I'm trying to watch a movie with my wife, and we are both using headphones — she is using Bluetooth, and mine are plugged into standard 3.5mm headphone jack.
I've created "multi-output device" in Audio MIDI Setup, added both headphones to the list of devices, so this setup outputs sound to both devices at once. Problem is that there is noise.
Whatever output is set as "Master device", it does not suffer from noise, but the other has frequent loud clicks (just like if audio frame is being ripped). Playing with sampling rates and drift correction didn't seem to fix this. I'm using OS X 10.9, and I've tried this on three different Macs, so it's definitely not a hardware issue.
So, is there any way to get rid of those clicks? Some lag is generally acceptable, as long as those annoying clicking noises are gone.
