I am using the TFA9896 to collect audio signals over the I2S line, but the collected data sounds really lousy.
The transmitting device has a Clock on 256kHz, and a Frame Sync on 8kHz.
The TFA9896 collects data with a Clock on 1.536MHz, and a Frame Sync on 48kHz.
I am collecting signals on the TFA's "I2S IN1" line with their corresponding BCK, WS and DATA pins.
I should be able to change the Sync frequency on the TFA9896 with I2C, by sending 0x00 & 0x90 to address 0x04, but when I change the configurations as the datasheet says, it doesn't seem to change the actual Sync frequency at all when I measure the signals.
Am I using the correct I2S inputs pins, or are there pins designed for the TDM configurations?
Am I using the correct configurations to change the frequencies?
