DSD512 with Aune S6 pro

Hi, is audirvana support dsd 512 on macOS? I have Aune S6 pro (DSD512), but in “Audio Settings” I can only see “Supported DSD rates”: DSD64, DSD128, DSD256. Why?


Mac doesn’t support DSD512, Audirvana yes… on a PC

Hello @sebulba,

macOS is not able to send raw DSD streams. That’s why the DSD over PCM standard has been developed: to send raw DSD in a fake PCM stream.
To identify it as such, there are 8 bit markers in it.
And the presence of these markers doubles the need of bandwidth, thus explaining why on a mac only half of the max DSD rate is available.


@Antoine, thank you for the detailed explanation :+1:
