High-pitched noise when recording Mic with medium Display Brightness

Bug Description

When i want to record something with the built-in mic of the tracker mini, there is a high pitch sound. It gets worse when i up the gain level. Therefore every recording with the mic is useless.

Reproduction Steps

Head to sample recorder and select mic. Add some gain and you can hear the high pitch sound.

I only have my headphones attached and no power supply attached to it.

Hello @miropoly, of course! Thank you for your message.
There are 2 files inside. One without gain, the other one is with 40 Gain. When add more gain, the pitched high tone sound gets louder.

I just ticked with my finger near the mic.

Hi @KrisG, It sounds like a hardware issue.
We can exchange your unit.
Please fill out an RMA application found here: https://polyend.com/rma-application-form/
I will take it from there.
