Question / Help Microphone Using 2i2 No Longer Works

The microphone I use is plugged into a Focusrite Scarlett 2i2 Audio Interface, and it used to work flawlessly with OBS. Now it fails to recognize any microphone input, but will still recognize the rest of the audio output (game/desktop audio) from the same device.

When I start recording/streaming, both the mic and desktop audio level meters flicker, then the mic shows no more activity.

I think that 0.623b was the last working version for me, or maybe the one before it (but it is no longer available for download). I use either x264 or QuickSync depending on my needs, but the microphone usage doesn't come back in either one right now.

My logs don't show any errors involving audio.

Hmm, maybe there are some audio errors after all. The "analyze" function that you can use didn't catch it though.

Do you have "Use Mic QPC Timestamps" enabled in Advanced settings?

Also, can you post a log from a longer recording attempt? That was only a few seconds long.

It says it's set to "line in" for your mic, just verifying whether or not that's intentional. It may just be set to the wrong device. It doesn't have anything to do with the version because audio code was not changed in recent versions.

As for leads, we can't really get leads, we can give you theories (such as the line in thing above), but we can't really solve user problems remotely.

In my experience, the only times when a mic has ever truly failed to work is when: a.) the system is having DPC (deferred procedure call) issues, which is extremely rare, or b.) when the mic or input actually fails in terms of hardware.

All the other times when people have reported mic not working have simply been because they configured OBS incorrectly (wrong device selected, accidentally muted, accidentally enabled push-to-talk), or configured windows sound settings incorrectly (for example leaving exclusive mode on, though it will show an error for that usually).

Had a feeling. There really needs to be a visual indicator for it so people know they have it on when in the main window. Thanks for clearing that up.
