The buzzing noises definately sound like they are coming from the speakers
yes it does seem like that is happening
it was made back in march 2013 and it is a windows 8 samsung laptop
.Unfortunately what you are describing sounds like a damaged speaker. Some Samsung machines have a 2 year warranty so you may be able to get it fixed calling: 1-800-726-7864 or 0330(NNN) NNN-NNNNin the UK. Unfortunately to fix this the damaged speaker would need to be replaced. If you have any questions at all click on reply to expert and let me know.
