I'm trying to bring in a remote guest via Zoom into vMix using Virtual Audio Cables for the audio and keep getting a crackling sound over that cable. I've searched the forum but have not found an answer to this question. I'm new to vMix (just started using version 20 as a trial) but have been using Wirecast for about 10 months. As always you can reach out to with additional questions about this process, or anything else tech related to your show at Phill圜AM.Hi. We’ve got a whole tutorial on advanced screensharing for clip playback in Streamyard using VLC so be sure to check that out if you're going to use this audio loopback for Streamyard. VLC Player is a program that you can set audio outputs for independently which is extremely useful for screensharing video clips into Streamyard without messing up the rest of your sound. Instead, leave Zoom/Streamyard feeding directly to your headphones and set either the system overall, or the specific application you’re sharing, to output to that Multi-output device. This is because you would wind up sending everyone on the call their own audio right back on a slight delay and that will really mess with them. For one, you’re pretty much never going to want to set your Zoom or Streamyard speakers to that Multi-output device or to the VB-Cable directly. So that’s the bulk of it! There a few more issues to be aware of though. It’s called VB-Cable Virtual Audio and you can find the download page by clicking here. So let’s turn to a program that’s free, works on Macs and PCs and installs safely with just a few clicks. Soundflower has been the gold standard for years, but it’s Mac only and if you try to install it these days you have to override Mac’s newest security guidelines just to trick it into installing. There’s even one that’s actually called ' Loopback' but it costs quite a bit of money, so let’s ignore that one. That’s where installing a third party loopback application comes in handy. Streamyard also has a solution but it only works with Chrome tabs, so if you need to share sound from another program (like say Premiere for a tutorial!) you’re out of luck. Zoom has their own proprietary solution to this that auto-installs at the time that you install Zoom, but its actual quality isn’t fantastic. So let’s break it down.įirst, why would you need this? Well, anytime you’re screensharing content over services like Zoom or Streamyard that includes audio, you’ll need loopback sound of some kind. It can wind up being a kind of tricky concept, but it has myriad uses, especially in the days of social distancing.

This is the concept of virtualy routing the audio out from your computer directly to a destination without needing any cables or additional hardware.
