我们通过规格书，配置了44.1k的采样率，然后边录边播，会时不时出现破音。请问怎么解决？我贴出配置的寄存器和电路如下：
snd_soc_write(codec, 0x00, 0x00);//切换寄存器页到页0
snd_soc_write(codec, 0x01, 0x01);//软复位
//2
snd_soc_write(codec, 0x04, 0x03);//set pll=mclk, codev_clk=pll
snd_soc_write(codec, 0x05, 0x91);//set p=r=1
snd_soc_write(codec, 0x06, 0x07);//set j=7
//d=5264
snd_soc_write(codec, 0x07, 0x14);
snd_soc_write(codec, 0x08, 0x90);
//snd_soc_write(codec, 0x05, 0x91);//
snd_soc_write(codec, 0x12, 0x88);// NADC = 8
snd_soc_write(codec, 0x13, 0x82);// MADC = 2
snd_soc_write(codec, 0x14, 0x80);// AOSR = 128
snd_soc_write(codec, 0x1b, 0x0c);//
snd_soc_write(codec, 0x1d, 0x07);
snd_soc_write(codec, 0x1e, 0x82);
snd_soc_write(codec, 0x3d, 0x03);
