every now and then it happens if there is no data on the mic input port.
In this case it will generate a frame to keep in sync. In this case the
message is ok and harmless.
Especially for USB audio devices, even worse on a computers with poor
performance or some kind of processor speed stepping, I have seen the
same behaviour. On good systems even, it sometimes occurs after some
weeks of operation. In this case the PJSUA is always ahead of windows
and never seems to get a right audio packet.
I tried everything but I have no answer up to now. I upgraded portaudio
to the latest stable version and had some limited succes in opening and
closing all sound devices. The latter worked, but is very unhandy and
does not cover all circumstances.
Is there someone else experiencing this problem?
