I really want to use the PIX recorder for monitoring and recording the program output, but it seems to be the device causing the bad audio when it's connected. Let me know if there's any more info about the setup. (2) Epiphan AV.io SDI to USB 3.0 interfaces I mainly use the dock for the hardwired RJ-45 connection.Īpple MBP Retina mid-2015, OSX 10.12.1 Radeon R9 M370x, 16GB RAM, 500GB SSD I've connected the USB 3.0 converters on the dock, and directly to the MBP with the same results. I've tried several HDMI cables with the same result. However, the sound totally clears up when I disconnect the HDMI going to the PIX-E7. I hear this when I monitor the headphone out of the PIX-E7, or if I which the audio out of the Mac to the headphone out. Sometimes it's fine, but it seems to be stressed when I switch video sources, add/remove lower 3rd titles - meanwhile I hear the ping-pong audio and distorted sound. Unless I have the MBP set for HDMI audio out, and sending audio out in the preferences of WC, I won't hear the audio. I open WC, and select "External Display Output", then choose the PIX-E7, the program out video of WC shows up on the monitor.

With I connect the HDMI out of the MBP to the PIX-E7, I get the wallpaper and system sound of the MBP - this is even before I have WC open.

On the MBP, under System Preferences, Sound, Output, I'm set for HDMI. In WC, in preferences, general, audio interface, I'm set for HDMI.

I've gone through the audio setting on the macs and WC. It doesn't sounds this way all time time, it comes and goes. The audio sounds like there's a ping pong delay and also distorted or "bit crushed". I'm running two MacBook Pros (will list full specs below) taking the HDMI out into a Video Devices PIX-E7 monitor/recorder. I have a problem happening with two WC Pro machines running the same project file and similar hardware.
