Acer Swift Go 14 (SFG14-73)-How to fix speaker crackling sound?

Santhosh2003

Hi everyone,

I’m using an Acer Swift Go 14 (SFG14-73) laptop, and I’m having a problem with the left speaker.

Issue:
The left speaker crackles, especially when the volume goes above 75%. The right speaker is working fine. There’s no crackling when I use headphones, so the problem seems to be only with the left built-in speaker.

What I’ve tried:

Updated audio drivers
Disabled sound enhancements
Changed audio settings (sample rate and bit depth)
Updated BIOS and Windows
Tested different apps and videos

Still, the crackling continues only on the left speaker.

Has anyone faced this issue with the same model?
How to resolve this?
Please let me know if you have any suggestions or solutions.

Thanks in advance!

Please try these suggestions.

The issue of crackling in the left speaker, specifically at higher volumes, likely stems from a loose connection or a faulty component within the speaker itself or its wiring. Since headphones work fine, the problem is localized to the built-in speaker system. Ensure the speaker wires are not near power wires or other devices that could cause interference.

Dust and debris can accumulate on the speaker drivers and affect sound quality. Asurion recommends cleaning the speaker grille and drivers with a soft brush or compressed air.

Ensure the speaker cables are firmly connected to the amplifier or sound card. Disconnect and reconnect them to make sure they're seated properly. If you're comfortable with basic electronics, check for loose connections within the speaker enclosure or its wiring. If you're comfortable with basic electronics, check for loose connections within the speaker enclosure or its wiring.

If the crackling persists when you swap the speaker cables to the right channel, it could indicate a problem with the left channel amplifier or sound card output. if the crackling stays with the same speaker even when swapping cables, it's likely a faulty speaker.

Reinstall the audio drivers and if the BIOS is update to date including windows update. Upgrading your system BIOS incorrectly could harm your Acer product. Please proceed with caution. SFG14-73

I'm having the scratchy speaker problem. Good with headphones, bad with laptop speakers. The problem is worst on Zoom, but happens on the music player between audio tracks.

I just sent it to Acer for a warranty repair. As far as I can tell, they completely changed out the motherboard and wiped the memory. They claimed to have fixed the problem, but it persists.

I think that is a problem with Realtek audio driver. I found some advice on the internet to replace the Realtek audio driver with a "High Definition Audio" driver. I'm just not sure how to do that.

I'd appreciate any help. Thank you.

Hi Santhosh2003,

Thanks for the detailed breakdown—sounds like you’ve already ruled out software causes. If the crackling persists only on the left speaker and headphones work fine, it’s likely a hardware issue.

Replacing the speaker is a quick DIY fix—usually a 10-minute job if you're comfortable opening the chassis. These speakers are inexpensive too (around $6). You can find the left speaker for the SFG14-71 on Zandparts, but it’s unclear if it’s identical to the one in your SFG14-73. Acer sometimes reuses components across similar models, but I’d recommend checking the part number printed on your speaker before ordering.

If both speakers come as a set, swapping them together ensures balanced sound and avoids mismatched acoustics. Let me know if you want help identifying the part or finding a teardown guide—happy to assist. 23.KF2N2.002 Acer SPEAKER.LEFT
