Summary: This is a usb input audio wave device for pc or mac. I been using one already for years for my notebook. When I got a 2nd computer for home, had to get a 2nd one to leave at home for use. Very good if speakers on desktop or laptop are lacking.
Summary: The Soundwave was easy to install and worked perfectly. I didn't need anything with lots of features, just something that would do the basics when my built-in sound on my motherboard went out. I bought a pci sound card first, but could never get it configured so that it worked. I'm glad I found the Soundwave and it was reasonably priced.
Summary: When I put this USB Siig Sound device in my net book it produced a lot of static. Even worse, when I plugged my computer into AC, it began to hum. Took it back to Walmart the next day. They are very good about refunding bad products.
Summary: Based on multiple reviews, on this an other external sound cards, I was concerned about getting true 7.1 surround sound through the optical digital output since optical outputs are limited to 2 channels unless the information is compressed through Dolby Compression in the card. I was looking for a way to boost the sounds from my computer so I could watch movies while exercising, with sufficient sound to drown out the equipment sounds so I could hear dialog.
