Re. audio: we have made a lot of improvements in the last update and will do so in the next. A big limitation of AMLogic in the past was that you could only output 2.0 or 7.1 channels as LPCM on S905/905x/912. We are now able to output audio in its native container format with channel masking so that AVRs can perform post-processing when necessary (i.e. 5.1 upmixing to 7.1.). While most users use passthrough; there are some formats like 3.0 which will benefit greatly from this scheme. 

This is particularly useful for Freeview HD 5.1 (*) AAC content in the UK, as well as other AAC multichannel, FLAC and PCM multichannel content, or for True HD/DTS HD MA output to PCM-only AVRs (some early HDMI AVRs only supported PCM and didn't support True HD/DTS HD MA)

(*) And other audio formats.  The BBC has certainly broadcast 4.0 in the past (Wimbledon was originally 4.0 not 5.1)
