Aspire A515-45 beep when going on/off battery power

When I'm doing something computationally demanding (e.g. photo editing) the laptop will sometimes switch to battery and then immediately back to AC power, within a second or so. Each switch is accompanied by a hardware beep. The battery charges and works fine, BTW. I'm not in BIOS now (obviously since I'm writing this online!) but I've looked before and haven't found a power beep toggle.

Any idea how to disable this annoying beep?

Thanks.

    @lenphilpot Try to mute this one. The beep charging sound is from this one. Don't worry, it doesn't affect the main audio.

    @lenphilpot you can try to find an app that permanently mutes the Realtek HD Audio app. Using volume mixer will help but will revert to unmute after the restart.

    If the battery is properly charged and fully functional, regardless of your workload "switching" to the power adapter indicates a city utility issue possibly brownouts by the electricity provider? Alternatively it could be a bad power cable contact, check your power cable and plugs from wall socket to the adapter/charger and the pin plug/port laptop, jiggle the plugs a bit to see if that causes the power to battery switching.

    The system beep during switching is a standard Acer hardware audio function by the motherboard to inform you of brownouts or adapter issues, if you disable Realtek in Start Task Manager that beep will stop.

    First off, my apologies for silence on this topic. Apparently email notifications didn't work... :-\

    At any rate, I've already ruled out bad power, power supply issues, etc. The beeps happen only when I'm doing something processor-intensive during photo / image processing (raw conversion, image editing, etc.). It goes off and immediately back on AC power -- I can see it in the Windows event log.

    I don't want to disable Windows audio since this is my daily driver. Beside, the beep isn't coming through Windows audio, but rather straight from the system board. This appears to be a hardware beep. Are you saying it's also controlled by the Windows Realtek driver?

    Thanks.

    Hi @lenphilpot

    Partly, when Realtek is enabled in startup (Task Mngr.) the beep will play when the power adapter plug is removed, when disabled no beep and all audio functions will work normally. RTK driver is finicky, also when changing the audio frequency/channel will stop the beep I found out.

    @AnhEZ28 That did the trick - Thanks! No more beeps and still have audio. Although (I've not tried it yet) I suspect I'll need to turn it back up when I'm mobile and using the internal laptop audio.

    Thanks again.
