Problem with DSD playback on Cocktail Audio X50

Core Machine (Operating system/System info/Roon build number)
iMac 1.4 GHz Intel Core i5 OS X Yosemite

Network Details (Including networking gear model/manufacturer and if on WiFi/Ethernet)

Audio Devices (Specify what device you’re using and its connection type - USB/HDMI/etc.)
1st setup > Cocktail Audio X50 > USB cable > T+A DAC 8 DSD (music files stored: Cocktail Audio X50).

2nd setup > Acer notebook ASIO 1.3 > USB cable > T+A DAC 8 DSD (music files stored: Cocktail Audio X50, no connection from Cocktail Audio X50 to the DAC, Cocktail Audio X50 just uses as the source of the files).

Description Of Issue
The problem: for the 1st setup, all DSD files will convert to PCM,

And no DSD option from the setup menu,

But when I use the 2nd setup, all DSD files play accordingly,


And the DSD option can be selected from the setup menu,

From the menu of Cocktail Audio, X50 can support DSD file up to DSD256.

I would like to know, with using the 1st device setup , how to play all DSD files without converting them to PCM (ie direct DSD like the 2nd setup). Anyone could help on this issue?

Thanks and regards,

Hello @Eddie_Wong,

Start by checking the DSD settings on the cocktail Audio X50. This can be found in the Settings > Audio > DSD Signal Type menu. For the T+A DAC 8 DSD, this should be set to DSD (DOP).


Dear John,

After changed the DSD output on Cocktail Audio X50 from “Native” to “DoP”, the problem has solved.
Thank you so much.
