documentation for adding such a printer (actually, print driver) and configuring it

properly. A commonly-used print driver is the Microsoft XPS Document Writer,

which is available as a default on operating systems from Windows XP forward.

7. Make sure that you have adequate hard disk storage for files XStudio generates. XStudio

can generate a significant amount of event data as system performance and actions are

tracked throughout the day. As a default, XStudio keeps 14 days worth of daily event logs

(as does XEngine) and the files can approach 3 MB in size or larger for each day's event

log. Database files can also be significant in size. Depending on the number and types of

audio files you are playing and whether or not they are located on a local drive, you may find

that you are running short of disk space.

6.1 Audio Playback Problems

If you are having trouble with audio playback and are using XEngine as the host audio server, here are

some items to check:

1. If audio files you are attempting to play back are apt-X™ files, make sure you have installed

and licensed the apt-X support files. XEngine will play PCM (linear) and MPEG-2 files

without additional software, but apt-X files require additional software that must be licensed.

See the section on Installing XStudio for further details on making sure you have apt-X

functionality installed.

2. Make sure the audio path is set properly in preferences and that the location is accessible to

the PC. You may have that path set correctly but not have privileges in the designated

folder. If you have the Generate and Use Local Inventory option set and do not have at

least Read privileges in the audio folder, the XStudio inventory list will be empty, too.

3. Make sure that you have the proper audio output devices selected and that it is present in

the system. This sort of problem most commonly shows up when using a PCMCIA or USB

sound card as the playback output device and the device has been removed or

disconnected.

4. If audio appears to be playing, but you cannot hear it, check to ensure that you have

connected speakers or the external mixer to the correct audio output port(s) or jack(s) on

your PC.

5. If audio levels are too low or too high, either change the software volume setting on your PC

or adjust the gain level on your external mixer.

6. If you are getting unwanted sounds during playback, it is likely that the audio output device

you have selected for XStudio is the same device being used by Windows for "system

sounds". To prevent this, turn off sounds associated with Windows events in the Audio

Properties | Sounds section of the OS.

7. If the audio is a LAN server, ensure that you have enough data bandwidth on the LAN to

support direct playback from the server. This problem most commonly manifests itself as

what is referred to as "audio skip" or audio "drop-out". Check to be sure that some other

application on some other PC is not "hogging" all of the network bandwidth. If your audio

library consists of mostly PCM (linear) files, this will create a larger network load than either

MPEG or apt-X audio. This problem can be mitigated by increasing the number of audio

buffers used by XEngine in Preferences on the Audio Properties page.
