I get fainter / tinby / crackely audio out of the left speaker channel, However when CD Direct is on the sound is pretty good (this must be bypassing the dodgy circuit,
also the audio crackles when you turn the bass/treble adjust so I'm guessing it's to do with this circuit.
I tried to get this repaired professionally, but the agent I was using was unable to get service info from the manufacturer

Hi Gareth - I saw you answered a question on an ARM 32-bit Cortex V3.00 barcode scanner earlier and I'm looking for someone to help use one to scan barcodes into a spreadsheet. Sorry for answering off-topic but I'm new to fixya and wasn't sure how to get in touch!
My computer is Gatway bios, P III (Attached a Sound Card its name in my knowledge is not) and i have problem me or my pc this : i not solow my sound card driver is what so plz hep me what is my sound driver or its name thanks my E.mail firstname.lastname@example.org

Get a meter and check the resistance on the speaker. Looks like a speaker may be blown but with the description of the crackle noise from the slide controls you might have a bad pot in the unit or the pot has come loose from the board. This could explain why the speaker blew out
Your speaker may be blown take out the speaker that is hooked up and attach another one a house speaker would even work, and i bet your speakers are blow if not check the wires and make sure you have them connected properly if not check the wires going to the harness and to the speaker and if not i think the radio is fried you can also take a long speaker wire take radio out the dash and run it to the speaker if it does still the radio is fried take it back before 90 days is up!
try to exchange your left and right speaker to confirm. where the cracking noise come? it could be from speaker or your amp itself. 1.if after exchange speaker, it still happen on same speaker then is your speaker already damage could be the cone edge or the coil.
2.If happen on same side from your amp, then that channel output is damage from amplifier.
There could already be a problem with the speaker jack, if only one channel is consistently giving no sound on your system.
Try turning the male (connected to speaker wire) jack and you might hear a static crackle while doing this. If you get both channels to produce sound this way, you already have a failing audio jack, and may need replacement later on.
Would check your balance settings. Make sure your not balanced more to left than right. Next i would try to swap over one of the speakers from right side to left to see if it crackles. If not replace left side speakers.
Make sure your speaker wiring does not come close to the 12v power cable running for your amplifier. If your amplifier's 12v power cable runs on the drivers side of the vehicle, run your speaker cables on the passengers side and make sure your tweeters have a high pass filter to stop any pickup of engine sound (When you are driving you *WILL* notice it at high RPM. a HPF (High Pass Filter) will also stop those nasty hissing sounds on S's.
Generally, crackling noises come from anyplace there is a mechancial connection for the sound signal. The volume control, main/remote speaker switch and possibly the headphone jack. That is where the contacts must be cleaned, but it requires dissassembly. Try operating the main/remote speaker switches, and plug/unplug a headphone several times. I am assuming there is still audio behind that crackling. Are you using both main and remote speakers simultaneously?
Marantz SR 5200/6200 lost audio or crackling on left or right channel except in mode s-direct is now fixed ! The root cause is a defective inegrated circuit on DSP board (the one with digital inputs). To fix it change the chip CS4391 by a new one or better by the improved version CS4392. On my device a capacitor was cut close to this IC : replace one 1uF after changing the IC. For any question search me with my callsing "F5RCT"; i have a spare IC for the one who is able to change it ! I'm amateur radio and engineer
