Audio Mixer Troubleshooting
If using a third-party audio mixer in conjunction with Production Truck and encountering issues please see the recommendations below. In this particular document, the Behringer Xenyx Q1202USB is used. While it cannot account for every audio mixer available on the market, there are likely similar settings on your mixer.
"Failed to Start Audio Capture Session" Error on MacOS
For more information on this error,see: Mac OS Camera & Microphone Privacy Setting Issue. If you see the "failed to Start Audio Capture Session" error or if Production Truck is not seeing your audio mixer at all, this is a good first step.
Navigate to the Mac's System Preferences>Security & Privacy>Privacy tab and enable Production Truck under the Microphone setting.
Verifying the Audio Mixer is being Detected by the Computer
If the audio mixer is not coming up as an available source within Production Truck, ensure that the computer is registering the audio mixer as a device.
With the mixer plugged in, navigate to your computer's System Preferences then Sound or Audio.
This setting may be in a different location depending on your computer's operating system.
Under the Input, tab ensure that the audio mixer appears. It may not appear labeled as the name of the audio mixer, but instead as Line In or USB Audio Codec. Test that the mixer gets audio levels by looking at the Input Levels fluctuating in the Sound settings.
If you do not see your audio mixer appear in this section, Production Truck will not be able to detect is either, as the computer as a whole is not identifying it.
Verify the Audio Mixer is Connected via USB
In order to ensure the best audio quality and connection, it is recommended to bring in Audio Mixers over USB. It is not recommended to bring them through Audio Jack. Most mixers will have a USB option.
The previous solution also ensures that the computer is detecting the mixer and there is likely not an issue with the USB cabling.
Checking Phantom Power and Main Mix settings
Two buttons that are specific to bringing in a mixer over USB are the Phantom Power and Main Mix buttons.
If mixer has a Phantom Power button, it should be enabled.
If mixer has a Main Mix button, it should be disabled.
If mixer has a 2-TR/USB to Main button, it should be disabled.
Please note that these are specific to this mixer brand, we would recommend consulting your specific mixer's recommendations for best use.
While these do not directly affect Production Truck, they do affect the mixer's ability to send to a computer.
