Was listening to it, turned it off when we left, came home, turned it on and there was no sound. Nothing at all, not even a crackle, speakers are silent. Everything else seems to be working, though with no sound, kind of hard to be certain.
If your head phone is connected to your system there will be no out put to the speakers. Please remove the head phone and try. If this does not solve your problem then there is a possibility of defective audio output IC.
A 6ya expert can help you resolve that issue over the phone in a minute or two.

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.
The crackling sound on the left port of the bass box, indicates vibrating foreign matters inside it. Just open the box and clear it up. Put the sounds on. Listen if the crackling sound is audible. If the result is ok, then, close the box, and everything is alright.. However, if the result is otherwise, then, it is due to a defective speaker that needs to be replaced.
1. remove all external peripherals. 2. use the internal speakers 3. uninstall / reinstall the audio drivers 4. reboot system 5. if still hearing the crackling sound check if cracking sound can be heard only inside windows of even in the bios. 6. check bios hdd if in acoustic mode performance if yes then set it to normal.
Id say you should go see a doctor. But for now id say that you should do your best to not listen to it for a while as it can affect hearing. try to use full on speakers if you can. On you tube there are a few Sub-Woofer sound tests you can do. Try playing one (low volume) and repeat. (not a song one)

If the sound FLUCTUATES up & down, try turning off the AutoVolume in the sound menu.
You didn't say if it's one or all speakers crackling.
Crackling is either a speaker or circuitry issue. Adjust the balance away from the speaker that crackles, if it stops, that speaker is probably "fried". If it still crackles, I'd turn off the speakers and run the sound thru a stereo for the quick, cheap fix.
My Samsung (10+ years old to be fair) crackles due to a circuit issue but if I SMACK the left side speaker (behind which is the sound board and side panel connectors) it stops for a while. Maddening. I think I broke it squeezing it into the furniture it's in, pressing on the protruding RCA plugs. Dumb design.
Could be your head unit or the connection to the speaker may be bad. Also if the wire to the speakers in your ceiling is bare and touching any ground it would interfere. Start by checking connections by playing something and messing with wires. Listen for a difference. Next check by putting the wires that power those speakers in a known working output and listen for different quality
I have a SONY home theater system, HT-C800DP, there is a crackling sound when playing DVDs - it is almost as if the unit overheats. Is there any solution to this? Sometimes I cannot even finish a DVD as the noise gets very loud.
