Picoreplayer also playing everything at 48K via USB. I see that this is the ALSA default but I can't find what to put into the picore Alsa and/or upsampling settings to either play the file at its native resolution or to upsample everything to 192K. To further complicate issues, I got my digi+ board today and attached it via spfif coax.
I'm thinking about native support - a plugin for the lossless stream and the ability to use the other features like the android app "The (Android) app features our HD Slideshow of images synchronized to the music (particularly nice when viewed on a tablet), song lyrics, and the comments & opinions about the songs from your fellow RP listeners."
Installation: Bluetooth support can be installed on piCorePlayer via the [ Tweaks ] page on the piCorePlayer web interface. Please note: If you are planning to use both Bluetooth and WiFi, then you must connect WiFi through 5Ghz otherwise Bluetooth stumbles a little.
