    It still does it regardless of whether I use the internet or not. I have BitTorrent but it is not currently running. I do not use all of these applications at the same time.

My Korg c15s has a lot of grating staticky noises when played ....I'm told it cannot be repaired as Korg no longer makes parts for this model?


I have a Korg C-15s and also experiencing loud crackling sounds when I turn it on. The problems seems to be either the sliding volume control or the amplifier itself. Honestly though, I believe the issue is the volume control. I opened my piano to get a closer look and attempted to clean the contacts on the volume. Unfortunately after cleaning the contacts, the crackling sounds became somewhat worse. After I turn the piano on, the volume control is generally rendered useless......volume set to low volume and the noise is quite loud and other times the volume control is set high and get very low volume crackling noise. No real consistency. The noise does diminish after a few minutes but so does the piano sounds to an inaudible level. There were a couple of instances where I turned it on and surprising enough, no no noise and perfect sound. For these reasons I believe the issue is within the volume control and not so much the amplifier. I have an electronics background and noticed that the volume control is very unique in design and is not something that can be substituted with another volume control from other sources.

My recommendation is to check the sound quality of the audio from the RCA L/R audio outs on rear of the piano by connecting to a stereo receiver. If it sounds fine you're in luck. If the crackling sound does not diminish after a few minutes like mine does, I would suggest disconnecting the internal speakers and using the audio out only. You can connect a pair of studio monitors or high quality computer speakers, preferably with a small subwoofer to deliver the full audio range and deeper tone of a real piano. I'm currently using a basic pair of Logitech computer speakers and is quite acceptable until I can afford a high quality set of monitors or relocate my piano closer to my high quality Yamaha receiver.

I hope this info helps a bit.

Intermittent crackling sounds DPR 1005


This is an obvious thermal problem. Use circuit cooler to isolate the bad part. It could also be a crack in a circuit board.

Alternate warming with hair dryer and cooling one component at a time while listening for the noise.

Crackling noise from subwoofer????


sgangsta91,

i think your speaker cannot support the sound that your computer produce. it means to say that, they are not compatible. specially when your computer sound interface that you used is 5.1 or 7.1 interface but your speaker specs is only for generic sound, you really hear a crackling sound and more if you set to higher volume.

but it can help if you only set your computer interface to generic sound or set only in lower volume it can help. because if you continue that way, your speaker can be seriously damaged that even at the lowest volume can hear the crackling sound.

or if you really want a fine good sound system then, buy a speaker that can interface with 5.1 or 7.1 or see manuals of your computer/motherboard. for recommended specs

I have a HP pavilion dv7 1016nr. Listening to music through it sucks. I get a crackling sound on every track. I've gone back and played the track again to be sure it isn't my files. I.ve tried my music...


I have encountered several HP Pavilions with similar problems.

First of all I would suggest muting any input sources in windows volume control. (microphone (mic); line-in; auxiliary; etc.)
P.S. Voice communication software like Skype work better with the micophone muted anyway, because that way the sound recieved by the mic does not get echoed through your speakers.

If that doesn't help then I suggest updating the audio driver. The latest one can be found here:

Hope that helps.

Akai PT5598HD 55 in. Rear Projection


Something like this Id have someone who knows there way around electronics, a qualified tech or someone you trust really well :-) Does the crackling affect the TV picture at all ? My first guess would be dust and or dampness on the audio components. Sometimes this can conduct electricity across small pc chips and reak all sorts of havoc. I had an old Tomas electric organ once, and it actually caught fire because two speaker wires were rubbing together and eventually wore thru the insulation and shorted out, but it was also making alot of crackling and static noises. Try raising and lowering the volume low to high and high to low and see if the crackling noises gets worse. Some audio amplifiers put out quite a bit of power, so I wouldnt trust leaving the TV on without a fire extinguisher handy.

Crackling sound


Hi, the problem could be in your phone line, A solution I found was a free download from CNET called "Noise Free Voip"
This is a small download that runs with Skype etc and works very well at reducing outside noise factors.
