Hello,

I have some strange cracking noise during playback  , like wordclock sync noise  with my RME Madi Card linked to my SPL Madison (optical)

Issue is the same if I play 1 or 16 tracks

The RME Card is the clock master , I've tryed to sync on madi & with a bnc cable -> same issue.

When I look to the Hammerfall Setting , clock is stable & link is ok , I tried 44,1K to  98K  -> same issue

I get those noise a lot with Reaper  but very few with Logic Pro.

I've tried different buffer size with no changing , CPU Load & Disk drive are below 4%

Here's my config :

Macbookpro(2011)  13.3 I5 sandy-bridge - 8Gb ram 1333 - 128 gb SSD Samsung
Sonnet EchoExpress II  thunderbolt to pcie Chassis
RME HDPSe Madi
SPL Madison 1260

Thanks a lot for you help,

Fab
