Topic: Sample rate changes with Thunderbolt connection

I have a Madi FX card in a sonnet chassis for thunderbolt, all fine, but as soon as I connect an additional thunderbolt device (in this case a harddisk) the sample rate of the Madi FX changes to 32000 Hz and the connection to the attached madi devicesis lost. Running a new mac pro, clock is set by the Madi FX card.

Anyone having this issue?

Thanks

Michael
