Logitech S220 2.1 volume Control pod causes crackly sound

hi there,
The problem is actually from the speakers themselves. If it's not a year old you might want to bring it back to the store where you purchased it for a warranty repair or replacement.
Sadly the problem is inside the speaker and it could be a loose connection inside. If you're comfortable enough you can try to open the speakers and check inside for any loose wires which cause unstability of sound or for any loosed fittings from the magnet.
Hope this helps!

Crackling is usally one or two things my guess would be bad grounding of the amp or bad connection with the jacks or plug it self try to make it crackle on purpose by jiggling the jacks see if it has any effect on the crackling try to narrow your possibilitys

sounds like the sound card board has a short. depending on the notebook, this may or not be replaceable. take it in and see if the board can be replaced

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.

It's just "dirt" on the mechanical part of the volume-control. Either you take the speakers apart, and use denatured alcohol and Q-Tips(tm) to clean that part, or you replace the volume-control, or you replace the speakers.

Hi, the crackling is mostly a result from dust and debris building up on the contacts of the volume knob over the years.
You could try taking some compressed air to the space between the knob and the pod.
and
Sometimes with the power off rotating the knobs from end to end will also help.

Try not to have 100% of the volume. (try 85% instead)

If you use VLC you should be careful and not raise the volume in VLC too much since that software is able to amlify 400% which easy can lead to the cracking sounds from the speaker/headphone you are describing.

usually, crackling is due to 3 things:

1) the soundcard (or sound device you have them plugged into)
The best way to test this is to plug in another set of speakers or a headset directly to the sound
device, and listen. if you don;t hear the crackling, than consider that idea scrapped.

2.) speaker wiring/cables. Check the wiring for cracks/frayed spots. Do you get any crackling during/after you move the wires? if there is ANY change, for the better or the worse, than you have your culprit.

3.) the speakers themselves. when the first two options above are exhausted, there's only the insides of the speakers themselves to blame. you might not have seen any cone deterioration- but other things could happen, such as deteriorating wiring, etc.

for new speakers, they are relatively cheap- Here in Canada at least, I can get a new 2.1 set for anywhere from $25-60. Although, I'd strongly recommend any of the Logitech brand speakers- most models have subwoofers with unbelievable bass (for the price) through them. I myself have the more expensive Z-5500 series from them (5.1), and I've been more than impressed.

mine does that, its complety ok. Just run them at highish volume for about 30 secs should fix them, its just static.

Well gd stuart i think you need some new speakers
