Hello, with this DAC it plays too fast. What is the problem?
Any hints to change this?
It’s due to a sample-rate mismatch at your DAC…
Audirvana is the ‘master’-clock and your DAC must be set as the ‘slave’ to the external master-clock/sample-rate sent from Audirvana.
Please post your debug information here, found under the Audirvana menu pull-down window or ‘Debug Info’ button in the My Account section of the Settings window, so folks can see how you are configuring your system and help you better.

Sorry for late answer, unforeseen things hold me tight.
With Apple Music there is everything fine.
BlackHole could be causing the sample-rate mismatch… It’s competing with Audirvana for Core Audio services…
Also, you are allocating 13Gb of your system RAM (16GB) for pre-load playback memory… lower this to 6GB or lower… adjust for best performance.
Ok, thx for answering. I will remove blackhole and adjust memory according to your hint.
More tomorrow evening, I will tell, what happened.
Kind regards
It appears you have two Oppo 103’s connected… one via USB and the other via Ethernet? If not, and have one BDP-103 connected via both USB and Ethernet, make sure you are not sending signals to both inputs simultaneously (BlackHole?)…
It’s only connected via HDMI. Network should only be my home network, no upnp or similar.
Well… The report is showing it as a connected UPnP device also…
From pages 61 and 62 of the User Manual of the BDP-103:
http://download.oppodigital.com/BDP103/BDP-103_USER_MANUAL_English_v1.8.2.pdf
NOTE
If you use HDMI to connect audio to an HDMI A/V receiver or audio processor, it is important that you choose 720p or higher HDMI output resolution when playing high resolution audio content (DVD-Audio, SACD, Dolby TrueHD and DTS-HD Master Audio). According to the HDMI specification, the bandwidth available for audio is proportional to the total bandwidth used by
video. At 480p/576p resolution, the HDMI specification can only support 2 channels of audio with high sample rate (up to 192kHz), or 8 channels of audio with standard sample rate (up to 48kHz). If you play high resolution audio content at the 480p/576p resolution, you may get reduced audio resolution, incomplete audio channels, or even no audio/video output at all. Choosing a higher output resolution such as 720p or above allows enough bandwidth for all high sample rate audio channels.
This one from the manual is for the other direction- outgoing from Oppo.
The input is chosen via remote (HDMI) or app (upnp, dlam).
Okay… Does this also apply to HDMI input from an external master-clock sample-rate and Is the BDP-103 configured for 720P or 1080P?
At this point, it’s my feeling that both BlackHole and your Multi-Output Device configuration in Audio MIDI Setup is mis-configured with an incongruent Master Clock Source and is creating the problem or some mis-configuration of the BDP-103.
Blackhole is not on the Mac anymore. Wrong Speed stayed. 
Hi @Jens1,
Can you go in the audio midi setup app of MacOs and then try to lower the sample rate your HDMI output can use?
