiberry-dac8x.conf
copy these"

context.objects = [
{ factory = adapter
args = {
factory.name = api.alsa.pcm.sink
node.name = "DAC8x"
node.description = "DAC8x"
media.class = "Audio/Sink"
api.alsa.path = "hw:sndrpihifiberry"
audio.channels = 8
audio.format = "S32LE" # Or S24LE
audio.rate = 48000
}
}
]

restart Pi. go to desktop mode and right click the audio icon --> device profile --> enable Pro Audio.
then go to qpwgraph to remap the audio links as shown.
then in the hudiy_startup.sh: add this
qpwgraph --minimized --activated --exclusive saved_routing.qpwgraph &

I don't think it is because of the DAC8x issue somehow I get this udev thingy notice after I plug in my phone running Android Auto. I remember I don't have such during my early trial of Hudiy. however I get this a lot in OpenAuto Pro.
