Audio comes through on my Xbox One and PS4 just fine. However, on my PC if any audio begins (like in a video or video game) the sound takes a little over a second to begin coming through. Do you know what could be the issue? There is no synching issue, it just is silent for a second before it begins. I am using high quality HDMI cables, all of the same type and brand, and running each device into the sound bar.
Try right-clicking the audio icon in your notification tray, and then clicking "Playback Devices." Your sound bar should appear in that list somewhere. Right-click it, and then click "Configure Speakers." See if adjusting those options helps. Also, if you have any Bluetooth devices connected to your computer try disconnecting all of those to see if that helps.
