Atom 3 latest firmware as of 2023.02.17:

Note that for Xiaomi 13, iPad Air (5th generation), or iPad devices that do not recognize Atom 3, you need to flash the special firmware, and the sampling rate only supports up to 192kHz. (This is because the Type-C port of these devices does not support high-bit-rate output). The ROM with "PAD" in its name is the one you need.

The ROM with "BassBoost" in its name is the low-frequency enhanced version.
