Digital BA735:
"Digital output sound card; Digital output must be a 3.5mm mini-din digital out; Note: (1) This speaker set will not work with analog sound cards. This speaker set will work with digital output sound cards only (like the Creative Labs Sound Blaster Live 5.1)."
There are conflicting reports on these speakers, some say they only work with a digital input, others say there is an analog (line level or headphone type) input. Plus there's a version that is for Gateway PCs only.
You are going to have to go to your speakers' instruction manual or get to Boston Acoustics on this, whether they work or not will be up to the speakers' design and requirements for software drivers (although if they have an analog input they should not need to use software drivers).
yello: self powered speakers are usually plugged into the headphone (audio out) port...
