Due to reduced dependency parameters to speed up the apll calculation, the parameters I2S [i2s_num] -> clkm_conf.clkm_div_b = 0; I2S [i2s_num] -> clkm_conf.clkm_div_a = 1; I2S [i2s_num] -> sample_rate_conf.tx_bck_div_num = 8; I2S [i2s_num] -> sample_rate_conf.rx_bck_div_num = 8; is fixed when using ...
