Microphone not working only in DSiWare apps

[OwlicYT]

• Device model: Xiaomi Redmi Note 8 Pro, Samsung Galaxy S23 FE
• Android version: 11

Problem:
When i load the DSi BIOS and try to test the mic in system settings, it makes no sound and shows like no sound comes from the microphone. It happens when i select microphone input to both "device microphone" and "blow".
The same thing happens with every DSiWare app. The microphone works fine only in ROMs.

Steps to reproduce:

1. Install DSi BIOS files and choose them in melonDS.
2. Choose microphone input to either device microphone or blow.
3. Load DSi firmware.
4. Go to DSi settings or any DSiWare app that uses microphone.

Edit: I just checked this on my second phone which is POCO C40 with Android 11 also, and it has the same problem.

Edit 2: I recently bought a new galaxy s23 fe and mic still not working.
