How to manually install Stream Only Audio option when it’s not available
There are certain cases wherein the Stream Only Audio option on XSplit Broadcaster will be grayed out saying Stream Only (Install) That looks something like this:
In these cases, we can manually install the feature to Broadcaster through the following steps
Make sure XSplit Broadcaster is closed and is no longer running on your PC.
Open File Explorer, then go to C:\Program Files (x86)\SplitmediaLabs\XSplit Broadcaster\x64. Look for instvad32.exe and instvad64.exe
Note: instvad32.exe is for 32-bit OS, while instvad64.exe is for 64-bit OS only. When installing it on a 64-bit OS use both.
Right-click on instvad32.exe, then select Run as administrator. Repeat this step for instvad64.exe as well.
Open XSplit Broadcaster and the Stream Only audio function should be working but there are some instances that it would still show Stream Only (Install), if this happens select it and it should automatically install.
If the issue persists, contact XSplit Support they are available 24/7.
