Draft - do not merge - Audio bridge between i2s mic and uac2 gadget #102

Awesome. This is one rather interesting PRs. How did testing go? |
It kinda works? I've successfully used the microphone but it also introduces some unusual behavior that I've detailed here. |
|
Ah, thank you! Sorry I missed the reply on the linked thread. Please help by cleaning it up and allowing a config change to forward the audio. Since this hardware is less common, the better way to deal with this is to disable it by default and allowing enabling it with a sentinel file. |

I am using this mic. Earlier, when testing with a KDE Neon host on Audacity, I was getting inconsistent samples of sound. Now, there is no sound detected with Audacity or arecord. I have verified that the mic works and have re-flashed the image, still nothing. Is there anything that can be done? |
|
@jeztek, thanks for replying and spending time on this. I have been getting inconsistent sound samples using the PR zip file (git clone wasn't getting the modified version for some reason). To verify the mic was working, I used RPi OS and the documentation. I am using a single mic. |
|
EUREKA! I changed board/audiobridge.sh so that:
instead of 85%. It works great now. I tried 55% and above, but that is when the problems start. I can record with Audacity, but not arecord for some reason. |
|
Is there any way of turning off the audio output? Doing so may help reduce the artifacts on the video feed. |

The microphone isn't working in Windows 10. The mic does appear in device manager under "Sound, video and game controllers" as "Source/Sink", but I am getting the error "This device cannot start. (Code 10)". |
Creates an uac2 usb audio gadget and uses alsaloop to bridge audio between it and an i2s microphone
