Product Reviews
Startech.com USB Stereo Audio Adapter External Sound Card is rated 4.6 out of 5 by 5.
Rated 5 out of 5 by from Best sub-$100 home theater/stereo investment ever I run a tri-amp system that predominantly plays all channel stereo from my .flac library. I am most definitely an audiophile and there is certainly a SQ improvement using this device. I have a 3.5mm spdif to optical audio hooked straight to amp 1 as opposed to laptop media port (? Is that what it's called) to HDMI to TV then optical out to amp 1. I recommend setting the main volume to 85% player at 100% then adjust amps from there. Last night I set up Dolby Atmos for headphones free trial plugin, enabled 7.1 virtual surround and hooked my velodyne cans to this device. I was blown away with the AC3-encoded Valerian and the city of 1000 planets swarming around the headphones. Top notch product, startech. Hurry up and make an android app/plugin so I can enjoy my .flacs on my LG g5 with neutron! Also, send me some devices to review on my blog. You guys rock!

Rated 5 out of 5 by from No need to replace your sound card It has become a hassle to replace any type of card inside my computers. I used to do it all the time, back in the day when computers were simple. But now, what kind of buss to I have, what type of memory - I no longer have the knowledge to confidently upgrade or change out components. I'll bet there are a lot of folks in the same situation. The sound on my favorite old computer got so bad I almost got rid of it. I couldn't even understand the spoken word. But I decide to try the Startech External Sound Card first and it worked flawlessly. Simply plugged it in and ran the software - Wa La I was listening to great music once again. I have bought other Startech products and they too proved to be good products, so I doubt I will have any trouble with this one.

Rated 5 out of 5 by from Works as you would expect I purchased this adapter a month or so ago with the primary goal of getting an optical output out of my Windows 10 PC. It works like a charm. Obviously, I was looking to get high quality output. This too was delivered.

Rated 3 out of 5 by from Beware Windows 10 users This seems like a great product but I get an error when I try to install on my windows 10 laptop. Because I cannot install the driver, I have to plug in the device then plug headphones into it in order to hear any sound. Wish they would update for windows 10.

Rated 5 out of 5 by from Great Sound Again I had bought two new laptops running Windows 10 both, however, only had a single audio socket for a headset and not proper stereo line inputs. As a result when trying to record my old LP records I would get prominent tick, tick, tick sounds with the music quietly underneath it. I eventually found and ordered a StarTech Stereo Audio USB External Sound Card with SPDIF Digital Audio. After a bit of changing inputs and setting the input as a USB microphone and output as the laptop's normal speakers the sound is perfect again. The search was not easy as I didn't really know what to look for - many USB adapters are not stereo, and this is. I got mine from Span.com as I'm in the UK.
