Rubix 22 highjacking audio on my PC

[Selsong]

HI I wonder if anyone else has had this problem and what they did about it?

I am using my Rubix 22 with Cubase 9.5 and it suddenly has started to hijack the audio and wont let any other device play audio on my PC. Normaly I can switch to another device to listen to something should I need to

Ive used "release driver when in the background" on Cubase but this makes no difference.

Even when I shut Cubase down it still seems to have a grip on the drivers and no other player will play.

I uninstalled Rubix 22 and re installed it and everything worked fine for a while, after a while it then just reverted back to the problem

Any help would be appreciated...... Its driving me crazy !!
Many thanks
