Sidetone mixer missing in pulseaudio/pipewire interfaces
Hi,
My headset Corsair Virtuoso has a mixer called sidetone in alsa which can be seen and set using amixer and alsamixer.
➜ ~ ✎ amixer -c3 contents

➜ ~ ✎ amixer -c3 scontrols
Simple mixer control 'Sidetone',0
Simple mixer control 'Mic',0
Simple mixer control 'Headset',0
➜ ~ ✎ amixer -c3 sget 'Sidetone'
Simple mixer control 'Sidetone',0
Capabilities: pvolume pvolume-joined pswitch pswitch-joined
Playback channels: Mono
Limits: Playback 0 - 23
Mono: Playback 17 [74%] [-8.00dB] [on]But it's not listed anywhere when it comes to pulseaudio and pulsewire. For example it's not listed when I use pavucontrol, Plasma audio settings, or kmix in pulse-audio mode. I tried to mess around with pipewire's alsa-monitor.conf by changing the acp and ucm values but the Sidetone mixer did not apear anywhere. I'm new to pulseaudio and pipewire and I'm trying to understand the relation between alsa and pipewire entities. Can anyone point me toward a correct direction how to investigate this further? Here is my pw-dump result if anyone needs to look at.

Re: Sidetone mixer missing in pulseaudio/pipewire interfaces
Pipewire/pulseaudio uses config files for logically mapping the most common controls together so that it's possible to provide profile distinctions for SPDIF or analog and the like and exposing a single volume control that adjusts the relevant HW controls as exposed by amixer. If you have a "non-standard" mixer control it won't be adjusted. But you can technically "add support" for controls like these by defining your own pulse/pipewire profiles.
This profile information for how to handle things as well as a few already existing adjustments in this regard are located in /usr/share/alsa-card-profile/mixer directory. The paths directory contains configs for how the HW controls are configured/accessed so you'd add a file to handle your sidewinder element there, checkout the analog-output.conf.common file for an extensive comment regarding the file format and possible options.
In the profile directory you then add a file for how the paths definitions map to logical profiles (e.g. an input only profile would mute all outputs, or in your case you'd have additional profiles that enable or disable the sidetone in the first place), here again, the default.conf contains comments.
once you have the files set up you'll need to add an udev rule so that pipewire applies a given config for the device in question e.g. /etc/udev/rules.d/91-pipewire-nvidia.conf
SUBSYSTEM!="sound", GOTO="pipewire_end"
ACTION!="change", GOTO="pipewire_end"
KERNEL!="card*", GOTO="pipewire_end"
SUBSYSTEMS=="pci", ATTRS{vendor}=="0x10de", ATTRS{device}=="0x10f0", ENV{ACP_PROFILE_SET}="nvidia.conf"
LABEL="pipewire_end"this is an example for adding an additional profile to a nvidia HDMI setup so that all monitors can be played back to independently.
See https://www.freedesktop.org/wiki/Softwa … /Profiles/ as well, the relevant logic here has been lifted into pipewire and should fundamentally work the same.

Re: Sidetone mixer missing in pulseaudio/pipewire interfaces
Thanks for the answer. Following your guidance, I've been studying the pulseaudio/pipewire and trying to understand pulseaudio and alsa entities correlation to create a proper alsa profile. As I mentioned before, I'm new to pulseaudio and pipewire so correct me if I'm mistaken in my conclusion.
If I understand correctly, pulseaudio tries to hide many details and as a result it uses a single volume control to adjust all "standard" hardware controls (mixer-control in alsa) exposed by alsa. Of course it uses alsa profiles for mapping the relevant "standard" mixers and do some heuristics to group them under one volume control. It seems the basic assumption in pulseaudio is that all mixer-controls only control the volume of a device. This assumption basically eliminate the possibility of controlling other aspects of the device using mixers exposed by hardware alongside the volume control in pulseaudio. In my case, the sidetone mixer-control doesn't control the volume of the device. It only controls how much of the mic input should be mixed to headphone output so we can hear what we're saying without shouting and this can't be achieved in software due to latency issues. If I'm not mistaken, as the result of this single volume control assumption, all of the accompanying software for pulseaudio, for example audio control panels, volume controls and mixers only support showing a single volume control per device. In this case the users must resort to use another solutions like using a different different mixer control software for example alsamixer in my case. Please let me know your thoughts on this.
