Windows 10

Win10 support FLAC, ALAC and MKV.
A welcome addition.


UAC2 (USB Audio Class 2) is not supported. This means that if you want to play high-res over the USB (anything > 24 bit/96 kHz) you need a third party driver.
I do think it totally incomprehensible that MS don’t support this 2009 USB standard.
OSX and Linux do so from 2010 on and Android is on its way.

 

If you are using a third party driver; check if it supports Win 10 before you upgrade.

 

According to PCAudioLabs latency has improved.

In Windows 7, the lowest latency numbers achieved were at a buffer size of 220 samples for a latency of 5ms.

In Windows 8, the lowest latency numbers achieved were at a buffer size of 179 samples for a latency of 4ms.

In Windows 10, the lowest latency numbers were at a buffer of 132 samples for a latency of 3ms.

According to SonciState:

Audio Core Optimisation - it will now be possible to define and isolate all the core audio processing to a single core, meaning no other processes will be able to interrupt the stream.
