I've never tested this, but I designed the jitter buffer to work from
two threads even without using a mutex. This would work as long as there
is

Then it would be a problem with the packet loss concealment. It's
actually decreasing the level of the interpolated audio with time. Maybe
it's n...

Actually, I oversimplified a bit. I check if valid_bits has been zero for
the last 4 frames or more, because once you interpolate more than 100ms
from the last known state, you end up with some weird
blipp-blopp-blooiiing sound. Actually it reminds me of the ambient sound
of weird aliens in bad 50s scifi movies. At that point, silence is much
better :)
