Chromebook 14 continuous buzzing sound through external speakers when powering on

[verbatim]

I have this consistent buzzing sound when I power on my Chromebook.  Every time I power on, an electrical buzz through my external speakers (plugged in to the headphone outlet) remains until I completely unplug the speakers cable from the Chromebook, and then plug it back in.  Unplugging and plugging the cable back in always stops the noise.

Is there anything I can do to keep my external speakers plugged in without the buzzing noise starting when the Chromebook is powered up?

Hi @verbatim ,

Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue about your Chromebook 14 and the buzzing from the external speakers.

I would be happy to assist if needed. How Do I Find My Model Number or Product Number?

Have you tried to update the drivers once it is connected?

What kind of device is it, model or manufacturer?

Please let me know.

Thanks.

Hey @verbatim , 

What is the manufacture of the Speakers?

1. Have you tried plugging the speakers into a wall outlet by themselves for power? If this is an option.
2. Have you tried them on another computer? Maybe a friends if possible.
3. Do you get the same buzzing from the built in speakers?
4. Have you tried another set of speakers with this notebook, do you get the same buzzing sound?

5. Were there drivers that needed to be installed?

Thanks.

The speakers are made by Creative, Inspire t3000.

1.  Yes, they are powered, so they are always plugged in to a wall outlet and I leave them on always.

2.  Yes, they are normally the speakers for my desktop Windows system.  I've don't have this problem with that PC.

3.  No, I don't hear the same buzzing sound from the Chromebook's built-in speakers.

4.  No, I have not tried another set of speakers yet.  I don't have any others at the moment.

5.  No, there was no software with the speakers when I bought them IIRC.

There is a loud buzzing thump noise made each time I unplug or plug in the speakers to the Chromebook even if it is powered off.  That's always been there.

The buzzing noise appears for about a second whenever I power down the Chromebook, that happens a second or two right after it is powered off.  Also, if I turn the volume control down for the speakers, the buzzing sound volume is lowered too. But if I turn the volume down to where I don't hear the buzzing noise, I can barely hear the sound.  

Update: I noticed after fiddling with the speaker volume control that the buzzing sound goes away now after about 30 seconds.  It didn't just a few days ago.  And it never had the continuous buzzing sound at all when I first bought the chromebook and used these speakers with it periodically.

Thanks.

Hi @verbatim ,

These Desktop speakers are not made for the Notebook. Therefore you will get a buzzing noise.

The adapter can not accommodate the speakers. Best to purchase speakers for the Notebook.

Thanks.

How can I tell which speakers are compatible with the Chromebook 14 and which are not?

Thanks.

Hey @verbatim ,

I would search the Internet for Laptop speakers. They should be made for a Laptop not a PC.

Thanks.
