Front left speaker stopped working. I use the system with my computer (full volume on computer), and usually half volume on the speaker. I've had the speaker for a few months now. I looked the wiring to the speaker and it seemed fine, disconnected and reconnected it a few times and it still doesn't work. I even connected the speaker with problems to the front right speaker cable and it works fine then, but stops working once i reconnect it to the front/left wire again. what is wrong with it? any suggestions?

I don't know for certain but, this is usually a sign of the overload circuit in operation. Speakers are not designed to be used on full volume constantly. Next time this happens try and turn them off for a couple of minutes, when you turn them on again try with the volume lower than when you turned them off. If you are regularly using them at full volume, then maybe it is time to invest in a more powerful set. Buy them by their RMS power output, NOT by their PMPO (peak mean power output) this is already an inflated figure and is usually about 4 times the real power output. I hope this helps.

if you are having problems with your sound
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
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 settings there
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
hope this helps

try reducing the output volume from the pc, maybe to about half or even a quarter of full volume. now increase the volume on speakers.

• this is probably a connection problem so check the connections and if neccasary replace the cable connecting them with the computer.
• also chechk to make sure its not muted internally (muted on the computer itself)

On the right stick, there are two metal pieces at the bottom of the stick. The right one is + for volume up, and the left is - for volume down.

Press the + one a few times with your finger as they are touch activated. Be careful though, as it can get loud very quickly. Play some music and set the computer volume to about half way. Then press the + speaker on the right hand side until you are happy with the volume.

Hope this helps,

This isn't usually in the satellite speakers. The amplifier is usually in the sub and these have a bad habbit of blowing/burning up. Return or replace. Pretty common in this model.

Look into your computer audio setup, usually a icon in the lower right. they have controls for volume, some have different areas such as oper sounds, outdorrs, etc. Maybe these are turned down or muted...Also plug a head set into the CD or DVD rom port in the front if yu have and see if the volume is good. Possible bad audio card. Also try different speakers. Small speakers sell for $20.00 or less.

I think I had a similar problem. My speakers were brand new and after a while I lost my front left and rear left speaker. I'm not sure about you guys but after fiddling around with the settings it worked after I changed the "S/PDIFoutput sample rate" from 48 to 96 khz. I have no clue what I did, but it worked for me. I am running logitech something or rather speakers with VIA HD audio deck drivers

The first things I would check would be the volume control within your operating system. If I assume you have Windows XP, you would go to Start-->All Program-->Accessories-->Entertainment and click "Volume Control". Make sure all of the sliders are at least 1/2 way up. You might also want to check to make sure the cable from the speakers to the computer is plugged into the proper jack (usually the green one), as sometimes computers have jacks for rear speakers, which might make them sound quieter.

Guys,

In case my nickname does not show, this is treefarmer. I had the same problem and decided to fix it myself over this Christmas. I was successful, and here is what I found.

In my case, the problem lies with the volume control chip ( it has a voltage controlled amplifier, or VCA in it) on the main amplifier board. The voltage which controls the volume for all channels comes from the right front speaker. There is an issue with the I.C., in that it has some abnormal loading (leakage) of the volume control signal at the I.C. pin. You need about 5.2 volts for full volume output, and on my system, I can only get about 1 volt. You can find the IC data sheet (Mitsubishi M51132L) here:

datasheet.html">http://www.datasheetarchive.com/M51132L-datasheet.html

The parts inside the enclosure get quite hot under normal operation, and I would not be surprised if this I.C. has an issue with degradation under high temperature. Regardless of the problem, I managed to get the volume back with one simple fix.

If you can open up the right front speaker, place a 10 kohm resistor in parallel with R1, which should have three orange stripes, and one gold stripe. This fixed mine, but this might only be temporary, depending on how much worse the volume control I.C. becomes.

I did check out the power supply, including transformers and everything else, and they all look fine. It would surprise me if the transformer failed as has been posted in other forums. They should be able to survive higher temperatures than the other electronic components in the box, especially when most of them are consumer grade parts with a max temperature of 70 C. One thing of note is that turning off the right front speaker pretty much shuts off most of the quiescent current draw of the amplifier board. I found that with only the sub cabinet switch on, nothing gets warm. You won't see significant warming of the interior components until you turn on the right front speaker. However, then the inside of the sub enclosure gets pretty hot (too hot in my opinion) just sitting there with all the speakers powered up.

I would recommend at least turning off the Right Front speaker when the computer is powered down. More often if you are not listening to anything. I don't think you need to shut off the sub enclosure to keep things cool, but turning off everything ensures that the amp is not sitting there cooking itself. And, unless Altec has changed the design, I would bet new systems will fail in the same manner.

For what that's worth. Hopefully somebody will find this helpful
