Berkeley CA audiophile is desperate need of help

@Brownsf, I've done everything you've listed. I've 

used different USB cables and checked each and every thing. 

I've had remote support with Nuno as well. I thank you for your response!

Tomorrow I will start again by reconnecting and 

powering everything up, as if for the first time.

Thank you again.

@bander Hi, I’d first check your DAC is working by plugging a computer into it. I understand you’re using the USB input of the DAC.

If that works you’ve probably got a "handshake" problem with the server. Do a factory reset if possible and then connect to the DAC before you start the DAC up.

Also ensure your server updates are current.

@bander, Please also reboot your modem and router. These means power off for 2 minutes and then restart (remove batteries, if any in these devices).

If there are any software updates for your router, you should apply these updates.  

You might find it valuable to join your local audio lover's group, the San Francisco Audiophile Society.  I preferred the original name (Bay Area...) and the group's membership is even broader than that.  They have a forum where you could make this request, and hopefully find some local help.  More than that, there are meetings & guest presentations (Zoom for now), even the occasional sysHop to hear others' systems (alas, also rare in these times).

Digital is extremely sensitive to dirty electricity which will cause dropping the server, dac or both requiring powering off and on again. Is your digital on a good conditioner or being feed clean power.

I had these problems described above until I cleaned up my power , now no more.

just saying check your power
