Audirvana won't play after a good night's sleep

Origin
1

I have recently switched from Audirvana 3.5 running on a 2012 Mac Mini (fronted by a browser based remote control system I created) to a new Mac Mini M2, Audirvana Origin (trial), and Audirvana remote (on Android). All seemed good with that new setup. However, when I switch off Audirvana and put the Mac Mini into sleep for the night, I can’t get Audirvana to start playing again the next day. I can perform any action in Audirvana (load albums/genres/artists, select albums to play, move from one song in the album to the next and back again, but the only function I can’t perform is “play”. It doesn’t respond from the Audirvana remote, nor if I go into the Mac Mini directly and click on the play button from there. The only way to get it to play is to stop Audirvana and re-start it - then it all works again.

This kills the idea of using my Mac Mini & Audirvana as a headless music player. Before I give up on this system I wanted to ask if anybody knows what problem I might be facing, or how I can go about debugging it?

Speaking of debugging:

Hello @wak

My go-to is, after many years with computers…

a. Turn everything off
b. Wait for a minute or two
c. Turn everything on.

If that fails…

a, and b plus… unplug everything and wait 30 minutes, then plug back in and then… c.

Report back

Regards

Phil

Sounds like a wake from sleep issue with macOS and/or your M2 Tech Young DSD DAC. I notice from the Young DSD manual the following…

“To comply with UE requirements regarding energy saving, the YOUNG DSD is able to
automatically switch off after a certain idle time. By idle we mean a time lapse in
which user didn’t access any control, like volume or mute”

My KEF speakers also have a sleep timer and sometimes when attempting to play, Audirvana times out before the KEF’s have fully powered back up causing Audirvana not to play and requiring a reboot of the software to restore normal operation. (The play bar controls grey out)

When you wake the mac from sleep do you cycle the DAC on with the Young DSD remote before initiating playback via Audirvana? I do this if my KEF’s have gone into sleep mode for 5 seconds or so before initiating playback through Audirvana, this resolves the issue for me.

That’s a good callout about the DAC. Given that the PLAY button is only function that doesn’t work when this happens it’s very plausible.

The timeout on the DAC is set to 0, which disables the timeout function.

I do use a remote (Logitech Harmony) to wake up the system, and the DAC came after the Mac Mini. I switched this around but that didn’t make a difference. But since this is more logical I will keep the new sequence anyway.

When things were stuck again after some period of inactivity, I noticed an Audirvana message “Exclusive audio access mode disabled”, which surprised me because I did have that enabled. After further digging it turned out the Sys Optimizer, which I also had enabled, was missing a helper app and also full disk access permission. Since fixing these two issues the problem has so far not reoccurred. Keeping my fingers crossed.

Thanks for your help and taking the time to look into this. I very much appreciate it!
