Thanks, good to know! I had only figured out that it was somehow related to powerdown and/or soundlink.
So it seems to be simply soundlink related (assuming that the "radio" is the same as the "soundlink" feature).

Here are two photos of a BSC-1J5M-01 with the Datapak connector removed, for reference.
(Needed the connector for something, figured I’d photograph the board)

A photo of the SameGame character cartridge PCB. Fullsnes.htm seemed to be missing verified info on these, so uploading if it's of any help.

I actually didn't say it much, but bit 0 of $2194 does enable the stream registers. In fact, I heard even a static sound when I enabled it (when SPC700 is unmuted... which I did).
Reading $218B (or $2191), because it isn't initialized properly, reads garbage, and the data is ORed at $218D (or $2193), that's done no matter what... but when I read it when $2194.0 is set, it does read once and then resets itself to 0x00. But when it isn't, when that bit is unset, it does not reset. That bit is simply the one that enables stream registers.
