the My Book looks like it is a backup solution. possibly there are settings that need to be turned on on My Book that allow it to be more than a backup, more of a NAS. i posit this as it seems like the objects on My Book are slow to stream, almost like a sub par network connection.
Problems with Audirvana connectivity
I have transferred 5 TB of hi-rez recordings to a WD My Book external HD which I play through my iMac using the 3.12.15 version of Audirvana. It always takes a long time for the selected music to start playing and often I have to click on the selected track several times to get it started. Then very often, the music just stops playing and I have to reselect it. When the music stops, I commonly get one or the other of these prompts:
"Stopping audio device" or
"Error: Unable to grab exclusive access"
Can anyone help me resolve this problem and get Audirvana to work correctly?
