Stand alone Raspberry Pi Bluetooth, Audio Streamer, Dolby/DTS decoder DAC for stereo amplifiers

Hi, I have a question about the DFRobot DAC Audio Decoder Board for Raspberry Pi 3B+/ 4B
SKU: DFR0941. It replaces the DFRobot Expansion Shield x600 for Raspberry Pi B+/2B/3B/4B (Discontinued) SKU:DFR0450, which could decode and playback Dolby and DTS formats through analogue RCA stereo outputs. Can this do the same using a Raspberry Pi. My plan is to share a project where I build a hifi stereo valve amplifier (already in progress), and add a stand alone Raspberry Pi Bluetooth, Digital Service Audio Streamer, and Dolby/DTS decoder DAC, with touch screen interface to the amp. Any stereo amp really, a nice way to recycle old amplifiers for modern applications. Possibly adding a remote control, or smart phone connectivity.

That DAC chip seems to only support PCM audio, so you’d have to rely on software on the Pi to do this, like Kodi or the like.
