If your Dell laptop has a headphones jack but no line-out jack can you still connect a 5.1 surround sound speaker system to it?
You can connect the 5.1 speaker system to the dell laptop as
long as the cable is not an optical or digital cable. Some cables
double analog or digital. These you can use. You should be able to
plug them in if the connector fits. You may not have sound out of
all of your speakers but you can still try. If the plug will fit
then nothing can be hurt. If it does not work you might try getting
an external usb sound card(e.g. soundblaster mp3) I hope that
answers your question.
