Valve Index microphone stopped working

[[CPEx] MotoFckr9k]

The microphone on my Index is not working anymore since the SteamVR update 1.6.9. I have a hunch that it doesn't have anything to do with the update, but that is the time it stopped working.
The microphone shows in alsamixer and pavucontrol, but doesn't actually record anything.
Pavucontrol doesn't show it recording anything and it doesn't record in VRChat.

I have tried:
restarting ALSA
restarting PulseAudio
restarting the computer
reconnecting the Index multiple times
reconnecting the Index to different USB controllers

I am running:
Linux Mint 19.1 (Ubuntu 18.04 based)
ALSA k4.18.0-20-generic
pulseaudio 11.1
Nvidia 418.52.07 (audio output works)

EDIT:
I actually just saw a bug report regarding this exact issue: https://github.com/ValveSoftware/SteamVR-for-Linux/issues/215

I was just about to say: Seems to be a known issue with Steam VR. It's the same for me (Ubuntu 18.04 using rhe customised kernel as described on the github page).

On a similar note: Is your camera on the index working? I'm using SteamVr 1.6.10 but it didnt work on 1.6.09 either.

I don't know how I would use them in SteamVR, but they don't seem to work in Cheese.

If you go to settings->Camera it says "Camera not available" for me. i'm just wondering if its the same for everyone else.

Since this seems to still be a problem, I'm going to risk necroing this thread to help people find a/the solution:

In /etc/pulse/daemon.conf change
"default-sample-rate = XXXXX"
to
"default-sample-rate = 48000"

then create file
~/.config/pulse/daemon.conf
and add
default-sample-rate = 48000
to it.
Then restart pulseaudio with pulseaudio -k.

You only need one of these files to have the setting.
I made the change to '/etc/pulse/daemon.conf'. It got my mic working.

Good to know that worked for you. I made the change to the first file expecting it to work, and after much hairpulling I found there was a second daemon.conf file in .config and adding it there as well worked for me.

Confirmed.. My mic also stopped working and changed the default sample rate to 48000 in /etc/pulse/daemon.conf to 48000 and that fixed it. Now if I can find a thread on the broken "Desktop" support in 1.21.x (works in 1.20.4)...
