Re: buzzing noise from MOBO
Try disconnecting the bleeper. I get the same thing through my onboard sound system. It was annoying enough that I spent $ on a sound card even though the onboard sound had all the features I needed.Comment

Re: buzzing noise from MOBO
Are your speakers close to the tower, or does it have a integraded speaker (to play music and stuff i mean,) if so, it might be that the speakers are turned all the way up, so you are hearing the noise through the sound card on your motherboard.

My Dimension 3000 does that, but it's barely audible. I think it's normal though.Comment

Re: buzzing noise from MOBO
Mouse is usually on +5vsb in standby and on +5v during op by way of a switching IC.
Some may use +5vsb only. (Not sure.)
- USB or PS/2 doesn't matter.
That's done so mouse or hot-keys can wake system.
May be +5vsb or +5v problems in power supply.
Flyback transformer for +5vsb could probably make that noise.Mann-Made Global Warming.

Hello, This is my first post so please forgive me if I miss out some vital info.
I have a problem with my HP1955L monitor from 2005.
The first thing to say is that it is still basically working, ie the picture is fine.
However it makes an electrical buzzing sound. I know all monitors make some some of hum, but this is louder and more of a buzz.
The volume of the noise seems to be dependent on how hard the monitor is working; switched on with a blank screen -> no sound; small dialog (like OSD only) -> minor buzzing; full screen picture -> loud buzzing.

Hi, I got this Woofer,Name TBT, which damaged its Radio module, then was added a Bluetooth module from the market(history from client). Then recently was brought to me with very low sound and heating problem. I changed subwoofer Speaker which had impedance of 1.2 instead of 4ohms rms and the bass ic KA2206B. Sound is back but buzzing and hissing sound present even when muted. How can I get rid of it?03-06-2024, 02:35 PM -
Hi all,
I am working on a sound processor, it tends to overheat so I fitted a fan inside. The fan is connected to the +15V of the PSU via a DC-DC converter based on the LM2596 to reduce the voltage to around 10.5V.
Unfortunately the analogue circuitry is picking up the noise from the fan in two ways:
1. The fan is close to the analogue section, the motor itself gets into the outputs so I'll have to move it somewhere else
2. Even with the fan running outside of the case, there is still some noise which is clearly going back to the processor via power line.... -
Surprisingly enough, this receiver doesn't have the DSP chip issue. The HDMI board does not get hot, and sound over HDMI works fine.
Regardless of the input, the right channel has noise that is clearly noticeable even on average volume level. The only cases when there's no noise is when VCR input is selected (some tracks on the board are damaged, maybe that's why), or if HDMI input is selected but nothing plugged into it. In all other cases, even when no input is connected I still have the noise.
There's some logic behind it. As soon as I select an input I get only left...04-23-2025, 10:09 PM -
Hello
I have since a long time a Philips HTS8010S/01 which has been old but was doing the job.
Since a few days, it starts by making a weird "static" nois when switches on for a few seconds to a minute and then works like a charm.
Noise loudly outputs from the 3 channels, even if no signal is sent by the controler.DVD to the subwoofer/amp unit.
I was thinking of a soldering that was starting to be damaged and that was only doing the job after a few seconds of heating, most probbaly on the power board
Removed each of tyhe boards
