Clear the sound input buffer(s) before reading new sound.  This resolves some problems with sound skips at the end of songs if running without a gap set.

Also, if there are any unknown problems that leaves part of the input

than garbled sound which is much more subtle) on affected systems.  If
you think this might affect you, run mserv with '-d'.
