Audirvāna Studio 2.1 and Devialet Phantom?

I am testing AS since last week. I have a couple of issues, but this is a new one. AS is running on a headless Mac mini streaming via UPnP to a Stereo Pair of Devialet Phantom. Music suddenly stopped playing. I checked with AS and it lost connection to the Phantoms playing to the internal speaker, no Phantoms available. Neither restarting AS, nor the Mac made the Phantoms appear. Tested the Phantoms with other wireless sources, everything works fine. The Phantoms are turned on every day via electrical switch. The Mac mini is sent to sleep overnight. Is this related to the 2.1 update or is it a Devialet issue (Firmware 2.16.1)? Following please find the debug info. After rebooting the Devialets, the connection could be restablished.

Try moving your audio buffer up to 4000mb, power down your speakers (unplug), fully power down your network modem, router, switch, etc. Restart your system and give it a try.
Best luck with it.

It is working now again. I am testing Roon as well, because I have to decide which subscription to keep. I have to admit that Roon is sleeker, more convenient and robust (not a single issue in 3 weeks). Nevertheless, their upcoming price increase is something to consider. Right now Audirvāna creates more issues for me, but my hope is that AS will improve over time.

Very good, I’m in exactly the same boat as you. I’ve just taken a one year roon sub, it’s working so seamlessly with several different pieces of kit that I have. I’m finding that the sound quality is very equal it did take me some learning curve to dial the dsp stuff in on roon vs my plugin stuff with Audirvāna. It’s more about UI at this point in my opinion.
The thing that I was trying to see with your phantom system is if it’s like the issues that kef active speakers have, some kind of handshake issue that requires a full power cycling. You turn the speakers off at speaker or at wall socket?

I turn them off at wall socket every night. I know this might not be the best option, but one of them is a first Gen which consumes quite some power when idle. The other one can be sent to sleep via back button. I did not need to full cycle all devices today, just the Phantoms to make them reappear. From next year on Roon will be about double the price (12.49/14.49) vs. Audirvana … Still undecided what to do.

There are the same complaints about KEF’s and Devialet’s on the Roon forum too. The answer on the Roon forum is also always:

  • Do the basics first meaning: power off/unplug and restart everything.

This has more to do with wireless protocols and KEF and Devialet than with Roon or Audirvana I am afraid.

I am aware of the challenges of streaming audio and wireless network setups. Over the years I navigated those in different setups. In my case it is simply the small things that add up to a point where, at the current stage, Audirvāna is less reliable for me and more tedious to work with. So far (3 weeks) Roon has never failed me and is definitely more robust in a server setup. Audirvāna has been my main software for a couple of years. Nevertheless, I would like to give Audirvāna Studio a chance as I hope it is a more modern and robust framework. I am not talking about local DAC output, where I think Audirvāna is superior. But for wireless Roon seems to have the upper hand.

Have you tried setting a fixed IP address?

Yes. Server has a fixed IP :slight_smile:

Devialets I mean.

Ah, OK. I will give it a try.
