Hi Abby,
As far as I know, we don't have Android driver for TAS5760L. Users have to develop the driver by themselves. Please try to generate the configuration by PPC GUI and send write the driver with it.
Fortunately we have Linux for another device TAS5782M. Please find it in below, hope it helps you.
