Bug Description
With my bluetooth headset (A2DP audio protocole) when I watch videos streaming with Google Chrome for example. there is a delay increasing between audio and video. I tried to change and set up the audio latency, but the delay increase, as much as I play bigger video
ubuntu 17.04 or 17.10 64bit
If the delay increases over time then mathematically it sounds like the output is consuming bits slower than the input. So /maybe/ you have 48kHz audio being played at 44.1kHz but I would have thought that would be noticeable (sounding distorted - too low). And even if that's not the problem, the delay should hit a limit via some buffering limit, after which it turns into skipping (bug 405294).
Another thought is to see the suggestion in bug 1677202.
