If you know how to choose an AV receiver and how to use it, you may find that it’s not providing the audio quality you expected, or another problem has developed. This article will cover some of the most common AV receiver sound problems and how to solve them.
The audio is distorted
If the audio from your AV receiver is distorted, the first thing you should do is check all of the connections. Ensure that the power cord is securely plugged in and that all the cables are plugged in snugly. You must connect all speakers in phases when setting up your home theater system. A positive and negative wire will be attached to each speaker, which you can see through its back panel holes when they’re laid out correctly with colors white ( POS ) or red( NEG ). Some systems will tell you if something has gone wrong on a screen.
If the problem persists, you may need to reset the AV receiver. To do this, unplug the power cord from the outlet and plug it back in once the AV receiver is powered on. Then, press and hold the reset button for 30 seconds.
There’s no sound at all
If there’s no sound coming from your AV receiver, you should first check the volume. Then, ensure that the volume is turned up and that the mute button is not engaged.
To start, unplug your receiver from the power source. Then, check that your AV receiver is connected correctly. The power cable is fully inserted, and the speaker wires have been pushed in correctly. If you’re using bare wire, it should be held down tightly by the binding post screws without too much excess wire.
Once you have checked all the connections, plug your receiver back into the power source and turn it on.
The problem with your speakers could be due to a setting in the receiver. So first, check under “OSD Settings” and try different speaker assignments or play some audio that’s already set up as the default for whichever channel it is on, then check if this makes any difference.
The surround sound isn’t working
If you notice that the volume of specific surround material in movies or TV shows is very low, it may be because there are no apparent indications of how loud that part should be played. To set up your receiver’s setup menu so that each speaker plays at the appropriate level (or just turn up all the volume), go to “settings,” then find “speaker.”
If you are using a subwoofer, ensure that you connect it properly to the receiver and that the volume is set correctly. You may need to experiment with subwoofer placement to find the best location for it.
If that doesn’t solve the problem, it’s time to examine the source material carefully. The question you ask yourself is whether your audio files are capable of playing 5.1 surround sound formats. If they aren’t, then there’s no way to make them work with your current setup. Instead, you’ll need to find new files in a compatible format or invest in upgrading your system.
There’s a delay in the sound
If you notice a delay between the video and the audio, it’s most likely because your TV is outputting a Dolby Digital or DTS signal, and your receiver is not set to decode it. To fix this, go into the “audio” menu on your receiver and look for the “Dolby Digital” or “DTS” options. Make sure that these are turned on.
You can fix the sound and picture not being in sync by using your TV or receiver’s on-screen menu. Look for a feature called Audio Delay. Adjust it by a few milliseconds each time until the sound and picture match. You can find a more detailed guide here. If the picture comes before the sound, you may have deeper problems that require professional help.
The audio is out of sync with the video
There are a few things that can cause this problem. First, make sure the “audio delay” setting on your receiver is disabled. This setting is designed to add a slight delay to the audio signal, which can help to sync up the audio and video.
If that doesn’t solve the problem, it’s possible that your TV is not outputting a Dolby Digital or DTS signal. In this case, you’ll need to use an optical cable to connect your TV to your receiver. It will carry the audio signal in a format your receiver can decode.
It’s also possible that the problem is with the source material. Unfortunately, if the audio and video are out of sync on a DVD or Blu-ray disc, there’s not much you can do about it. However, if you’re streaming content from a service like Netflix, you may be able to fix the problem by adjusting the “audio/video” synchronization setting in your account settings.
