Roon 2.0 Build 1164 and ARC Build 90 is Live!

Hello Everyone,

Testing has revealed several cases in which Android devices are downsampling to 16 bit when playing to an attached USB DAC and the primary purpose of this build is to address that issue. If you previously experienced this problem, or other issues related to playback to a USB DAC connected to an Android device please give this build a try and let us know how it goes.

There are a few other minor fixes included and those are detailed below.

Thank you for your continued support,
The Team at Roon Labs
