    First of all, please get a proper connector, or do a chip-off operation and save yourself a headache.

    I tried to go the easy way and stuffed the chip into the clips, which didn't work and the read became really unreliable, even with SiberiaProg, which pretty much read whatever I threw at it.

    The good dump only appeared after I physically soldered everything to the pins. Now I am getting some audio, but it's very distorted. ADPCM?

    The manufacturer of the main chip, TRSF16128B, is called Tritan Technology, and their site says that this chip does support "ADPCM audio". There is no detail on what version/kind/type/etc of ADPCM they're using -- they might be using Yamaha ADPCM for all we know.

    All of their example codes, datasheets, product catalogs, and other valuable information are locked behind the login prompt. Unless someone graciously gives me access to this datasheet and "TSP" program which would hold the secrets to the codec, I would need to blindly shoot and see what sticks.
