This means it was recently streaming hi-res and now it is not. Have there been any changes made to your system in the last few months? Are all your settings in ALL devices set correctly? Have there been any software or firmware upgrades that might have reset some settings? Please double check your DAC and ensure all cables are okay and so are settings.
I believe you said the h-res steaming was an issue for BOTH Qobuz and Primephonic. This probably means these streaming services are okay and the issue is your configuration, etc. As I posted above, please also update the firmware in your router and Extender, if you have one.
If you continue to have these hi-res steaming issues, please list you hardware and software. I am running out of suggestions and am hoping someone else can find the issue.
BTW, it might be something ’obvious’, so please review everything again (sorry). For example, could it be a hand-shaking issue between your streamer and DAC. Please reboot these devices in a different order than before (maybe DAC first and then the streamer, etc.).
