Buffering for a few seconds, then nothing, never plays

was working perfectly until this most recent update. now it buffers to my oppo 205 for a few seconds, then nothing. if i switch to internal device playback, it works fine. i have rebooted both my macbook pro and my oppo several times and still no love.

is there a way to switch back to the previous version that worked?

after jumping through some fiirey hoops, i cured the problem. if anyone has this issue, contact me and i can walk you through it.
