Perhaps they would remove Dolby HD and DTS HD instead ... but that sounds most adventourous.
There is a flag on the HDMI configuration register than needs to be set to signal compressed audio vs. PCM. That register is reserved/disabled on the mobile tablet Baytrail. Probably because of limitation in the integrated Intel SST audio decoder. Check the datasheet. So you will never get AC/DTS from a tablet SoC and the format is not exposed in Windows audio device properties. The desktop Baytrail does not have this hardware issue - just lack of drivers for HD audio in Windows.
