Got my Chromecast a few days ago and just discovered I get higher resolution audio from my tablet than my laptop. Here is the scenario: I connected my Chromecast to my Blu-Ray player's HDMI input (I have an Oppo BDP-105 Blu-Ray player which has various types of digital inputs). When I play music from my laptop, I use Google Music in the Chrome browser. I transmit that to my Chromecast and my Oppo states the music stream is at LPCM 2.0 32K. But when I open the Google Music app on my tablet (Nexus 7) and transmit the same song to my Chromecast, my Oppo tells me the streaming music is LPCM 2.0 44.1K. Any reason why I get higher resolution audio from my tablet than my laptop???
