Topic: FF400 wrong sample rate after wake from sleep

Hi there,
FF400 (driver 3.39) is set as clock master with 48kHz. To its ADAT there is a Yamaha console connected, that is synched to ADAT.  When waking my Mac (10.13.6) from sleep, the Yamaha console reads 44,1 kHz as sample rate, where as the FF400 is still set to 48 kHz.

Can someone shed some light on this behavior?

What does the console read during sleep? Perhaps it switches to 44 with no ADAT input and somehow doesn't notice the change afterwards...

It says "unlocked"

Anyone?
Is this a bug in the driver?

What happens if you toggle the rate to 44.1 and back to 48 in the Settings dialog of the FF400? Is the wrong setting also shown in the Audio MIDI Setup for the FF400?

That is what I have to do, to get a 48 kHz synch back, as the settings dialog still states 48 kHz right after waking the comp up. AMS reads 48 kHz as well after waking from sleep.

Confirmed. Happens because you either manually switch the FF400 off during standby-mode, or use it FW buspowered, so that happens automatically. After sleep with power off the driver does not set all parameters correctly. We will fix that in the next driver update.

Exactly, it is bus powered here.
Thanks a lot for your work! It is just so remarkable we still get support for a device which would be eol for others looooong ago.

Re: FF400 wrong sample rate after wake from sleep

Any news on that?

Re: FF400 wrong sample rate after wake from sleep

Is this still in the pipeline?
