[Bug 1738907] Re: Bluetooth audio latency / delay increasing on video streamig

[Daniel van Vugt]

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.
