You mentioned having only ONE output jack on your laptop, if that's the case, it may only provide output from the sound-card (either for headphones or external speakers) If this is the case, then the "Y" cable solution suggested simply will NOT work. My (HP) laptop is designed that way & the solution I came up with was in my pile of old & unsupported peripheral gear I refused to let go of. Let me explain... Back in the days of Windows XP, I purchased a device made by Creative labs called "Sound Blaster Extigy" It connected via USB & among other things, decoded Dolby 5.1, had s/pdif + analog audio outputs (which I used to connect to my sound system) it also sports LINE IN and MIC jacks (which is where it becomes useful to you) Unfortunately, Creative labs is one of those technology companies which puts out innovative products but, rarely keeps up driver support & the included software would not run for me on Win 7. However, the good news I discovered was that my computer WOULD recognize the device itself & give me access to the INPUTS (both mic & line) I just did a quick eBay search & saw that there were a few people selling them relatively cheap (approx $20 + shipping) which is a deal considering that the original retail price for it was about $150 "back in the day" Note: there are also a couple of Amazon "marketplace" sellers who have them listed for sale at more than twice that amount. I hope this info helps you sort out this issue
