Theoretically, yes – if you can provide MCLK and configure registers via I2C/Slimbus. However, Qualcomm’s datasheet requires proprietary initialization firmware (loaded by the Snapdragon audio DSP). Most standalone designs fail without that firmware blob.
Typically a BGA (Ball Grid Array) SMD IC, requiring professional hot-air rework for replacement.
The WCD9341 is designed for a wide range of applications, including: wcd9341 datasheet
