Status - DTS SD Decoder working under GStreamer on Efika MX and I have Dolby PrologicIIx working but not under GStreamer yet. Dolby Digital SD decoder runs under Linux GStreamer in 2 channel mode and I will get the 5.1/7.1 decoder running later this fall.

I plan to build a bass manager , bit stream detection and Gain/delay manager as I get further into this project and as time permits.

Another task is to have streaming audio in via USB from external source supporting isochronous audio playback.

Looking into USB driver support on this as a separate project tbd.
