Microphone issues with Nvidia Shadowplay Recording

[redBadger]

I'm using Nvidia Shadowplay (I think they call it Share now) and the quality is great but my microphone is registering as Stereo when it's a mono microphone. Therefore, the result is gameplay that is good audio but my voice is coming out of the left speaker only. The reason is that it thinks it's a stereo mic, but it's only picking up the mono signal and therefore summing it to the left.

The only solution I was able to find was to change the Default Format in Recording Devices > Properties > Advanced > Default Format and change it to 1 channel over the default 2 channel. However, windows is being an ass and won't let me change it off 2 channel at all.

Is there any third party audio application or some other workaround that can force windows to sum my audio to mono? I've used OBS and it is able to do this just fine (however I'm not a huge fan of OBS right now as it's recording quality looks like complete ass) so I'm not entirely sure what else to do other than to record my voice separate from the gameplay, which I'd rather not do.

Thanks!

I'm having the same issue as well, in recordings I constantly hear electric static noise on the right channel which forces me to edit the videos in mono. I talked with the devs at one point on the Nvidia discord and all he said was "check your drivers and use DDU" which obviously didn't do shit as it's a fault with the way the software mixes the mic. It worked two months ago perfectly fine too, why they had to change that is a question to me.

I'm currently trying virtual audio cable to set a link from my mic input>left channel>virtual input but I can't figure out how to do that and if it will cause huge buffer delays.

For most it's from using an XLR mic or other high quality mono-mic through a preamp or interface, which causes windows to derp and not register it as a mono mic. That's the issue i'm having specifically

Had the same issue as you, ended up "fixing" it using virtual audio cable gymnastics and a second program (Dxtory) for specifically audio and Nvidia Share for video. Synced up audio and video with handbrake. While Dxtory is excellent for audio because it can record a bunch inputs separately and supports lagarith lossless if you wanted some really tight recording, but it's a pain in the ass to setup and run consistently.

The issue's been around for years, but Nvidia is too brain dead to fix it by allowing a stereo > dual mono feature for XLR interfaces.
