    mute your mic, sometimes this can cause interference in your audio signal. I am not sure if this will solve this problem, so I will leave this as a clearifcation.

How do I get rid of terrible crackling when playing back?


Simply put: you can't. There are audio programs out there that can help reduce the crackling / noise, but it will never be perfect; the cure might be worse than the ill.

A techn-savy person could have a try at it; lot's and lot's of time required, or - but could be expensive - you could contact a sound-technician and have a pro give it a try.

Audio problem streaming media via ROKU and RCA players. Constantly have to adjust volume to hear them talk, but then the music/sound effects blast you out.


It sounds like you're using a set of stereo speakers to play a surround sound output. I would try going in the TV menu and turning off surround sound

The speakers are making a crackling noise that is not effected by the volume


Check the speakers first. If the voice coil of the speaker has any fault, the speaker should be replaced. Connect an other speaker in place of present one, and see whether the crackling sound occurs with it too. If yes, the audio output board to your TV have the fault, and it should be replaced.

Crackling from set volume button makes no


Sounds like a loose connection with one of the audio/video cables inside the TV or a short. Contact a qualified service technician to do the fix.

Cakewalk Sonar - Edirol UA-1000 crackles on playback!


That's a latency issue it sounds like.
There's a slider under "Audio" .

Move it in increments towards "slow", test it as you go.
Leave it at the highest setting possible that doesn't crackle.

I've heard this so bad that it sounds like a gun going off.
It scares the Hell out of you when it happens !

My amp works but my sub doesn't...!!!????????????


Whats the condition of your amplifier? New , Used, Old?

 

You might have a blown channel off your amplifier, this may cause little or no sound. You will have some distortion, crackle sound and then maybe nothing at all. What kind of subs are you running to it? Make sure the subs arent blown and check the voice coils to see that they are not torn off the subs , these are the 2 little silver or copper wires that are connected from the speaker connectors to the sub itself.

 

Let me know what happens?

Vizio 42" LCD HDTV audio issues


First of all go into the audio menu settings and turn off the "surround" feature off and that should fix the voices/music differences. Does the craking sound appear while watching any sorce such as cable box,sat rcvr or DVD player? If not isolate it to that input and maybe that device is giving the problem.
