So when using Bluetooth on Linux and Android with random video players, they're all are surprisingly good at playing the video behind the audio to keep them appearing in sync with the Bluetooth latency. I wonder if Bluetooth has actual methods to measure the latency or if Bluetooth drivers just hardcode a "sensible delay" to try and keep it in sync

@kianga Oh yeah, it only works if it readily can "preroll" the audio, hence how mystifying it is to me that people want to play games with Bluetooth headphones since that's generated on-the-fly
