标题: 解决更新音频之后，开机出现pop声的问题
解决方法就是先使用老的参数写入，然后使用新的参数再写一次。
static void eamp_poweron(void)
{
printk("sunde:eamp_poweron\n");
unsigned char buffer[5];
.....
//X05 8C
buffer[0] = 0x05;
buffer[1] = 0x8C;
AUDDMA_i2c_write(0x34, &buffer[0], 2);

msleep(50);

late_eamp_write_Biquadsbyte21(); //add by sunde for test EQ 20141229
late_eamp_write_DRCsbyte21(); //add by sunde for test EQ 20141229

//X06 00
buffer[0] = 0x06;
buffer[1] = 0x30;
AUDDMA_i2c_write(0x34, &buffer[0], 2);

//X07 00
