    I have a G9-793 and was experiencing the same issues as all of you have been reporting. The buzzing started up in late December and occurred when the computer was under a high load (Nvidia Iray rendering). I thought I would have to take it in for service, but as of the latest Nvidia driver update (23.21.13.9065) that I installed two days ago, the sound does not return even if I render the same scenes that would cause it prior to the most recent update.

    Just wanted to put that info out there. I did not update BIOS or any audio drivers. The only update was the display driver. YMMV.

    I also have the latest drivers, bios etc, still buzzing. It's a heat issue for me. Once the GPU or even the HDD (51*C) get hot enough for long enough, it will start buzzing.

    UNLESS i run fans at 100% which is not ideal at all...

    Called Acer predator support, spoke with a technician, explained the issue I am having with a speaker noise. He said I need to send in my laptop for repair to Texas. I really do not want to do that. I would rather take it apart and disconnect the speakers. Does anyone have a video of how to take it apart and disconnect the speakers?

    Still haven't sent mine in yet, waiting for end of my exams... It does suck to send the thing you mainly work on for repairs for 1-2 weeks.... I think the problem is deeper than just the speaker making noise tho. It's also getting worse now. The buzzing will happen even if not in high load sometimes which is really annoying.

    Mine started to crackle again, too, after being stable for two days after the latest Nvidia display driver update. I need to finish a project first before contacting Acer as this is my primary work machine as well, and I am not looking forward to the hit this will make in my production work flow.

    I solved my crackling sound issue. Basically, I took the back cover off and disconnected a connector next to the battery. Speakers still work, and the annoying noise is gone. I even took a screenshot of the connector which I disconnected specifically for this forum, but I get a stupid message saying "You have to be around for a little while longer before you can post links" Look for the video on youtube called "Acer Predator 15 (G9-593, GTX 1070) - disassembly and upgrade options" which will explain to you how to take apart your laptop. Once you take the cover off, there is a small 4 pin connector next to the battery (not the big one!) with white, red, and black wires which I disconnected which solved the crackling noise problem.

    Again, I don't think disconnecting will solve the underlying issue

    In addition, it would be nice to know exactly what is being unplugged.

    Personally I think it's some motherboard component getting too hot, maybe some voltage regulator or something. Maybe the audio chip itself. Simply disconnecting the speakers shouldn't be classified as a solution... Usually the right side of the laptop gets hot when this starts as far as I observed, might be wrong.

    You'll notice orudie said "Speakers still work...", meaning they're not even unplugging the speakers...just some other random component. :|  They didn't say what that component was, which I find problematic.

    This occurs for me as well.

    This is the connector I disconnected which I mentioned earlier and the noise is gone. I thought this was the speakers connection, but it is something else. I am not sure what it is, but ever since there are no issues and I do some heavy gaming every night and no more noise. The battery is charging, and everything works as it should. I will keep watching this forum thread, and maybe someone can identify what it is. I am just so glad not to hear the stupid buzzing noise every time I turn on a game.

    Very strange, they look like the speaker connections, but you say they still work? Wtf?

    This is the speaker connector, I don't understand how the speakers still work after being disconnected.
    Always post the following characterisitcs of the device:
    -Model number
    -Part number(not required, but helpful)
    -CPU
    -GPU
    -Operating system

    Helios 300 and Nitro 5 users DO NOT update the BIOS to version 1.22 if you don't want the keyboard's backlight to turn off after 30 seconds even when the device is plugged in.

    I guess it could be the subwoofer only.

    Are you sure any sounds aren't coming from the subwoofer, orudie?

    Still not a fix for the underlying problem though...
