Futhermore, I do have to mention that the USB-C port option under settings->security and privacy->exploit protection has to be set to "charging-only when locked" or lower in order to enable the docked speaker audio. (Even though the dock will still charge on the "charging-only" setting)
This is because the port on the back are essentially just another USB connection just like the one on the side of the tablet, so the exploit protection prevents attacks through this port as well.
The four speakers on the sides emit a rich sound however in case you want to set it to charging-only.
I did also purchase the rubbery Google case, the one with the metal prong on the back which will act as a stand and has metal connectors in the back that act as a passthrough for the speaker connection.
Also one more thing worth mentioning is that the dock only has slow charge, which is better for the battery's lifespan. The USB-C port on the side does support fast-charge, both connectors cannot charge at the same time, which prevents overloads, yet OTG (connecting USB pheriperals) and speakerdock-charging do work at the same time like I mention earlier. (As long as "charging-only when locked" or lower is enabled)
