Subject: [PATCH] wavparse: convert all non GST_FORMAT_BYTES to format bytes.

Convert all non GST_FORMAT_BYTES to format bytes:
fixes:
GStreamer-CRITICAL **: gst_query_set_duration: assertion `format ==
g_value_get_enum (gst_structure_id_get_value (s, GST_QUARK (FORMAT)))'
failed
when playing more than one wav stream.
