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.
