Hi I have a strange behaviour here: After a minute or so playing audio to my Topping E50 Audio-DAC it switches off (goes into suspend). According to the world wide web this happens if the DAC does not receieve a valid signal. Which is strange for many reasons, two of them are:
This happens while music is playing
This behaviour is new, it used to work flawlessly since I use this setup.
My System: Old Macbook Pro (from 2012 or so), Audirvana Studio latest version, Topping E50 DAC
This happens when I playback from harddisk (external SSD) and streaming from Tidal. It the same wheter I start directly from the macbook or start remotely with iphone or ipad. I’m on the studio subscription.
Hi @Audiopilot could you confirm how you DAC is connected to your Mac and also run your debug info from your Settings/Account page and paste the information in your reply in this thread. Hopefully someone can ascertain from that information what the problem could be.
I would also turn everything off in order of speakers/dac/Mac/router and remove plugs from power sockets for more than a minute, then restart in same order just to see if that irons out any kinks in the setup of the system.
Good luck…
If you can play your Local Library files using the built-in speakers as expected… then you have a point of reference from which to trouble-shoot your system… If you can playback from the built-in speakers, you will need to suspect the DAC or a bad USB cable or adapter… Verify the USB port the DAC is connected to if functioning by attaching something else to that port…
You can also verify the USB devices operating on the USB bus by opening “About This Mac” and opening “System Report” and look in the “Hardware” report for “USB” and select to open the USB bus report to see the devices operating on the bus.
Here you are, but I don’t see something suspicious:

This is suspicious:
You are allocating 13.3GB of your 16GB System RAM for the playback pre-load memory buffer… I suggest lowering this allocation to @ 4GB.
You are leaving approximately 3GB of System RAM for macOS… You don’t need more than 4Gb for playback pre-load buffer… Increasing the available RAM for the OS, reduces virtual memory disc-swap request interrupts and the OS operates more efficiently…
This is your interpretation of what “other tasks performed by your computer outside of the application” applies to…
You forget about bus management, system buffering, etc, etc… Audirvana does not run without CPU cycles and bus management sub-routines, etc, etc, like Core Audio functions and transmission protocol CODECs and the control of the flow of the memory bus architecture(s). … You are making a presumption regarding the default allocation of System RAM…
