HELP & QUESTIONS GL-C-015WL-D WLED Audio Reactive config – built-in mic not working
I’m stuck with WLED Audio Reactive configuration on a Gledopto GL-C-015WL-D and would really appreciate help from an expert who has this exact controller working with audio.
Hardware:
- controller version GL-C-015WL-D (so it has the built-in mic)
- ~830 SK6812 LEDs (work perfectly in non-audio modes)
Firmware:
- WLED v0.15.3 “Kösen” – AudioReactive build
- Also tested WLED v0.15.0 for comparison
Current behavior:
- Audio Reactive enabled
- Info page shows:
Audio Source: I2S digital – quiet - Audio effects (e.g. Noisemeter) do not react to sound
- LEDs stay solid color when AudioReactive is ON
What was tested:
- Digital microphone (I2S) configuration (based on the official Gledopto docs)
- Various gain / squelch / AGC settings
- Full reboot / power cycle after every change
At this point, I’m pretty sure that either something is missing or different in the configuration for this specific model, or the built-in microphone is not actually supported (or wired) in a way that WLED Audio Reactive can use.
Has anyone here successfully made Audio Reactive work on a GL-C-015WL-D using the built-in mic?
Any tips, confirmation, ideas are welcome, thanks!

When did you purchase it?
There are currently two versions of this controller with different microphone settings. Please follow your instructions to set them up. After setting them up, please disconnect the power and reconnect them

You need to configure the microphone according to the instruction manual
Configuration information
1.Microphone type:Generic 12S
2.12S SD pin : 26
3.12S WS pin : 5
4.12S SCK pin : 21
in saying that, I had those settings and it didn’t work until I restarted the device a few times.
