We had some feedback of connection issues of Devialet device using DOS2 with Audirvana. Regarding this issue Devialet support team shared a workaround for it and a member of the forum shared it in a previous post (thank you @Pwalder).
For any others experiencing the same issue of Audirvana not ‘seeing’ their Phantom(s) the solution was:
Obtain the IP address for each phantom you have. e.g. 192.168.0.14
Enter the IP address into Safari and this will bring up a Devialet Phantom configurator web page
On the configurator page locate the Wi-Fi tab. Check that it already has the correct Wi-Fi network name and then enter the Wi-Fi password into the relevant dialogue box.
Click SUBMIT,you should see ‘Success’ feedback.
On quitting the Safari page you are offered the opportunity to save the password.
Repeat the stages 1-6 for both Phantoms if, like me, you have a stereo pair
If you then go into Aurdivana and bring up the Devices Dialog box you should find that a new option has become available in the Network section. In my case it was the name of my Phantom stereo pair. Selecting this then made the Phantom pair available and for me solved the initial issue.
