Altec-Lansing Speakers and Subwoofer not working on new Dell with WIN7

[mefrank17]

I have an Altec-Lansing speakers ACS40 and subwoofer ACS250 system that came with a Gateway 2000 PC that I purchased in 1995. And has worked with every computer I'ved used since, the last having XP Home Edition.
However they do not seem to work with my new Dell with WIN7. Any advice?

Exactly is the 20 year old Altec Lansing speaker system? Back then many PC sound systems were different.

Are these speakers analog with built in power amplifier? (needed for current PC speaker systems). Or are they non powered as many older sound cards had power amplification on the sound card. And then there were the Gateway PC's that used digital speaker systems (and that digital type is not compatible with current PC digital connections).

What is the Dell PC Model number (such as Inspiron 310, etc). One with a 32 bit OS would suggest an older Dell as most (all that I've seen) new PC's come with 64 bit OS.

thanks for the reply. The PC in Inspiron 3847 and it is 64 bit and the speakers do have a built in power amplifier.

To verify if its something in the PC or the speakers, connect a headset to the GREEN speaker jack on the rear and see if you get audio.

An afterthought. Make sure the "Speakers" are set as the default audio playback device.
