Hi, any assistance appreciated, I’ll be able to play around with it tonight.

This looks like another issue with late detection, but this time either with the dongle or the touchscreen. How is your touchscreen connected to the Raspberry Pi? Are you using a USB hub? What power supply do you use?

It’s connected via DSI straight to the pi. It’s powered using a carpihat pro 5. I have a usb hub too yes.

In the new version, we’ve improved screen parameter detection, so there’s a chance the new release will solve this problem. We’re working to make the new version available over the weekend, but at the latest, it will be released on Monday.

Hi I've got the same problem and no matter what I do there's no sound coming out of the hudiy_equalizer's rear channels.

pactl set-default-sink hudiy_equalizer_sink
pactl set-default-source echo_cancel_source

Running this results in this graph https://imgur.com/a/As0A8Px and even though the default sink (hudiy_equalizer_sink) is 4.1, fade is not available through the gui and only the front channels play sound.

Of course hudiy.conf has everything commented out and HUDIY has been started after setting up all the PipeWire nodes.

Hello, did you try to enable upmixing according to https://gitlab.freedesktop.org/pipewire ... e-Upmixing (try the PulseAudio part for now and set upmix-method to simple)?

To make fade control available in settings, you need to set the name of your remapped sink (surround51_to_41) in volumeSinkName

https://github.com/wiboma/hudiy/blob/ma ... n.md#sound

Also, the routing in qpwgraph looks a bit wrong. The optimal one should look like this:

hudiy_equalizer_sink -> Echo-Cancel Sink
Echo-Cancel Playback -> Remmaped sink
Remapped Sink -> CM106

Try to load modules in following order:
and please post the screenshot from qpwgraph with generated routing.

yes that was already set up.

yeah, that helped, thanks.

I figured out the problem - despite commenting out the config, somehow there were still nodes in PW before running those commands, idk maybe I just thought entering them was all I needed to do.

Anyway, Ive removed all the nodes manually and entered those commands. Now I'm getting a graph like this: https://imgur.com/a/p82gBOr (1st picture).

Unfortunately the rear channels still don't work unless I manually connect the front channels out of echo cancel output to both fronts and rears of the remap module (2nd picture). Then it works great but I don't want to do that every time I start my car up lol

Im still trying to figure out how to make that echo-cancel output to remap playback link stereo and for that remap module to do 2.0 -> 5.1 upmixing instead of 4.1 -> 5.1.

That looks like upmixing is still not enabled. Could you please post the config file and its location after doing steps from https://gitlab.freedesktop.org/pipewire ... e-Upmixing?

hi

I’ve started fresh on this with trixie and struggling to get my sound card to work, has anything changed?

I need to get upmix working and remix channels working if correct? Please can you sum up what’s needed. In trixie the file in pipewire pulse conf d is missing

@hudiy admin

Any advice appreciated as our old solution doesn’t work due to the changes to audio in the hudiy updates. How do i add these remix and upmixes.
