Further adjustments to the silence thread -- make the sleep time 30 ms, thus if the queue goes below 60 ms of samples, silence will be inserted unless an audio write occurred within the last 30 ms.

Don't send silence into the alsa device within the scanner's sleep time of the last legitimate write to it. This is to stop the scanner inserting silent frames while the player is flushing fames.
