A digital converter box can have defects causing an infinite number of audio problems, which can only be corrected by replacing the box. However, there are also external causes of audio issues that can easily be addressed by the consumer.
Ghosting
"Ghosting" is a phenomenon caused by receiving the same signal twice times, usually because of the signal bouncing off of nearby buildings. Besides causing the familiar "ghost" image in video, it can also cause overlapping or out-of-sync audio with digital television (DTV) signals. Adjusting, relocating or replacing your antenna for a clearer signal should resolve this issue.
Audio Syncronization
In addition to "ghosting," a short break or interference in video when there is none in audio, or vice versa, can cause the audio to be out of sync with the picture. Simply changing the channel, waiting a moment and then going back to the channel will resolve this sort of synchronization problem.
Expectations
Digital-to-analog converter boxes convert digital audio signals to either analog mono or stereo. If you are expecting to receive digital surround sound quality from a digital converter box, you will be disappointed. Additionally, converter boxes do not create stereo. If a stereo audio signal is not transmitted as part of the broadcast, you will not have stereo audio available.
