Special Notes
Although some sellers describe QCC5125 boards as โlosslessโ, the QCC5125 itself supports aptX/aptX HD/aptX Adaptive rather than Qualcomm’s Snapdragon Sound CD-lossless feature. Qualcomm’s own comparison lists CD Lossless with Snapdragon Sound as unsupported on QCC5125.
If your particular board also supports LDAC, that should be stated as a board/firmware-specific feature, not assumed from the QCC5125 chip alone. Some QCC5125 decoder boards do advertise LDAC support.
