Setting up an additional device (USB microphone) for Audio visualization in HyperHDR

[PapaUte]

Hello guys,
I have setup Homebridge and HyperHDR on Raspberry Pi 3B and built a Ambilight-setup and it works great :)

I would like to setup an additional device (USB microphone - Texas Instruments PCM2902) to capture audio / music from another source (HiFi Music system with Wiim Ultra and Moon Amp - which are not connected in any way with the Raspberry / HyperHDR) and make HyperHDR visualize the audio.
Is there a possibility to do this in HyperHDR?
In the effect section of HyperHDR, I can only choose the Video-grabber as audio device, but not the connect USB-microphone in the Raspberry Pi 3.

Hi
Is Alsa command line tool seeing your microphone as an input device? HyperHDR detects connected devices during startup: if the device (microphone) is not available at that time or its installation is in progress, it may happen that in such a case you will not see it on the list. Then it is enough to restart the HyperHDR service using systemctl (https://github.com/awawa-dev/HyperHDR/wiki/Installation#linux) or delay the start of the HyperHDR service a little.

Thank you for your reply. Stopping HyperHDR and starting it again helped: The USB-device is now displayed in the Web-GUI of HyperHDR and the visualization of music works great!

Is there an option to make the HyperHDR-service start with a small delay? What time would be sensible? 5 seconds?

You must edit (as root) /etc/systemd/system/[email protected] file and add sleep 5 && before /usr/bin/hyperhdr. Then sudo systemctl daemon-reload and restart the service.

Thank you very much for your support - this helped and works fine now! Amazing :)
