New firestick 4K max gen 2 dts no audio

Ok so PCM would be the expected format as DTS passthrough is not actually supported by the device even though it stated it does. The reason there was no audio to begin with was because we enabled DTS passthrough support when we were told it was supported as we had no devices to confirm with as it was before the devices were officially released. After users reported no audio we disabled HW support for DTS so it is now using SW decoding to play DTS which will result in PCM.
