no usb audio out since update android L



Hi all,
Since i updated my Note 10.1 tablet ( ed.2014 ) to android L, my external dac stopped working.
The usb dac is the Dragonfly 1.2 (Audioquest) and worked fine before, plug & play.
I tested the dac, the usb-otg cable and also the usb connection of the tablet => they are OK.
Hardware hasn't changed, so to me, it looks like a software problem.
Is the usb power output (more) limited ?
I used the "usb host diagnostics" app that tells me the dac is still recognised.
Is there a way to make the dac function again, or do i have to go back to the earlier version of android ?

thanks !

Jo
