Hey, Michael,

I split your thread off from Neil's.

In his case, he found that there was a problem with the PCB layout.

I suggest you contact the Taipei office to get them to help you.

Let me know if you can't get a hold of them, and we will work it thru the forum.

I already fix the problem which is caused of improper power trace routing near MCLK.

However, there is another problem. I use two TPA5706 in our board.

While I raise the volume up to the certain level, one TPA5706 is shutdown and another TPA5706 is working properly.

Input voltage is 24V and current is not over 500mA.

any idea for this issue.

many thanks

Michael
