Recorded files: Call back may not occur if reset_limit is too long

[rct]

When using '-r' to play back record files, the call back function will not get called if the reset_limit is higher than the number of quiet samples at the end of the test file.

In my case, I had set a high reset_limit (20,000 samples), but the recorded file had approximately 10,000 quiet samples after the signal at the end.

I suggest that during development with recorded files, set the reset_limit below 10,000.

This might still be an issue, I'll need to check this.

ok, this is already solved as we always add an empty buffer last when using file input
