Hello everybody.
I have a problem with the Allwinner T113-S3-based hardware design.

I have designed my own board with T113-S3, and when I play audio using the aplay command with internal codec, the SoC Temperature increases to critical temperature, and the SoC restarts. The problem persists even when I disconnected HPFB, HPL, and HPR from the board using a cutter.

I have tested the Software(Linux, User applications) with the Mango Pi MQ-DUAL T113-S3, and it is working fine. I think the problem is with the hardware design.

```
