    I'm using Windows 7 and I can't get my external speakers to produce sound. I can plug a headset into the correct socket at the rear of the PC and listen to Youtube OK.

    The external speakers are powered by a cube which is about 15V and a cable connects the speakers to the connection at the rear of the PC, the speakers have a volume control. They are working because I can get feedback noise and are set at full volume

    I think the problem could be a setting in Windows 7, volume slider is OK, it indicates sound is going to the speakers, but there's no sound. I never had this problem with XP, so is there some setting I need to investigate ? Surely if I get sound into a headset I should get sound into speakers. I did say it was a stupid problem !

    My set up works fine, looks to me like you have a bad cable or connecetor.

    Are you using a stereo plug?

    Try going to:

    Control Panel
    Hardware and Sound
    Manage Audio Devices

    See if you have multiple playback devices. You might have the wrong one set as default. I had that exact problem with what sounds like a similar external sound system.

    My spiffy new HP tower is running windows 7 too.

    When I first set it up I plugged my digital input Boston Acoustics BA735 powered speakers with the powered subwoofer in to the digital output jack in the back of the computer and did not hear anything.

    I plugged my analog headphones in the front and the music was there no problem.

    I went to the bottom of the screen and in the task bar I foundthe speaker icon and right clicked on that. A dialog box pops up then that says:

    Open volume mixer
    Playback devices
    Recording devices
    Volume control options

    When you click on the one marked Playback Options you get a new dialog box that shows the play back devices you can use. To switch between the speakers and say the headphones you have to select that icon and make it the default device.

    This advancement really sucks as far as I am concerned. Every time I want to hear something and the wife is watching one of her inane “reality” programs I have to go to the task bar and change it to the headphones. I liked my old computer where I would just plug in the headphones and they worked and when I unplugged them the speakers worked.

    Verify your speakers are good by plugging them into an mp3 player or even your cell phone. Did they work on this machine previously? What brand of speakers are they? Are they from an old computer?

    Mel, that should be the same connection. The speakers go into the same jack that your headset went into.

    The problem with many new audio cards and motherboards with built-in sound card --
    they need to be configured (ports can have multiple functions/usage) with mfg software.

    Had a similar problem. Win7 only recognizes one output at a time unless your sound card has additional drivers for dual output.

    I know on my computer, an XP, I don't have sound unless I click in my control pannel ''Sound and Audio Devices'' then in the volume tab there make sure nothing is muted when you click on the advanced button. Then further down in the volume tab you will see speaker settings. Click on the advanced tab and make sure that you have the right speakers selected. Then in the Sounds Scheme in the sounds tab, make sure that the ''No Sounds'' is selected there. In the Audio tab make sure that the right device is selected. Voice is the same thing, make sure the right device is selected. In Hardwear is the right thing selected in there also.

    Thanks for all the replies, I've made notes. Its a long story but I had the speakers working 2 years ago listening to internet radio stations. I took the PC into the shack for digital activity, Windows 7 drove me crazy, every time I changed bands the audio went back to zero and I could not get whatsit 65HF to work, the download was half missing each time so I brought the PC back into the house, as far as I'm concerned W7 is a PITA.

    I'll have another look, as i'm told, its the same connection for headphones as for the speakers.... crazy !

    If it's the same connection...
    Your audio management software is the issue.
    When you try to run 32 bit apps on a multiple core 64 bit system you can have some strange problems. Windows Seven does a reasonably good job at porting compatibility but it's not perfect....

    I'm looking at having to buy some new versions of apps I am currently running...
    At least they run..................

    The folks at MS use term ( audio) “mixer” without much explanation to us mortals.
    And since Widoze 7 has all kinds of relatively unadvertised changes , pardon me – improvements , I suspect that even with SAME physical output you may have to specify, as already suggested, the actual device you are connecting / mixing to this output.

    It's not a Windows issue. W9GB is correct. It's the hardware in the computer.

    Modern hardware can allow multiple uses for a given jack. But for the longest time, there was only a single output for sound. Some very basic hardware still adheres to that standard.

    Just because you see multiple jacks of the same size from the sound, doesn't mean there are multiple connections for the same output. The "green" jack is the main output. Speakers OR headphones go here, but not both. If you also have a "black" jack, it's likely for the rear speakers in a surround sound setup. If you're just running EasyPal, there is no surround sound data, so the "black" jack will be silent.

    Sometimes the "black" jack is for digital audio out, which is something audiophiles would appreciate, but few others.

    If you have modern, up-to-date hardware in your PC, you can specify a different usage for the "black" jack so that a pair of speakers AND a headset can both be connected at the same time. This is done using the software provided by the manufacturer of that sound hardware, not Microsoft.

    Normally, with no changes by the user, there is only ONE main output.

    You may need to get an updated driver from the manufacturer of your computer / motherboard.

    K9EID can explain audio mixers to you.

    But basically, it's just a means of allowing multiple inputs to the sound channel at the same time, but with a separate level control for each one. That way, one can be louder, or more pronounced than the other.

    Bob Heil uses an outboard mixer to allow him to connect multiple microphones to the same rig. He can also use a mixer to feed the audio from multiple rigs to one pair of speakers.

    The software on your computer basically mimics that electronically.

    And since your computer sound and an outboard mixer both are Stereo, (two channels of audio) and our radio gear is only monaural, (one channel), you can actually double the inputs and outputs to and from a mixer to ham radio gear. The Left can feed one rig, while the Right feeds a different rig, for example. And using the Pan pot, you can decide which rig.

    Yes, sometimes it takes an update to the sound drivers to add the ability to select a usage for a jack.

    And how does this explains why the (stereo) speakers do not work on the SAME jack as (stereo) headphones??? See OP.

    That's right Vaclav ! Why is the connection for the headphones OK but not working for the speakers ?

    I have mentioned the possibility of a mismatch in the plug, stereo or mono. Sometimes these don't interchange. There are adapters.
