7. Releasing a Corrupt Device Driver
After launching the audio host application, there are certain conditions that could arise leading to a series of
error messages relating to the state of hardware or its associated device driver. If the host application has
already been configured for a particular device driver, and if its associated hardware is not present or turned-
on, you will most likely be presented with Error dialog i.e., “Error opening audio device” or “Error opening
audio output device”.
However, there is an error, “Error setting up output pin” - that is most likely related to a corrupt driver that
was not installed, removed or released correctly. When a device driver is in this state, you may not be able to
remove it, as the computer will report “device driver in use” or something along those lines. In the event that
a device driver becomes uncooperative, there are steps you can take that will very likely resolve this issue.
1.
Power-down the I/O hardware device and proceed with audio application launch. You may leave the I/
O device physically connected to the USB or firewire port.
2.
Once the audio application is fully booted, go to Setting/Audio Devices or your applications equivalent.
Under Wave Device - switch to Direct Sound. This will release the device driver in question. At this point
you can open and play a project – making sure there are no other issues unrelated to device drivers.
3.
While in Direct Sound mode, power-up the I/O device and wait for 10 or 20 seconds. If you have an
opened project, be sure it is not in Play.
4.
In Wave Device - switch to the Onyx driver (or the device driver in question) and wait a few moments.
The device driver should now be re-engaged. Go back to your project and press Play.
Some audio applications have a function called “Release Driver” – use this if available. If you are moving
between apps frequently, you might want to always choose Direct Sound (or None) before closing or minimiz-
ing – this will also avoid problems when starting an audio application in the event that Onyx, Spike or
Link.USB is not connected to your computer.
Remember – if a driver is in use or in a corrupt condition, it cannot be removed or reinstalled until it (the
device driver) has been released. All together now, “
Please release me – let me go…
