Try swapping the speakers around if the problem still persists either the speaker is faulty or
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
or you might have to clean the dust from your computer dust causes static which causes your computer to overheat and all sorts of problems
be sure to wear an anti static earth strap before touching anything inside your computer hope this helps

If you live within the United States, you may be able to go to BestBuy or Radio Shack to get a similar power cord that will power your speaker system. Just try to get an idea of the shape of the connector.

My speaker set up boston acoustics ba7500 will'nt


The Guys at Boston Acoustics helped me get my speakers to work. The Boston BA7500 speakers are coaxial digital speakers so you need a digital output on your sound card. Analog will NOT work. My new HP Pavilion has a Realtek sound card with a digitial RCA plug output. I had to go to Amazon and get a male RCA to 1/8" Stereo Mini Female adapter plug. I just pluged it in and configured my sound card to 16 bit 48 khz output to the RCA output and everything works great. The speakers sound better then ever, great for 10 year old speakers! They sound better then anything I have seen avalable today. The guys at Boston were the only guys that helped with getting this to work! Thanks again to them and Amazon has every type of adapter plug you may need. Good luck.

Trouble with rear speakers


This may be a software issue. If you only had two speakers before, the software will not use the rear speakers.
Go to Control Panel. Click on "Sound and Audio Devices". Under the Volume Tab, at the bottom, you will see a picture roughly representing the type of speakers.
Click on the Advanced button.
Click on the arrow in the pick box, and choose Surround Speakrs or the 5.1 Speakers.
Click Okay. Try the speakers again.

Boston Acoustics BA7500... Problem


Try installing an old creative driver for digital audio but use system restore to take a backup of your settings first. Also, you may have to update the bios and unselect the AUTO mode for sound.

Boston Acoustics Computer Speakers no sound


This speaker system requires a digital audio input, which most older systems don't have. The sound card that was built into your Gateway can put out either a digital or analog signal depending on how you have it set. Chances are your new sound card might be able to output in digital mode as well, but you may have to turn it on manually. Try double-clicking your volume icon in your system tray, then click the "advanced" button at the bottom left. This should bring up a window that lets you adjust the treble and bass, but it should also give you an "other options" area that lets you turn on digital output. If your new card supports digital output, the option should be there. If the card does not support it, you will have to use a different card. I hope this helps.
