PulseAudio Advanced Settings

In the 'pavucontrol' display, in "Output Devices," there's an advanced button. It has these settings(Asterisks mark the ones checked).

• PCM*
• DTS*
• AC3
• MPEG
• EAC3
• AAC

There's also latency, but let's not go there. Sound definitely decodes faster than video, but the fact that video decodes at all is enough for me:hattip:

What about those formats? What's DTS? Shouldn't I have MPEG checked, as I use/play a lot of mp4 files? Should I check/uncheck any of those?
