After years of great listening, the sound coming from my receiver is muffled on all speakers including the center function. I have tested the speakers on another system and they work fine. Any suggestions?

Check to see if the radio is clear. If it is it may be the signal going into the amplifier. if it is muffled as well, depending if you have an Equalizer hooked to the unit. This also could cause the problem. Finally check the bass, treble balance and volume knob but turn them back and forth while unit is on and see if signal clears up momentarily. if this is the case the control knobs need to be cleaned. Also spin the connection jacks {RCAs} in the rear and see if this clears it up. If not you may have to have the unit serviced by a professional.

My left channel in my JVC RX-305 isn't working...what do I do to fix it? When I either push the volume up or down it makes a clicking sound. It was working just fine last night. My right channel is...

Try swapping the speakers or just check the left connections WITH POWER OFF. Disconnect the left speaker completely and see if the clicking stops.

New Yamaha AV Receiver and Tannoy Speakers muffled weak bass only

Maybe some wire is faulty... Try to disconnect everything and connect each speaker one by one, first trying only radio tuner and then trying to connect the TV and other devices. Using that you can isolate the fault into the specific component/wire.

Rear speakers do not sound right they are working but sound muffled or something help??

Rear speakers in 5.1 are no more than sound reinforcement. The brunt of the work is done by the front left and right with most of the burden falling on the center channel.

Muffled sound from rear speakers why watching TV

switch the HDMI cables around to make sure its not one of them, if the problem is one of them it will move with the cable,if no change i would suspect the coaxial cable next.

Make sure center speaker is connected.Look in owners manual to reset, unit might be in an incorrect surround mode.If listening to a stereo source, take it out of surround.

Muffled sounds from speakers suddenly on our boat

Hi airnurse

If you are using a cassette deck for a source of music, then it will have dirty heads. This can be cured by using a head cleaner cassette. Muffled sound from the loudspeakers usually points to a faulty high frequency driver(tweeter). Is the sound muffled on radio or other sources as well. If so, then you have faulty tweeter(s) to any speakers that are muffled.

Of course in saying that, you should check that someone has not just turned the treble control all the way down, or the bass control alll the way up :) Pays to check.

I am more than happy to answer any other questions you may have about it, just give me a hoy :) If you are still unsure, or have problems, then before you give a rating for this advice, please get back to me and we can try some more things.
Thanks for using FixYa, If you consider the advice I have given you as sound, a FixYa rating is a great reward for my efforts to help you. Cheers.
