Any one have a solution? I need a dual boot image android/linux that works spdif audio passthrough in android. Have anyone an image file or a solution to upgrade my software?

5

which audio format you test., dts/ac3?

6

Yes, dts ac3, dolby digital, and none of them work!

I check in settings → about the device->firmware->update and i have the latest firmware !

I try ugoos and rikomagic firmware and they work fine so the problem is firefly android firmware.

Any one have an idea or a solution for the problem?

Thanks
