Reuse output buffer for directaudio, instead of reallocating each iteration

I'm confused why this change is needed in the first place. The output buffer is allocated only once already - when the output thread starts, it becomes "stuck" in an infinite loop inside run_send_loop until the output device is running. So there's no multiple memory allocations. I might miss something of course.

Could you please share your motivation of why these changes are needed?

Looks like your old code is ok, I don't currently see why it should be changed like this. In the changed code DataSender has to carry around a Box, which makes it less flexible even.

Ah, my honest mistake. I thought run_send_loop is called on each iteration.
