I am using my PC and JRiver to listen to Amazon Music Unlimited over HDMI to an Anthem AVM70. I am currently using the DSP function to encode the datastream (using WDM driver) from Amazon Music to Dolby Digital (AC3) and send that to my AVM70. This works perfectly, except it is limited to 48Khz sampling rate. The Audio Path shows JRiver is downsampling the incoming 192khz rate to 48khz. Dolby D+ supports much higher data rates. Is it possible to encode the incoming stream to Dolby D+? The AVM70 does support DD+ and 192khz sampling.
