[FFmpeg-devel] libavcodec DTS decoder bug - LFE channel empty

With pleasure:


All 6 channels have valid (= visible in e.g. Audacity) data in them when 
decoding with Sonic's DTS decoder. But when decoding the sample with 
libav the LFE channel seems to be all silent in Audacity.

Regards, madshi.
