If it's just play a particular genre in a random order, select that Genre on the Karma and then turn on shuffle.
Now I'm going to appear
really dumb!
The on-line help does not mention the word "shuffle" anywhere. The word "random" appears only in reference to the "Rio DJ" function.
So, ummm... after I select a genre on the Karma,
how do I turn on Shuffle?
I did look through the menus on the Karma, and didn't see it. Maybe I'm just not smart enough to own a Karma...
In my defense, the
only thing I use my own Karma for is listening to Audio Books, where shuffle mode would be counter-productive.
