you're welcome!
there are few things, like check the "use root" checkbox in tasker, and really try to commands first in adb shell, to make sure they work (as root)...
for me it works just fine. although it would be better not to have to use such "workarounds"
Yeah, I know what you mean about the workarounds. Ever since Magnum Opus though, all I have to do is open V4a. No exiting 1st. And Dolby hasn't given me a problem so far so I don't have to worry about that now.
