Has anybody had problems with SfB picking up audio from a mixer?  I have a Roland v-4ex that feeds an hdmi camcorder, a presentation laptop, and audio to a win10 pc via usb.  I confirmed that audio is getting to the laptop by recording the feed from the mixer. I can also see the audio levels jump in windows device manager.  Skype audio options sees the mixer and it is selected but the volume level bar is blank and does not jump when a person is speaking.  I've also tried it with a magewell usb card and the same thing happens. The pc sees the audio, Skype sees the card but audio isn't getting to it.

 

Thanks for any help  you can provide

We have this issue a couple of times as well. Skype would see the U tap box and use that and was fine but if we introduced a usb audio mixer it wouldn’t recognize it. I believe Skype has a built in audio “detector” that mixes down in the program. We had issues with audio cutting out as well on videos that had significant musical spots. It was like Skype was too smart, detected loud audio and turns it off. Strange behavior.

This is one of the biggest issues why we don't use Skype Broadcasts as much. The audio gain control used by the SfB client is awesome for dropping all the background noise in a regular meeting, but that is also exactly what causes sound passages to drop if you feed it from external sources.

As a test, feed some pink-noise to the SfB client and watch the audio completely disappear on the other side, after a few seconds.

We use some registry hacks that make the AGC less aggressive (link), but there is no way to fully disable it. There were rumors that a "new" SfB Broadcast client was being built, but have not heard anything on that lately. And now that "Teams" is the new SfB client, not sure what the future is for the the Broadcasting crowd :)

Here are some other threads where this same issue has come up... but to no avail:

I have experienced the same thing and I am beginning to think that Skype only supports audio on the left channel, not left and right. Do you have any thoughts on this?

Jeff

Sorry I do not have any additional information. I have tabled this project until broadcasts are available using Teams.

Replying to an old post, but we too found that only one channel (left I think) coming out of our switching equipment was 'heard' by Skype
