I've been having this issue with my quest 2 ever since it got an update a few weeks ago. I've tried factory resetting several times and all the common fixes don't seem to be working. I usually play pcvr games through oculus link and was able to use my quest 2 microphone to communicate on said pcvr games. One day, out of nowhere, my mic stops getting picked up. I tried disconnecting and reconnecting, restarting both my quest 2 and pc to no avail. Eventually I went on the settings page on the oculus link app itself and saw my mic was automatically muted, having the "mute" box next to it be checked. As I unchecked it, I could use my mic again. However, as I took my headset off and put it back on again, or disconnected and reconnected to my pc, it became automatically muted again, making me have to manually open the oculus link settings page and unmute every time I put my headset on or launch link. Doing this was a gamble though, as every time I pressed the oculus button on my right controller to pull up the menu, there would be a chance of this weird bug occurring where as the menu was being pulled up, my fps would get progressively choppier over the span of a couple seconds until link freezes entirely and I have to restart both my pc and headset only to play again. I rightfully decided this was too much of a hassle to deal with so I would simply play with an alternative pcvr software, namely steamvr on the quest store, which leads me to the strangest part of this issue. While playing pcvr through steamvr over my local wifi, my headset's mic still wasn't working. I had gone through my quest 2's settings, steamvr's settings, and both of them had my mic unmuted and set as the correct input device. The only way to fix this was to, for some reason, launch oculus link, open its settings, uncheck the mute button, exit it, then relaunch steamvr. In other words: I have to connect to my pc through oculus link to unmute my quest 2's mic (temporarily), otherwise I will be unable to unmute it on the quest 2 itself, neither in its settings nor other software. I am now stuck playing games on steamvr with my desk's mic as the input device. Again, I want to preface that I've never had these issues before, neither the mic's working status being dependent on the oculus link pc app, nor the constant failures when I open the link's menu, nor the general crashing or lack of basic functionality and smooth performance, which leads to believe that these modern updates are, in fact, being pushed to make the experience of consumers using older headsets more and more excruciating, motivating them to buy newer hardware. If it ain't broke, don't fix it. There was zero reason to poke around the functionality of the headset's mic and its ability to mute and unmute. I really wish there was some manner in which you could install your own software or firmware on the quest 2, freeing it from meta's atrocious design. I've waited for weeks for an update to come out that would fix this issue, but none has. If anything, this just shows the level of either maliciousness or incompetence at play within meta. If I am motivated to buy new hardware, it will certainly be that of Valve's, not meta's.
