Support for Dolby Digital? I have an embedded Android system and I connect it to my TV via HDMI.

Also my system has an Optical audio port.

I would like to know...

Does Android support Dolby digital (via MHL or HDMI or any other option)?
Though I found no concrete specs saying all (or which) Android devices might (or might not) support it, there are strong indications that it's possible (and at least partly supported):


Jabra advertizes its app for Dolby sound. No explicit mention of "Dolby digital, though.
XDA has a thread titled Beats audio with dolby digital advanced audio; as you can see, this explicitly mentions "Dolby digital". As this discusses an Android app, this pre-supposes the technical possibility.
AndroidAyuda.com has a Spanish article on this topic, which also implicates the availability


There are about 5 million hits for a google search on 'android "dolby digital"', which you might want to check some more from. The few I've picked didn't state any restrictions as to the device (though there are probably some, for what use does the support make if you have no appropriate output, such as HDMI). But it's clear that the Android OS is no hindrance to it.

TL;DR: Android itself can obviously deal with it, if the device supports it.
