The DD+ extension bitstream is used on players that support it by replacing the rear channels in the 5.1 setup with higher fidelity versions, along with providing a possible channel extension to 6.1 or 7.1. The complete audio track is allowed a combined bitrate of 1.7 Mbit/s: 640 kbit/s for the AC-3 5.1 core, and 1 Mbit/s for the DD+ extension.

Advanced Audio Coding is designed to be the successor of the MPEG-1 Audio Layer 3, known as MP3 format, which was specified by ISO / IEC in 11172-3 ( MPEG-1 Audio) and 13818-3 ( MPEG-2 Audio). Blind tests in the late 1990s showed that AAC demonstrated greater sound quality and transparency than MP3 for files coded at the same bit rate.
Bitstream vs. PCM for Audio – Which Is Better?
https://hometheateracademy.com/bitstream-vs-pcm/

Compatibility with devices and supported frequencies are bigger factors to consider than sound and transmission when choosing between PCM and bitstream. Also read: 2.1 vs. 5.1 vs. 7.1 Surround Sound
PulseAudio - Official Kodi Wiki
https://kodi.wiki/view/PulseAudio
Passthrough Mode Used if you want to passthrough (bitstream) AC3, DTS, and EAC3 to an AVR or other device. In order to allow passthrough to work with PulseAudio then it MUST be set to use a 2.0 channel configuration, despite the 2.0 setting this will still allow 5.1 audio from AC3, DTS, and EAC3.
DTS-HD Master Audio - Wikipedia
https://en.wikipedia.org/wiki/DTS-HD_Master_Audio
DTS-HD Master Audio (DTS-HD MA; known as DTS++ before 2004) is a multi-channel, lossless audio codec developed by DTS as an extension of the lossy DTS Coherent Acoustics codec (DTS CA; usually itself referred to as just DTS). Rather than being an entirely new coding mechanism, DTS-HD MA encodes an audio master in lossy DTS first, then stores a concurrent stream of …
