Is there any technical reason why it is not possible to pactl set-sink-formats X "pcm dts-iec61937 ac3-iec61937" when the Digital Surround 5.1 IEC958/AC3 Output profile is selected?
It would be convenient to not have to switch profiles when watching a movie with audio that is already encoded AC3.
I noticed the dcaenc plug-in for DTS encoding does the same thing. So maybe there is a good reason for this I'm not seeing.
