Berkeley CA audiophile is desperate need of help

I have an Innuous Zenith 3 and PS Audio Directstream dac.  Occasionally, they stop speaking to each other or stop making music for some  reason .  I begin by powering off the Innuous, waiting a few minutes and powering it back on, as has been suggested.  If that doesn't restore the music, I do the same with my dac. I check all cable connections.  I've found that one of my usb cables  isn't very tight and can come lose.  I check the inputs on my preamp and dac to make sure they're set properly.  Sometimes the problem is just a stupid mistake like forgetting to turn on my power amp.  My Innuous is connected to an Orbi wifi mesh router. If the other steps haven't worked, I power cycle that.  If all else fails, I contact Nuno at Innuous (support@innuous.freshdesk.com).  He's very helpful.  I hate it when my system is down but so far, by trying each of these things in order, I've been able to resolve the problem. Good luck.

@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).
