    buzzing/hissing laptop (headphones)

    Hello,

    plugged-in laptop buzzes/hissing through headphones, when using heavy 3D applications. Buzzes when switches to headphone jack (when plugged in).

    Unplugged from power supply doesn't buzz. Normal use (browsing, movies..) doesn't buzz.

    Even with sounds to 0, same buzzing is still audible.

      could this be cause by coil whine?

          RCA WHP141 wireless headphones wired up
          by momaka
          OK, this one dates back to 2015! I thought I had posted this, but realized I didn’t when I posted a picture of something else. So here it goes…

          Back in 2015, I bought a pair of RCA WHP141 wireless headphones at Micro Center for $2. I even mentioned it in the best cheap/free scores thread right here. Just forgot to follow up with that.

          As mentioned back then, these are (were) 900 MHz FM wireless headphones. No modern day Blutooth or anything like that. I knew they wouldn’t be great headphones or even that good… but the price was right! So let’s take...

          Klipsch computer subwoofer speakers hissing buzzing. Does this look like bad cap?
          by link626
          Klipsch 4.1 computer speakers hissing.

          Looking at all the caps on the amplifier, they all seem flat, except one maybe.

          Not sure if this is leakage, or factory marker pen.

          Can you tell?

          The speaker system recently developed nonstop hissing noise. after 22 years.

          Is there a special kind of cap I have to buy?
          Low ESR? or general?

          I see these for sale.... Panasonic FC 47uF 50v low ESR radial Capacitors caps 105C New low impedance...

          Windows 10 & Wireless Headphones
          by Logistics
          So I found my wife a pair of Sony MDR-100ABN's, and we were goofing with them yesterday. She has a new HP Sceptre with Windows 10. I don't know 10 at all so my blood pressure goes up trying to navigate the unruly interface.

          I played with lots of settings yesterday, when I was trying to make the headphones connect to the laptop over bluetooth including, the MIC settings since we were playing with the Noice-Cancelling setting on the headphones. I ended up putting the MIC setting back to the Intel default on the laptop, but the output for the headphones.

          Move forward to...

          PowerMac G5 ACBel 614-0303 buzzing
          by dcbw
          The PSU works, but shortly after powering on (either in the G5, or by shorting the power-on pin to ground) it begins buzzing loudly. It also makes the LED lights connected to the same circuit flicker. It's definitely a buzzing, not a high pitched whine.

          The buzzing seems to come from the high voltage side of the board, perhaps from the white relay. Could the relay be bad, or could the 5V supply be bad enough that it's unable to keep the relay on? Any pointers to help isolate the issue? Thanks!

          Samsung P2250W Hissing (Newbie)
          by Lisa Su
          I've been using this monitor for last few years.

          Symptom started by OSD menu popping on and off randomly by itself. So i tried to clean the touch control area with some cloth but it didn't help.

          After 20 minutes monitor started hissing from the back. And then 30-40 seconds later screen started fade off/on like as if i was turning down the brightness that's when i turned it off by power button (hissing stops) and replaced it with spare monitor.

          Today i opened up the monitor, excited to repair my first monitor (or big electronics) hoping it's a bad...
