Firmware updates to improve streaming with UPnP and Qobuz Connect - blair.athol - 25-Nov-2025
As many of us, I am looking forward to further improved streaming capabilities and for the once promised infinite upgrades for my Expert 220 Pro CI.
Recently I tried to connect via UPnP with MConnect on my iPhone to stream from Qobuz in high quality since Qobuz Connect is not available.
Although I could connect the Expert via UPnP, I was astonished to receive an error message "The device has send a fault response" when I tried to stream a song from Qobuz.
So, I contacted the Devialet User support asking for help.
Indeed, Giorgos answered very quickly and provided some hints to determine the cause of the rejection.
This included System Power Cycle, to uplug and plug-in the Expert, to restart the router, a test of the stream resolution (Hires, vs, CD vs. MP3/AAC) and my firmware version.
I did send my results to Giorgos, indicating that I do run the latest firmware 13.2.0 with DOS 2.2.6 and that streaming was possible with AAC but not in Hires nor in CD quality.
This is what Giorgos kindly replied:
Thank you very much for your comprehensive reply and for meticulously testing the streaming resolutions.
Your feedback, including the fact that standard CD quality (44.1 kHz) fails while AAC streaming works, is highly valuable.
Based on this detailed testing, we can confirm that the issue is not related to your network configuration or a simple software glitch that can be solved with a power cycle.
Instead, the persistent failure to play standard CD quality streams points to a specific protocol incompatibility or a bug within the Devialet Expert's current UPnP processing firmware (SW 13.2.0) when communicating with MConnect for Qobuz streams.
As this cannot be resolved through troubleshooting steps, I will immediately escalate your detailed report and the specific error response to our Engineering and Development Team for deeper analysis.
Your issue with the current UPnP path will be taken into consideration for a future stability patch.
Furthermore, your suggestion regarding the introduction of native Qobuz Connect is highly appreciated and will also be forwarded to our product development roadmap for consideration.
Thank you again for your patience and for helping us identify this specific limitation. Please register to our newsletter, when an update regarding this issue is released.
Best regards,
Giorgos | Customer service & support Devialet
Now I am looking forward to further updates, Hope springs eternal
