Thomas… Thanks for the info. I actually sorted things out I found that with all 3 of my Pi4 that they are all very sensitive to the DAC (Denafrips Pontus II and Luxman DAC-06) and different USB Cables. I tested each usb connector separately on each Pi4 with Ropieee and with my 2 Final Touch Audio USB Cables and was able to find a stable connection with one of the four USB connectors on each of my Pi4. I have been listening for several days with out a connection drop. I have no explanation to why this is the case.
My generic cable have no issues with either DAC or Pi4 but definitely does not sound as refine as my other USB cables. And as i mentioned earlier in the post I have no issues what so ever if I run my DACS off a Mac Mini or an Intel NUC with any USB cable I tried. In the end it all sorted out but it took quite a bit of testing and AB-ing to figure it all out.
Again thanks for your reply!
