My Edifier M60 speakers suddenly started having sound issues after working fine before. I checked the cables and settings, but the problem is still there. I need help figuring out what caused it and how to fix it so I can get them working properly again.
Start with isolation. You need to find out if the fault is in the speakers, the source, or the cable.
-
Test a different source.
Use your phone with Bluetooth, then use AUX or USB if your M60 supports it. If Bluetooth sounds bad too, the issue is inside the speaker system, not your PC. -
Swap cables.
A bad 3.5mm or RCA cable causes crackling, low volume, one-side audio, and dropouts. Cables fail more often than people think. -
Check left vs right.
If only one speaker is bad, swap the speaker connection if the model allows it. If the problem stays on the same physical speaker, that speaker or its amp section is the issue. -
Power reset.
Unplug the speakers from wall power for 10 to 15 minutes. Some Edifier sets glitch after power spikes. Sounds dumb, but it fixes wierd behavior sometimes. -
Listen for symptoms.
Hum or buzz, often power supply or grounding.
Crackle when moving knobs, dirty volume pot.
Low bass and thin sound, partial amp failure or bad input cable.
One speaker dead, blown driver, bad amp channel, or internal wire loose. -
Check the basics on the speaker itself.
Input mode selected right.
Volume knob not dirty or failing.
No headphone jack stuck in a half-detected state, if your unit has one. -
Try a different outlet.
A noisy outlet or cheap power strip causes hiss and hum.
If the issue started out of nowhere and happens on every source, odds are the internal amp or power supply is failing. Edifier powered speakers do this sometimes after a few years. At that point, if you’re under warranty, contact Edifier. If not, repair only makes sense if the cost is low. Opening them up is a pain, and replacement boards arn’t always easy to get.
If cables/settings are already checked, I’d look at two things people skip:
-
Windows/audio driver weirdness.
If you’re on PC, disable all “enhancements,” spatial sound, loudness EQ, and any app-specific effects. Also set output format manually to something normal like 24-bit/48 kHz. I’ve seen speakers sound busted when it was just the driver freaking out after an update. -
The source level might be clipping the speaker input.
A lot of powered speakers get ugly if your PC or phone output is maxed. Try source volume at 60 to 80% and control loudness from the speaker itself. Distortion can sound like hardware failure when it isnt.
Also, check if the problem changes after the speakers warm up for 10 to 15 mins. If it starts bad then improves, that points more toward aging components inside, usually caps/power section. If it gets worse as it heats up, also not a great sign.
I slightly disagree with @viajeroceleste on repair being rarely worth it. If it’s just out of warranty and the fault is the power board, some local electronics shops can fix it pretty cheap. But if the amp board is toast, yeah, replacing the whole set is often less pain.
One more thing: factory reset if the M60 app/settings allow it. DSP bugs do happen. Weird, but real.
I’d test the speakers completely away from your current setup before assuming the Edifier M60 itself is dying. Different wall outlet, different source, different input type if available, and ideally one speaker at a time if the design allows it. That isolates house power noise, a bad DAC, or a flaky source device fast.
A thing I slightly disagree on with @viajeroceleste: if the issue is only on one channel, I would suspect the speaker or interconnect before software. Software problems usually hit both sides equally.
Quick fault split:
- Buzz/hum only: likely power or grounding
- Crackle when touching knob/cable: dirty control or bad jack
- One side weak: bad cable, amplifier channel, or driver
- No bass / thin sound: partial driver failure or DSP issue
- Audio cuts at certain volumes: protection circuit or failing power supply
Try a low-volume sine sweep or simple left/right channel test. If one frequency range rattles badly, that can be a loose driver or cabinet vibration, not electronics.
Pros of the Edifier M60:
- compact and clean sounding
- easy desktop placement
- usually good value
Cons:
- powered speakers are harder to service than passive setups
- if internal amp/DSP fails, repair can be annoying
- some issues can masquerade as source problems
If they are under warranty, stop troubleshooting after basic isolation and claim service. Opening powered speakers too early can make support harder.
