Re: Speakers are making a crackling sound then cut out.
Sounds like an internal loose connection somewhere, possibly anywhere, a connector on a pcb, a dry solder, loose pin on an IC. Tough for an end user to solve this, would entail opening the unit and investigating. I checked the rear panel in the op manual and this model has no ribbon connectors else i'd have asked you to check them.

in radio mode, A./m and F/m
and what about other modes. Cassette, CDDA disc? all crackle
if only radio, then connect a test antenna to the radio
if not the radio is bad, or DC power to the radio is bad.
cuts out, does that mean, just the sound dies in all modes. (left and right speakers)
or the sound and even the dial lights and station tune data is dead too.
It seems you needs more power to maintain the level of good sound.Maybe the maximum volume is 30 - then the mininum is 15 and you can't hear any cracking sound. If you exceed 15 the minimum, as you said starting 17 - 20 you hear crackling sound .Then you reach ,what they called the "cliping level"so much distortion and crackling sound,your stereo too small to accomodate .You must add a power amplifier so crackling will gone and to fit your listening pressure...
Crackling noise and cut outs generally mean that the speaker is torn, or the cone is separated from the driver. This means the speaker is broken irreparably. It sells for $40 now, which means it is not worth fixing. These low cost speakers are built to not be taken apart.
I do also get this same issue, They were working just fine, and 4 or 5 months ago, the right speaker crackles, if i unplug the right speaker all is fine. But as soon as I plug the right speaker in, i get a cracking sound. Have you solved this ussue?
Your speakers are frying, hence the crackling sound, as this is a frequent problem owing to the location of the speaker assemblies and the sound output in an area of the system where the ambient heat exhaust vents are located.
I am a bit confused, though, as to why you get no better sound through headphones or external speakers, since this is not usually the case in this frequently cited problem.
One possibility is that not only are the speakers, but the entire sound output assembly.
Warrantee work if available, if not try a shop where they also sell used Dell computers as they will have pulls that could cut your losses.
It sounds like your volume slider is dirty. Try carefully and judiciously spraying a good quality contact cleaner into the slider and working it. do not use a lot. It only takes a little. Also do not use WD40.
This is a problem with the surround sound processing. Effectively the digital signal is not being processed properly. Since this unit is so new, return it and request either an exchange or at least warranty service. The DSP board will likely be replaced.
Let me know what the Type Numeric Number and Model Number on the bottom of the laptop is. I can look on IBM website and see where the hard drive is in located to the speaker. It has happen on some HP and Toshiba I know from experience where the hard drive causes the speakers to crackle. Not sure why, maybe not enough shielding. The type has 4 Numeric Characters and the Model has 3 Alpha/Numeric Characters.
