Cm6206 Output

[alex124.rh]

Can you please share this card with me and i will just use that for ease. Thanks. Couldn’t find any that work like that. Did you get music from all 4.1 ch without upmix on

[hudiy]

We bought this card in a local electronics store. When connected via USB, it appears as “C-Media Electronics, Inc. CM106 Like Sound Device.” It didn’t require any additional configuration other than switching the profile to 4.1.

If you want to enable upmixing manually in PipeWire, according to the documentation we shared earlier, you can use the parameters channelmix.upmix, channelmix.upmix-method, and channelmix.lfe-cutoff. You can set them, for example, in the $HOME/.config/pipewire/pipewire-pulse.conf.d/hudiy.conf file like:

Code: Select all

stream.properties = {
    #node.latency          = 1024/48000
    #node.autoconnect      = true
    #resample.quality      = 4
    #channelmix.normalize  = false
    #channelmix.mix-lfe    = true
    channelmix.upmix      = true
    channelmix.upmix-method = psd  # none, simple
    channelmix.lfe-cutoff = 150
    #channelmix.fc-cutoff  = 12000
    #channelmix.rear-delay = 12.0
    #channelmix.stereo-widen = 0.0
    #channelmix.hilbert-taps = 0
    #dither.noise = 0
}

thanks, i was going to buy one like this anyway actually as the one i had is known for audio clipping.

It looks similar but different casing, so i will give it a go. Was yours unbranded?

[alex124.rh]

i bought one and 4.1 reports FL FR RL RR and FC on the channel map, can you let me know if you set yours to 4.1 and analog stereo mic or just 4.1. can you let me know your output of pactl list sinks please, so i can compare.

when you set it to 4.1 are you getting subwoofer settings in hudiy

[alex124.rh]

Hoping for some help on this! It seems alsa drivers have the mapping wrong. Since its such a complicated fix mayne you can allow hudiy to support and recognise the 5.1 profile, so that the sub works and wont break the volume control. if it ignores the centre thats fine as long as it could accept 6ch, allowing these soundcards to work as they all have the same issues.

Please do see my previous message, I hope to see your output in terminal to see if your card is correct on 4.1

We can add setting the volume for front-center, but that would be more of a workaround. The better approach would be to create an issue on the PipeWire GitLab (https://gitlab.freedesktop.org/pipewire ... /-/issues/) and investigate why your sound card’s channel mapping is broken and how it can be remapped or fixed.

[alex124.rh]

Thanks for the info. I will compare to mines.
If you could add it that would be great, as I dont think I will get any other solution as easily as that. It’s not just my soundcard, it’s every one I tried from amazon that was available.

Let me know if you can add that fix to the upcoming release? Is there a date for planned update.

[hudiy]

Try this config to remap the channels from 5.1 to 4.1 and please confirm if balance/fade works with your sound card.

1. Switch profile of your sound card to 5.1

2. Replace content of $HOME/.config/pipewire/pipewire-pulse.conf.d/hudiy.conf with:

Code: Select all

pulse.cmd = [
  { cmd = "load-module" args = "module-remap-sink sink_name=surround51_to_41 master=alsa_output.usb-0d8c_USB_Sound_Device-00.analog-surround-51 channels=5 master_channel_map=front-left,front-right,rear-left,rear-right,lfe channel_map=front-left,front-right,rear-left,rear-right,lfe remix=yes" }
  { cmd = "load-module" args = "module-ladspa-sink sink_name=hudiy_equalizer_sink master=surround51_to_41 channels=2 channel_map=front-left,front-right plugin=hudiy_equalizer label=hudiy_equalizer control=0,0,0,0,0,0,0,0,0,0,0,0,0,0,0" }
  { cmd = "load-module" args = "module-echo-cancel aec_method=webrtc aec_args=\"voice_detection=0\" source_name=echo_cancel_source sink_master=hudiy_equalizer_sink" }
]

stream.properties = {
    channelmix.upmix      = true
    channelmix.upmix-method = simple
    channelmix.lfe-cutoff = 150
    channelmix.fc-cutoff  = 12000
    channelmix.rear-delay = 0.0
}

adjust master name if needed.

3. Set volumeSinkName to "surround51_to_41" in main_configuration.json (https://github.com/wiboma/hudiy/blob/ma ... n.md#sound)

4. Add & (run in background) at the end of line with hudiy_run.sh in /etc/xdg/labwc/autostart to not block wireplumber and avoid race condition with PipeWire clients like Hudiy during the remap:

Code: Select all

$HOME/.hudiy/share/hudiy_run.sh &

5. Restart the Raspberry Pi

PipeWire should handle the routing like:

clients (like Hudiy) -> hudiy_equalizer_sink -> surround51_to_41 (upmix if needed to 5.1 done by PipeWire) -> sound card (with front-center cut-off).

[alex124.rh]

Hi there, I did as instructed and managed to get it to like the volume sink, it’s no longer broken, however now i have 0 audio output at all.

Let me know how to proceed. Thanks again for the help
