SAW hangs in Live mode after sample rate change

[Dave McKenna]

Hello fellow SAWyers...

Recently upgraded my Windows 10 SAW system with a new Ferrofish Pulse 16MX converter and RME MADIface Pro interface. Compared to my previous setup, this new one allows me to change sample rates any where from 32kHz to 192kHz, so probably why I'm only seeing this problem now (never changed rates with the old setup). Here is an example of what is happening:

1. Set MADIface as clock source, set to 96kHz
2. Open SAW, set sample rate to 96kHz (24 bits too)
3. On track 1, choose a device from the MADIface as the input source
4. Hit the 'L' key and now we are in live mode and get a signal so it works - hit 'L' again and it turns off live mode. Easy to toggle back and forth.
5. Change the sample rate in SAW to 48kHz
6. Hit the 'L' key to enter live mode - the MADIface ASIO widget shows that the clock has changed to 48kHz

At this point, there is no sound coming thru and if I hit the 'L' key again, nothing happens. It seems stuck, although I can navigate the interface and change settings in SAW, but none of it has any effect. I have to right click the SAW icon on the toolbar and choose 'close window' to get out. This happens in both SAW32 and SAW64. Have also had trouble when loading EDL's with different sample rates (something that happens a lot these days with the new rig), but that usually sorts itself out after a 'shutting down engine' type message.

Maybe this is specific to my setup, or maybe it is simply a 'Don't do that!' kind of thing. I was wondering if anyone else has seen this and if there is a remedy - maybe a setup problem? Thanks for any insights...
