Default KaT Audio 1.5

Wondering if anyone has experience this issue with Kat Audio on the transformer.
I'm getting
"org.meerkats.kat.b.a: Exec error res=1"

In Timdurus thread there is some mention but all related to root issues. I don't have any root issues and even get this error running it as root in a terminal /system/bin/katmix 31

The error is write failed: EPIPE (Broken pipe)| write failed: EPIPE (Broken pipe)
