Summary0001460: No AUX audio issue.
DescriptionI have 1 sample from SKB acceptance inspection.
There is no audio issue from. It looks h/w issue but i want check it in s/w side first.
Please inform me you have something to test in issued box. Below is my test result.

Even though aux device connected, there is no audio from speaker.

Aux plug
cat /sys/class/gpio/gpio503/value => 0
cat /sys/class/gpio/gpio498/value => 0

Aux unplug
cat /sys/class/gpio/gpio503/value => 1
cat /sys/class/gpio/gpio498/value => 1

And, if you think 100% h/w issue, assign h/w guy for this issue.

Hi Wooshin,

The title is "No AUX audio issue.", So, is it no audio when you plug AUX? Could yo please describe the no audio issue more detailed? Then we can help to provide some commands to check if it is a SW or HW issue.

Hi Wooshin,

If no aux is connected, is there still no audio from Speaker?

 Hi Wooshin,

So, it looks like A113X + Wellang AMP is OK.
Could you test if Karaoke APP is OK or not? Because I think, the problem may be related to the ADC IC. And AUX and Karaoke shared one ADC IC. If the ADC IC has damaged, Karaoke should also has problem.

Hi All,

I check HW side, the root cause is register broken, and signal line is opened.
 - R2945, R2946

I will report to the factory another mantis ticket

Thanks

Hi Son,

Thanks for your analysis. Looks like it is a manufacture issue.

Hi Wooshin,
Please close this issue if your HW will create a new one.
