Max volume is lower then Stock os

I think this could be fixed with a filter chain but I am struggling to get it setup (pipewire is confusing 😭)

[ghost]

add this to /etc/pipewire/pipewire.conf.d/

    context.modules = [
        {   name = libpipewire-module-filter-chain
            args = {
                node.description =  "Boost Filter"
                media.name =  "Boost Filter"
                filter.graph = {
                    nodes = [
                        {
                            type = builtin 
                            name = mixer 
                            label = mixer 
                            control = {
			   	"Gain 1" = 3.5
				"Gain 2" = 3.5
                            }
                        }
		
                    ]
		   inputs = ["mixer:In 1" "mixer:In 2"]
		   outputs = ["mixer:Out"]
                }
                capture.props = {
                    node.name = "boost.sink"
                    node.passive = true
		   media.class = Audio/Sink
                }
            }
        }
    ]

wpctl set-default <sink's id>

@samueldr is something that I should make into a pr ? At least until its understood why the audio is quiet

[toast003]

Did some research and I think these files make the speakers loud enough, although I haven't tested it yet

[toast003]

Took a look at modules/steamdeck/sound.nix, and environment variables are set up with the location of the files I linked earlier, but they don't seem to be taking effect

Maybe putting them in a package (making them show up in /run/current-system/) might fix this?

I've noticed that SteamOS 3.5 Preview release increases volume on my Deck significantly.

What solved the issue for me was taking a backup of ALSA settings with alsactl --file asound.state store under SteamOS 3.5 (or under NixOS right after installation on top of SteamOS 3.5) and then restoring them under NixOS when the max volume eventually becomes lower with alsactl --file asound.state restore.

I believe it's also possible to tweak setting for acp5x sound card manually using the alsamixer.

Stock SteamOS 3.5 settings are the following:

alsactl settings backup: asound.state

alsactl --file /home/pongo/asound.state restore gives me the following on NixOS

alsa-lib main.c:846:(execute_sequence) exec '/bin/rm -rf /var/lib/alsa/card1.conf.d' failed (exit code 1)

In case anyone else also hits this, what worked for me is running the command in a container to then manually copy the resulting ctl-remap.conf to /var/lib/alsa/card1.conf.d/.

alsactl --file /home/pongo/asound.state restore gives me the following on NixOS

Oh, totally forgot about it, as a workaround to make alsactl work I've also created symlinks for /run/current-system/sw/bin/rm and /run/current-system/sw/bin/mkdir at /bin

[pongo1231]

Is that file perhaps something that should be shipped by default if jovian.devices.steamdeck.enableSoundSupport = true?

[K900]

Please test #187

[pongo1231]

Works on my end. After deleting /var/lib/alsa/card1.conf.d/ctl-remap.conf, applying #187 and rebooting the volume is still as it should be.

[toast003]

#187 doesn't seem to change the max volume for me

[K900]

Try running spa-acp-tool -c 1 spr 1

[toast003]

That did it!
It doesn't seem to persist reboots tho

[K900]

Should now survive reboots (after #187).
