Hey all,
This may be a general Raspberry Pi problem, but I haven't found an answer on a different forum so I though I'd ask here.
I'm working on a headless Pi based DMX foot controller.
The USB mic works great when the Pi is connected to HDMI/TV, however if I boot with the HDMI unplugged the audio trigger will never initialize. The mic is still selectable in the web configuration,
Im using a "Rock Band" USB mic with a powered USB hub that also is powering my NanoKontrol and Diy DMX dongle. (this one: http://stevenbreuls.com/2013/05/diy-usb ... -under-10/)
currently on 4.8.5 GIT
any ideas? Thx in advance!

USB Mic not working without HDMI plugged in.
Just an idea of some thing to check. when I was poking around on my Pi, I think I came across a sound over HDMI option. I think this was a choice between HDMI or stereo socket, may be if it is set to HDMI and there is nothing attached the sound module isn't initialised.
I would like to point out that I am no Pi expert, but that this is just an adea floating around my head

I think it has something to do with that. I can't seem to figure out how to configure it though.
I know little about Linux and even less about Raspberry Pi.
I've tried editing /boot/config.txt , in order to force HDMI, but nothing seems to happen.
I am missing something? or does QLC+ not use /boot/config.txt?
also, just an fyi, plugging just an HDMI cable in (and not into TV) does not work.

I got raspi-config installed (just barely, but I'm learning!)
It gives me an error when trying to configure audio.

Well, in theory a USB mic (input) should have nothing to do with HDMI/Analog (output)
I have a cheap USB card that I tested on the RPi a while back, so I'll try again to see if HDMI makes any difference.
One thing though, the multimedia part on the Pi is not 100% guaranteed to work.
Videos don't work yet and the audio input requires a lot of CPU and might cause unexpected behaviours.
In any case, please specify the RPi model you're using. Now that version 2 is out, I need to know exactly on how much power QLC+ is running.

I'm on the previous version, raspberry pi 1 B+ (bought it 3 days before the 2 was announced)
thanks!!!
thanks!!!
soooo...
I dont know where I went wrong, but I got frustrated and decided to start over. I created a brand new project with only one audio trigger and it works now headless. The previous project does not.
have I lost all the functions? is there a way to export?
thanks all for the help.
