[SOLVED] pipewire: No sound in headphones

I have Microsoft LifeChat LX-3000 headphones (a really basic USB headset) and they work flawlessly with Pulseaudio. However, switching to pipewire (0.3.26 or 0.3.25) somehow breaks the sound output.

The only error in logs that I see is this one:

pipewire-media-session[1532]: The decibel volume range for element 'Speaker' (-2837 dB - -6 dB) has negative maximum. Disabling the decibel range.

It repeats four times when the headphones are connected.

The device is detected correctly though and pactl shows that everything is good:

$ pactl info
Server String: /run/user/1000/pulse/native
Library Protocol Version: 34
Server Protocol Version: 35
Is Local: yes
Client Index: 81
Tile Size: 65472
User Name: sgureev
Host Name: behir
Server Name: PulseAudio (on PipeWire 0.3.26)
Server Version: 14.0.0
Default Sample Specification: float32le 2ch 48000Hz
Default Channel Map: front-left,front-right
Default Sink: alsa_output.usb-C-Media_Electronics_Inc._Microsoft_LifeChat_LX-3000-00.output_analog-stereo
Default Source: alsa_input.pci-0000_00_1f.3.input_analog-stereo
Cookie: 8aa8:c90a

I use KDE and I can see graphical feedback on a volume regulator indicating that the audio is being played through the device, but no sound is actually coming out

Microphone works fine BTW ¯\_(ツ)_/¯

So far I tried:
1. Replacing all configs in /etc/pipewire/media-session.d with .pacnew ones
2. Maxing out everything in alsamixer on all the tabs for all devices
3. Rebooting ofc

Re: [SOLVED] pipewire: No sound in headphones

pactl list cards
pactl list sinks
pactl list sink-inputs 

during attempted playback?

Edit: Fix wrong command

Solved by updating pipewire to 0.3.28
