OK, to reproduce the bug we need some pieces of information:
– What music file are you streaming? Do the following example files produce the same bug: http://www.eclassical.com/pages/24-bit-faq.html check the bottom “Test files” for flac files.
– Where do you stream too / what are the receivers? E.g. just one instance of Kodi version 16.1. Try to see if streaming to just one device reproduces the bug since it is easier to debug.
– What are your settings in SWYH: stream as MP3 or PCM. Capture rate and bitrate.
– Do you use HTTP Live Streaming or the regular mode?
