Hi ,

I am using Omap4 Blaze board with Android Ice-cream sandwitch codebase where I have an usecase to play two different media audio at two different output ( for example one audio clip to HDMI and another to speaker/Head phone) . Is it supported by the underlying TI Hardware ?

If yes , then how should I check that ? Any testapplication can be ran to verify ? Any configurations need to be changed.

Please help !

Thanks
Danny

    Hi Danny,

    Yes, it is supported by TI, but having the audio in HDMI when plugged in is like the default configuration in mobiles, so if you want to break with that you have to modify the Android audio HAL that takes care of open the drivers, send the streams, etc.

    Happy hacking :)
