Test the audio outputs
To verify that the OASYS PCI outputs are working:
1. Make sure to turn the volume of your mixer/amplifier before proceeding. If you are using headphones, don't put them on your head!
2. Connect the card's analog out left and/or right to a mixer or amplifier. Even better, connect one of the analog outs to a pair of headphones.
3. Open the Multi named "Continuous Sine Wave.oam," in the folder Korg->Multis->Diagnostic.
4. Within a few seconds, a continuous 880Hz sine wave should be heard coming out of the left and right analog outputs.
5. Gradually turn up the volume of your mixer/amplifier until you hear the sine wave. If you have connected headphones to the card's analog output, put the headphones next to your ear. If you still don't hear the sine wave, put the headphones on normally.
6. If you still don't hear a sine wave, verify that in the File menu, the Play command is disabled, the Stop command is enabled, and the command above the Play command is labeled "Disconnect."

Make sure all OASYS PCI drivers are correctly
installed
The OASYS PCI installs a number of driver files in various locations, all of which are necessary for the OASYS PCI to function properly. If they are not in the expected places, you can easily re-install them using the Custom Install option in the OASYS PCI installer program (MacOS), or by using the basic Windows installer.
ASIO driver
The OASYS PCI ASIO driver is required for ASIO-compatible digital audio programs to use the OASYS PCI as an audio I/O card.
Most MacOS programs require that ASIO drivers be installed in a folder named "ASIO Drivers," in the same level as the application program. If in doubt, consult your program's manual for more information. In some cases, you may need to create and name the folder yourself.
On Windows computers, ASIO devices are entered in the Registry. If OASYS PCI does not appear as an ASIO device, check out the advice under Cannot select as ASIO device in Windows 95/98/ME.
OMS and FreeMIDI drivers (MacOS)
For the OASYS PCI to appear as a MIDI device in a MIDI sequencer, the appropriate MIDI driver - OMS or FreeMIDI - must be installed correctly, in the System->FreeMIDI and System->OMS folders, respectively.
The OASYS PCI Installer will place the drivers in these locations by default.
OASYS PCI Driver, Engine, and Objects Library (MacOS)
These three files are installed in the Extensions folder, within the System folder. They are required for the basic functionality of the OASYS PCI.
Make sure MIDI system is set up properly
Make sure that the MIDI setup (OMS, FreeMIDI, Windows Multimedia, etc.) is correct. Instructions for setting up MIDI systems are included in the OASYS PCI Installation Guide; see also the FAQ articles on OMS and FreeMIDI.
Make sure outputs are set & connected properly
Check the output assignment for the mixer channel. Make sure that you are listening to that output, and that all cables are connected solidly.
If the output assignment is set to Master, then check to see which output is selected as the Master in the Output Busses window, and then, as above, make sure that you are listening to that output, and that all cables are connected solidly.
Additionally, make sure that all cables are connected and seated properly, as described here.
Disable AirPort card (optional) (MacOS)
One user with a G4 dual 533 CPU reported difficulties with the OASYS PCI suddenly going silent. The user found that disabling their Airport card solved the problems.
Check Effects
For various reasons, Effects may sometimes cause the output to be silent. For instance, gate Effects may be silent without a high input level, MIDI gates may be silent without MIDI input, EQ input levels may be turned all the way down, and so on.
As a quick check to see if Effects are responsible for the silence, bypass all effects in the channel or bus.To do this, option-click on any of the Effects slot numbers.
If you hear audio after bypassing, this means that one of the Effects is blocking the audio. In this case, re-enable the Effects by option-clicking again. Then, bypass individual Effects one by one until you find the one (or more) which is responsible.
Mono input insert Effects
If a mono-input effect is being used as a channel insert, and the effect input is set to Left only, no sound will be heard if the audio input is on the *right* channel only.
