Its always frustrating for us and the customer when they have issues with our gear.
We have thousands of BDP's out there now and have been trouble free for many of our customers for years. Generally the problems are network related but I understand the BDP tends to get blamed when these issues occur but I am sure Chris will be able to help after he has a look at what's going on in your specific setup.
My english is not the best, I try to explain better.
I have no problem with network, I never loose the network connection with BDP-3.
I can see it and find it on my Mac in "my.bryston.com", I can go in and configure it without issue.
It is connected to bda-3 with USB.
After playing for a while, from either ROON or USB stick, there is a sharp "hiss" from speaker(like when something is short circuit) and the USB "handshake" between BDP-3 and BDA-3 is lost.
The BDP-3 still plays files, but there is no sound.
It sometimes plays the files as normal, but sometime just skipping through all files in playlist.
Sometimes it is enough to restart the DAC, or restart BDP and DAC.
And sometimes I need to go into the menu and select USB and save.
Have tried 4 different USB cable and still the same.
Tried USB1 and USB2 on dac, and different USB out on BDP.
Not tried AES/EBU in ages, but have cable and can try to see if this is stable.
