Audio Input

[Peetem]

Hey -

Still using an older version for the Pi as I tweak everything and test it out.

One question that has come up - how do I provide audio input to the Pi? I'd like to test the feature that allows for input to control functions/DMX/etc.

I have a USB audio input device, but the Pi / QLC+ doesn't seem to recognize it.

I've got pretty much everything else to work (although the screen size doesn't change, although I have adjusted it via the tools menu) - and its great! But I need to get this last feature to work before I switch back to the new release and test it.

Any help would be super appreciated!

Thanks!

On the I/O tab, right side you'll find an "Audio" tab. This should list all available devices and let you check the ones to use for Input and output, separately.

The Raspberry Pi QLC image is a modified Raspberry Pi OS Lite, which is based on Debian Linux, and as such it uses the ALSA audio system. As long as your USB device is supported by ALSA and detected correctly, it should be listed on that tab.

If you can access a terminal prompt, the command "cat /proc/asound/cards" lists all detected audio hardware and subdevices, and you can see your USB devices via "lsusb".

Yeah, I’ve tried all the audio inputs. The USB input worked with other applications on the Pi, so no idea why it’s not working with QLC+.

Will try another adaptor.

QLC+ is based on the Qt libraries and the Qt libraries make use of gstreamer for the multimedia part.
There might be a gstreamer plugin missing even though I'm pretty sure I have installed all the necessary packages
