Audio problems with exported MP4 through VDI?

We've been making videos with Premiere CC and everything is going great.  We export them through encoder and all video and audio looks good.

We then host them on SharePoint and they play back fine.

We've now run into a problem with those viewing the videos on SharePoint but only when they are connected to a VDI.  Several colleagues are reporting that the audio is not working for them.  One said that when the sections of video where the onboard mic was used, they can hear that on VDI.  But then when someone - in the same video - speaks and our wireless mic was used, they said they cannot hear that through VDI.

When the video was edited in Premiere, nothing in the SW was changed - the footage was just dragged to the timeline  - both the footage with onboard audio and the wireless audio.  Everything can be heard in the SW as well as the exported file when played locally.

Keep in mind that this same video played back locally and on a computer without VDI works great.

I know this may be way off realm for this forum but wanted to just see if anyone has ever experienced this issue before?  If so, is it something I can do in Premiere or encoder?  To me, it sounds like some setting in the VDI (Citrix) environment, but that is beyond my knowledge base.

Any tips and help are appreciated.  Thanks.

    You have the SAME audio on L and R (see waveforms), so it doesn't matter. Pick one or the other, end result should be the same

    Don't overthink the process ;-)

    I should maybe explain what these effects are actually doing.

    Say you shot some video with your camera, using two microphones - shotgun on L channel and wireless on R. During editing, maybe you only want the wireless to be heard, so you would apply FILL LEFT WITH RIGHT. This takes the sound from R channel and completely replaces anything on the L channel with that from the R channel. So you end up with L and R being identical. Basically making mono sound from stereo.

    In your case, if indeed both L and R "sound" the same, but the phase is inverted between them, they cancel each other out when listening on a device with mono sound playback. By using the FILL effect, both channels will have identical content, no cancellation happening, and therefore sounds fine on mono playback device.

    Thanks

    Most likely a similar problem to this:

    I believe Richard is most likely correct on the cause. As for a "quick fix" try this - for the audio clips having issues, try adding either the FILL LEFT or FILL RIGHT effect. This will for instance take the content of the L channel and copy it to the R channel, so both are the same, then it should work. This worked for another forum member recently.

    Thanks
