audio problems

 

no audio

several things to try:

  • wildly turn the volume knob. if speakers make hissing and sputtering noises and eventually quiet down, it's your volume knob. replace the speakers. the volume knob will just get worse and worse, and it doesn't take long before a year goes by and you find you need to just get new speakers. this is caused I think by the carbon film used in many potentiometers. maybe it just wears through or gets dust in it or something. or maybe it's humidity. I don't know. but it happens more often than you might think.
  • do you have the speaker plug in the right jack?
  • is the volume in the computer turned up?
  • is the audio in the computer configured to 9output to that channel that the speakers are plugged into?
  • are the speakers in the audio config set for the kind of speakers you have (like 2.1 for subwoofer+2 satellites)?
  • are the speakers plugged into power made for the speakers (they do have a wall adapter or some sort of power plug that goes into the wall)?
  • try repairing your filesystem and reinstalling audio drivers. sometimes, this fixes the problem, and it's free.
  • newer drives may also fix some problems. they are available from the computer or motheboard manufacturer's web site.
  • if none of these work, replace the speakers, they may just be bad.
  • if replacing speakers doesn't work, install a usb audio interface

hissing, sputtering volume knob

wildly turn the volume knob. if speakers make hissing and sputtering noises and eventually quiet down, it's your volume knob. replace the speakers. the volume knob will just get worse and worse, and it doesn't take long before a year goes by and you find you need to just get new speakers. this is caused I think by the carbon film used in many potentiometers. maybe it just wears through or gets dust in it or something. or maybe it's humidity. I don't know. but it happens more often than you might think.

speakers sound like sand is in them (hissing/scratching) regardless of volume knob

your speakers are probably blown. solution: get new speakers. if it's a phone, get a new phone/speakers $400-900 or get the phone's speaker repaired $70?
