A quick test and it turns ON/OFF ok.

Is it the only DSP options thats ON?

Actually I was able to reproduce an error condition with the Crossfeed and Polarity Inversion fields that may be causing your issue. The cause is due to bugs from an earlier refactoring of this code.

Run these commands to reset the fields to their default value then reboot.

Code:

moodeutl -q "update cfg_system set value='0' where param='invert_polarity'"
moodeutl -q "update cfg_system set value='Off' where param='crossfeed'"

This should allow you to turn off Polarity Inversion but it looks like the Crossfeed input is broken. A fix for that will be in upcoming 9.1.5.
