Troubleshooting
There are Interruptions,
Dropouts, or Other
Problems in the Sound
During Playback
Could you have connected/
disconnected another USB device,
such as a memory key? Dropouts may occur during playback or recording if you connect/disconnect another
USB device (such as a memory key), or switch a device’s power on/off at the same time
that the V-STUDIO 20 is being used.
Are you using a hard disk that is
connected via USB?
Data transfer using USB could get congested if you use the V-STUDIO 20 and a USB-
connected hard disk at the same time. As a result, the data transfer speed for the hard
disk could be significantly reduced. As a storage location for the audio data that you
record and play back, you should avoid using a hard disk that is connected via USB.
Did the dropout occur immediately
after the system started up, or after
it woke from sleep? Dropouts during playback/recording sometimes occur immediately after the system
has started up, or after it has woken from sleep. Wait for a while, then try the playback/
recording again.
Windows Update/ Microsoft
Update Use Microsoft Corporation’s Windows Update or Microsoft Update to update your
system to the most recent state.
“Audio Buffer Size” in the setting
dialog box
See Audio Driver Settings (p. 24)
I did not see any meters move in
Guitar Tracks or hear any sound
The most common cause of this is if the playback device is not set correctly.
In most cases, you can correct this by following these steps:
• On the Options menu, click Audio to open the Audio Options dialog.
• Make sure the driver mode is set to “ASIO”
• Make sure you have “VS-20” selected for both playback and recording
devices.
If you do not see an option for VS-20, check the settings described in “Audio Driver
Settings” (p. 24).
I can see meters moving in Guitar
Tracks, but I don't hear anything
• Make sure the “Output Level” on the VS-20 Hardware is turned up
• Make sure the “DAW Output” on the VS-20 Hardware is also turned up
Audio starts to play, but I get a
message that says DROPOUT or
AUDIO STOPPED either in a dialog
or across the bottom of the screen
A dropout is a symptom of audio hardware when it is unable to pass audio data fast
enough. There are a few things that may alleviate this:
• Check the settings described in “About Mixing Latency” (p. 46)
• Ensure nothing else is trying to use the sound device at the same time.
Guitar Tracks will perform best when there are no other software
applications attempting to use the sound device, such as web
browsers, video players, instant messaging clients and other sound
applications.
Clicks or pops may occur in the
sound if a LAN is operating Try disabling the LAN in Device Manager. If this eliminates the clicks or pops, you may
be able to solve the problem by updating your LAN driver or BIOS.
Could you have connected the VS-
20 to a USB hub?
Try connecting the VS-20 directly to a USB connector on your computer.
Playback Halts Midway,
and Subsequent
Playback is Not Possible
While you were using the
V-STUDIO 20, could your computer
have performed a task with a heavy
processing load, such as accessing
a DVD-ROM drive or the network?
If a heavy processing load occurs while the V-STUDIO 20 is being used, it may not work
correctly. In this case, stop playback, and then start playback once again.
If you are still unable to play, close all software that was using the V-STUDIO 20,
disconnect the USB cable from the V-STUDIO 20 hardware, and then reconnect it.
