Let verify first to narrow down to where the problem can be. First, make sure the MUTE function is not activated, then check the on screen sound set up menu to make sure the speakers are not set to OFF. If the setting is OK, then attach the powered PC speakers to the Audio Line out RCA jacks (Red and White) to see if you can get the sound there, if you do, then the problem can be in the power amp circuits, if you do not get the sound at RCA jacks, then the problem can be in the sound processor circuit. Please post back what you find.

When I plug in my marantz TT-42 turntable to my Yamaha R-S300 receiver's phono input, I get a muddy and loud sound. I've tested the turntable with direct input to Bose speakers and it works fine.


If the turntable produces good sound with a line level input on another system, you have the turntable with the pre amp built in. That is why the sound is loud and distorted.

How to hook up speakers? Sound sounds muffled


You DON'T connect speakers to this... this is NOT a powered mixer... you MUST use external amplifier !!!! You use bvalanced (TRS) cables to a suitable power amplifier which connects to speakers. Some Behringer mixers such as the PMP5000 have built in amplifiers to drive speakers... yours does not.

I have a acer with the acer crystal eye webcam built in it. do it have a microphone with it. if so how do I get it to work?


The Acer with crystal eye webcam will also have a built-in microphone. The webcam is in the center at the top of the screen. The built-in microphone is typically half-way between the edge of the screen and the webcam. It is a little opening with a microphone logo beside it. You can test both audio input with the built-in microphone and the audio output with the built-in speakers by doing the following....
1. click start > Control Panel > Sounds and Audio Devices
2. in the Sounds and Audio Devices Properties click the Voice tab, then click the Test hardware button
3. in the Sound Hardware Test Wizard window click the Next button, if required, click unblock...
4. speak into microphone to do the Microphone Test. Recording meter will show movement if it works.
5. click Next button to do the Speaker Test. Microphone input is now output on the speakers.
6. click Next button when finished doing the readings and click Finish to close the wizard.

Trying to connect BA735 speakers to a MacBook? No sound? Are they compatible?


Those speakers were originally supplied with Gateway computer system that had sound cards with digital outputs. While some versions had analog and digital sound inputs, most often the speakers had digital input only. The on-board sound in the eMachines is analog output only, so the speakers are most likely not compatible with your computer. If you want to use those speakers, you will need to locate a PCI sound card with digital output.

It's a matter of the output from the computer's sound card (built-in) being incompatible with the speaker input. The card is sending out analog sound wile the speakers are expecting digital input. Downloading a driver won't help because that doesn't fix the root problem. You need to get speakers designed for analog input, or a sound card with digital output. As it stands now, your computer just can't use those speakers.

Since your using a MacBook there is no option for this Pci Digital Sound Card.

No sound, other monitors have a input jack for sound but not this one.


Some monitors have built-in speakers and others do not have them.
In this case you need to purchase separate external speakers to connect into your computer. If your computer has audio output for surround sound, then you can buy 5.1 surround sound speakers. These will have 2 front speakers, 2 back speakers, a center speaker and a sub-woofer speaker..

Does this thing even have speakers..cant get any sound


It definitely has built in speakers:

Built in Speakers 2 x 3W speakers

It also has a headphone out jack. If you can't get sound, check and see if the headphone jack works. Does the volume control work? If they do your problem is with the speakers. They may be blown or just disconnected.

If you can't get sound through the headphone jack and you do have volume control but no sound, it probably a problem with the mainboard. It may need to be replaced.

Not really worth fixing in my opinion. I'd Just get some external speakers and connect them that way. Of course, if you are relying on a cable input, thats a bit harder and you would need some tuner or a DVD/VCR player with a tuner that has the standard RCA red and white audio output.

Starlogic monitor - no sound


Did you plug in a sound input into your monitor? It will be a separate wire from the video input.

If it has a 3.5 mm stereo input jack then it probably has speakers, and you should connect that jack to the green headphone jack on your PC. If it has no input jack then it probably has no speakers.

Of course, the sound input might be included in the VGA cable, in which case that would divide near the PC with a green jack-plug on the end. Again, plug that into the green socket on your PC.

Installed new monitor, lost my sound


If your previous monitor had built in speakers and your new monitor does not you are going to have to purchase new speakers. If your new lcd monitor has an audio input you can purcahse a sterio mini jack cable for under $10 at any store that sells computer stuff (circuit city, best buy, walmart, target, etc). Simply plug one end into your monitor and the other end into your computers audio output jack (usually color coded green). Now of course if that monitor does not have built in speakers your only option is to purcahse a set of speakers for the computer. These usually start at around $15.
