![]() ![]() it is listed in the System Preferences>Sound>Output window, then we know that the cable between the computer and the sound card is working, and that everything hardware wise is probably OK.Īssuming QLab is still displaying the “No audio device” error after you carried out the above troubleshooting steps, QLab might have forgotten it’s patch to the sound card. If your computer can “see” your Soundcard, i.e. Can you see the make/model of your Soundcard listed in this window? If not, then there is a problem with the hardware connection between the computer and the sound card (such as the cable), or the software driver for the sound card is not working properly (and may need to be reinstalled). ![]() In the window that appears, click on the Sound icon, then on the Output tab. Try turning the sound card off and back on again.Ĭan your computer “see” the Soundcard? Go to the Apple menu in the very top left of your computer’s display, and select System Preferences from the menu. Make sure the sound card is turned on - are there any LED lights or displays on it that should be illuminated? Some sound cards plug into a mains socket, whilst others get their power from the computer they are attached to. It’s not uncommon, particularly on computer systems that are moved around for the cable to pop out a few millimetres, and it can look like it’s connected but isn’t properly inserted. Make sure the sound card is connected to your computer, and that the cable is fully inserted. It’s ridiculous that this step often fixes 90% of problems! The first step to try whenever there is a problem is to shutdown your computer, turn the power off to the computer and any other devices attached to it, and turn it back on. Relatively simple shows might connect using the headphone output socket of the computer. There are also some forms of “virtual” sound card, such as Dante Virtual Soundcard (DVS), where there isn’t a separate hardware device, but your computer is connected to the sound system using an Ethernet cable. Sound cards (aka audio interfaces) are typically a separate hardware device that are connected to your computer using a USB, Firewire or Thunderbolt cable. Plus all those routing, fading, and audio effects you get on Audio Cues? You get those on Mic Cues too.Ĭompatibility: OS X 10.The “This cue does not have a valid audio output device”, “No audio device” or “issue with audio output patch” error message indicates to us that QLab can’t find the sound card / audio interface that it was using to send sound out of the computer to the sound system. The new Mic Cue offers up to 24 channels of live audio inputs. It can even adjust playback rate, to dynamically speed up or slow down your audio, with or without pitch shifting. The powerful new Fade Cue can adjust your audio effect parameters in real time. Add audio effects to individual cues, across all cue outputs, or on your device outputs. You can now apply live audio effects to all your cues: EQ, pitch shift, reverb, and more. Once you master the basics, become a power user with advanced features like scripting, video corner pinning, multi-projector edge blending, audio localization, or even building multi-computer designs by sending commands to other QLab machines on your local network.īattle-tested and used by designers around the world, QLab is the tool of choice in venues large and small. From there, add commands to fade volume, animate videos, or add audio and video effects. Getting started is as simple as dragging in a file and pressing “GO”. Using building blocks called “cues”, you can create sophisticated designs in seconds. A single QLab workspace can control audio, video, MIDI, OSC, and more. QLab allows you to design and operate amazing multimedia performances from your Mac OS X computer. Play back audio, video, and MIDI from a single workspace. Create media designs for theatre, dance, composition, installation, and more. QLab Pro provides live show control for your Mac. ![]()
