Buzzing sound in my speakers when I switch to the phono stage
I get buzzing sound in my speakers when I switch to the phono stage on
my receiver. I noticed that it is related to the dimmer switch
controlling the track lighting in my living room. When I turn off the
lights buzzing sound disappears. Right now I plugged my turntable into
the contact furthest away from the dimmer, it helps but the buzzing
sound is still there. Is there a piece of equipment that will eliminate
Please advise. Thank you.

Re: buzzing sound in my speakers when I switch to the...
It is a grounding issue with the turntable most likely. Some turntables came with a ground wire that you attached to the receiver. You can also try a power strip that has a line filter incorporated to get rid of the hum. Check the local stereo shoppe to see if they carry them. You may also want to replace the audio cable that connects the turntable to the amp with a good quality shielded cable. If it has bad shielding it will pick up electrical interference and even radio interference as well. Turntable inputs on receivers have a preamp built in and the gain for each type of pickup is different. The pickup is either ceramic or magnetic and if I remember correctly, the ceramic pickup needed more gain than the magnetic one. The preamp will definitely make a ground hum a lot more audible.

if your computer came with a motherboard disc the sound drivers could be on it click start control panel administrive tools computer management device manager scroll to sound,video and game controllers you might see a yellow question mark? Right click to reinstall drivers or uninstall click start control panel sounds and audio,volume,advanced,speakers make sure you have selected the (((appropriate speakers))) also audio you will find 3 drop down lists make sure you have the correct settingsthere also click start control panel sounds and audio devices you can adjust the volume there also select speaker volume you can change your settings there you can also tick in the box place icon in taskbar if his does not fix the problem
have you tried this control panel sounds and audio,volume,advanced,speakers select the appropriate speakers from the drop down list or navigate to the device manager scroll to system devices + to expand,system speaker right click properties then select use this device (enable) also you might check the speakers plug/outlet is usually at the back of the computer you will have to open up the computer to check the lead attached to the rear of the input plug make sure the connection is good try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the sound card and the CPU central processing unit dust causes static to build up in a computer make sure you have an earth ******** before touching any parts inside your computer hope this helps
Right-Click on My Computer, select Properties > Hardware > Device Manager
Once in there, is anything in the list flagged? If not, then it's definitely possible that your on-board sound went bad. Luckily you can install a PCI card that will perform the same purpose for little money. A decent option would be:
A general case might be to take the stereo headphone output of the laptop and feed it a set of left and right line level (not microphone level) inputs to the soundboard. Radio Shack sells a cable that has a typical mini stereo headphone plug on one end and a pair of RCA Phono plugs on the other end. If the soundboard does not have phono jack inputs you will need some type of adapter plug on the ends of the cable phono plugs to match the soundboard's connector.
You then experiment with the laptop's volume control setting (start low) and the soundboard's input level control to get undistorted sound with minimum noise and hum. If you can not get rid of the hum, you probably need to add a ground loop isolation box (also available from Radio Shack, I believe) to reduce or eliminate the hum.
Make sure all wire are tight and that you have power to the speakers.
Turn the sound all the way up and put the speakers up to your ear, if you hear a buzzing that means your speakers are okay and you need to configure your computer.
If you have to configure them with your computer plug them into your comp and go Start>Control Panel>Hardware and Sound>Sound then select your speakers as default device and you should be good to go, if you have any further questions just comment back and i would be happy to further assist you,
Hope this helps
Where are these speakers hooked up to, computer ??
If so, open device manager (Click start - run - type devmgmt.msc) - expand sound video and game controllers - right click on all the submenus and uninstall them one by one(Which gives you uninstall option) - close the window.
Restart PC and notice results.
Make sure in the volume mixer that it is using the right sound device. You most likely have it set to the wrong device output. When you plugged in the headphones in kinda automatically switches, but to use the speakers again you have to do it manually. Just hook up a cheap av receiver to your computer and use this headphone input instead. a 100$ 5.1 av receiver beats any pc speaker system.
The easiest solution maybe to uninstall the app that caused the problem if possible. if not, goto control panel and click on sounds and audio devices, there are sttings there related to the hardware and output
IF you have xp go to control panel/sound,speech and audio. You will see a drop down choice that says change speaker settings. Click on this. Then under the tab that says speaker settings hit advanced. Then select the sound scheme that says monitor with stereo speakers and apply this. Assuming you still have a functioning sound driver this should return it to the monitor speakers. Hope this helps.
Go into global settings, choose the MIDI settings and make sure the very first box is checked. I lost my sound and had a similar problem and just did some troubleshooting and once I clicked that box, my sound returned. Hope this helps.
