Yes, I have tried that as well. I also updated the firmware to the latest version as described here. Neither has helped.
I’ve noticed that when I install the v2.24 driver from here the tone board shows up as “XMOS XS1-U8 MFA” instead of “XMOS XS1-U8 DJ” like in the screen shots from the manual. Could that be an indication as to what is going on here?
