I have enjoyed using the Blackmagic ATEM Mini Pro video switcher, but have found it lacking in the audio output area. Users have widely panned Blackmagic Design for omitting a headphone audio jack in the ATEM Mini series. Any time that someone wants to live stream, they would want to check the outgoing audio quality. Blackmagic Design added the audio port to their newer ATEM Mini Extreme series after many reviewers requests.
I have been using the HDMI out port for MultiView, or Program View, to a Blackmagic Video Assist 7 inch monitor/recorder, or a Lilliput 7 inch monitor. Each of theses monitors has an audio port that allows me to plug in headphones, but I don’t always have these monitors in the workflow. Sometimes I use an HP 20 inch monitor, or a Samsung 28 inch monitor, and neither one has audio ports or speakers.
I just received this HDMI Audio Extractor below, that passes the HDMI through the unit, and has various audio output options. This solves the issue of not having an audio out jack from the ATEM Mini Pro, and allows me to monitor the sound quality. I also got it so that I could use the Optical SPDIF port with my Bose 5 Solo soundbar, and to put my Sony headphones in the AUX Stereo Out audio port. This saves me from constantly switching the audio out ports from my two computers that I use as input sources to the ATEM Mini Pro. I can always just route the audio out from the Macs to the BMD HDMI output, and hear the results on the Bose soundbar or the headphones.
I recommend this pass-through HDMI dongle for monitoring audio. I was previously having to route through a Blackmagic Video Assist or other device with a headphone jack to be able to hear the outgoing audio quality and volume.
