Good afternoon all, I am running 10.0.144 on a 2014 Mac Mini with 500G standard HD, 2.5 I5 and 16G of memory with Mavericks 10.9.4. No other applications are running as this is primarily a music server. It has not been stripped down, the OS is in standard config. Blue Tooth and WiFi are off. All media is on a WD 4T Thunderbolt external drive running RAID 0 (disk clone so there is 2G available). The output is sent to a Sonore Rendu (also 2014) with no software up sampling. JRiver has been working fine for the past several months but recently I have noticed that it is playing only partial tracks before going to the next (which it will play completely) or skipping tracks all together. Initially I thought it was a bad file but when JRiver was unloaded and iTunes loaded, all tracks played without incident. I have roughly 17K tracks or 1.2T most either AIFF or MP3 320, very few FLAC, m4a or other files. Most tracks that are misbehaving are aiff but this is an observation not a tested theory.
Things tried to date:
Reboot
Repair disk permissions and reboot
Ensure that all file access on the local HD and the WD are correct
Delete and rebuild the JRiver library
Turn on and off the "play from memory" option
All this to no avail in fact it appears to be getting worse. I do not play with the configuration much as the systems plays music all day in my home office 24x7
Suggestions would be greatly appreciated.
