Rated 5 out of 5 by from Win 10 keeps messing up this device I have used this device since Feb 2016. It works great when the drivers are correct. However Microsoft updates keep messing up the drivers and it's next to impossible to restore the driver settings. Until a better driver install is available, I suggest avoiding this product or be ready to waste hours upon hours installing drivers.

Rated 5 out of 5 by from powerful and simple I broke my headphone jack on my laptop and this product fixed all my problems quickly with no effort other than to plug it in and change a couple of settings in the sound options. Very happy customer right here!

Rated 5 out of 5 by from Better than any internal audio card I have had one of these for over a year now. Best thing about this card is the ability to have more than one input working at the same time. Windows DRM since Vista has disabled the ability to have Line in and Microphone working at the same time. Since I have two computers, one connected to line in on this and a microphone for talking to friends it does exactly what I need. I have purchased several audio cards and spent hundreds on some that couldn't perform as well as this one.

Rated 5 out of 5 by from Average product with hidden limitations I purchased this unit because I use a Small Form Factor PC with limited upgrade options. On the photos I could see it has a lot of connections. I wasn't interested in the 7.1 features, but more for recording purposes, especially the optical input. The C-Media Audio chip in this device is quite basic, limited to 16 Bit and 48 KHz. So it won't do 24 Bit or 96 KHz or any of that. The specifications and manual mention that the S/PDIF optical input is only pass-through, yet it shows up as an input in Windows 10 and you can record just fine with software such as Audacity. The specifications mention dual microphone inputs. Yes there are 2 ports, and you would assume that you can connect two microphones, but this is not the case. Windows audio properties show only a single microphone input. The way this USB audio device is setup is that the left mic port is for the left channel, and the right port for the right channel. Rather than have a single mic port that does Stereo. Very strange and means if you have standard Stereo Mic you need to get a Y-cable. Finally the device has optical-in, line-in and mic-in. On a standard sound card you can use all the inputs simultaneously. For example receiving music from the line-in, while doing a voice over through the microphone. But this device only supports on of these at a time! So it's either optical in, either line-in or either mic in. But you cannot use two or three inputs at the same time. I'm amazed at this limitation and that this is not mentioned. The driver seems to be quite old and mixer has just two sliders for volume and CD, which makes no sense. There are no sliders for the other ports. The software and driver doesn't seem to add much compared to the built-in functions that Windows 10 provides. On the positive side the build quality seems solid. The buttons on the unit as handy, but most keyboard have the same volume and mute button. The mic mute button though can be very useful. The power LED blinks all the time which is a bit strange. All in all the product didn't meet my expectations, especially that you can only use one input source at a time and that this wasn't mentioned anywhere.

Rated 5 out of 5 by from Wow finally plug & Play Bought this fix a Realtech audio problem that wasted MANY hours of my time I plugged this in and it M$ Win 7 picked it up immediately and the volume nightmarish issues are gone the lack of vocal clarity is gone For 20 years as a tech been happily using Startech products but this was a sweet easy and could not be faster install. For anyone wanting an optical out - stop right here this is the one. Outstanding

Rated 5 out of 5 by from Not working at all I got this as a Christmas gift from my parents last year. I'm finally getting around to using it and it is not sending a signal to my receiver. I can see the blue light blinking on top of the box but there is no red light coming from the S/PDIF.

Rated 5 out of 5 by from Raspberry Pi My mate bought this for his windows system and I had my raspberry pi with me... Plugged it in and it worked without installing additional drivers... It doesn't say in the manual anything about Raspbian OS so thought I would let everyone know it worked...

Rated 5 out of 5 by from buzzing sound and only stereo is working I bought this external card to be able to use my Logitech Digital Audio controller for my 5.1 speakers and my new Dell Optiplex 7060, which apparently offers no internal sound card option with a digital audio connection. No problem, except that I get an annoying buzzing sound at any volume, and it's only working in stereo mode and pretty low quality from what I can tell, Something isn't right, but I can't figure out what to do to fix it.

Rated 5 out of 5 by from Really good upgrade Bought this card to take advantage of my Logitech Z506 5.1 Surround audio, however the drivers have not been necessary in my case since windows handles this device so far without problems

Rated 5 out of 5 by from Works as promised! This is an excellent audio addition with a 5.1 or 7.1 speaker set. I can work much longer when listening to music through this unit.

Rated 5 out of 5 by from 5.1 sound Rocks I had purchased a new computer but it didn't have the output for 5.1 for my speakers so I purchased this nifty item. The disk that came with it didn't have the drivers I needed so I downloaded the software for it and I got my 5.1 sound back. I am a happy camper rock'in out to my tunes.

Rated 5 out of 5 by from Easy install, no added software Was installing this on a Windows 2008 Server, and was concerned about having to install extra software that might cause some issues with the software we are currently using. Thankfully, the driver was already in Windows, so no added software, which meant that no ill effect to the system. Just, now we have sound. Very nice.

Rated 5 out of 5 by from Bought for the wrong reason, but supprised. I have an old Klipsh computer sound speaker system (whose sub is also an amp.) that was paired to a (at that time) high end gaming computer's sound card. Computer long gone now. Found a convoluted way to hook up these speakers to a retired HK receiver using only the pre-amp functions as the amp portion was dead. HK amp fully died. Needed solution to use speakers system. PS: this is still a very good sounding system for my bedroom. Found your 7.1 USB Audio Adaptor. Hoped I could just use it without the computer. No go. Disappointed. Used my notebook. Worked, sort of. Only 2.1 and no headphones. Hmmm. Drivers down loaded automatically were generic. Try the disc, not compatable with Win 10. Went to you web site, got Win 8/10 drivers. WOW. Impressed for such an inexpensive item. Everything works,. Controls the amount of speakers to use and can even use other audio players via the input. Still checking it out, but happy now. Can't run it without the notebook, but for the price, that's OK.

Rated 5 out of 5 by from Just what I needed - Line In I have my own preamp and needed something to digitize line-level signal. Startech does it fairly well, with excellent low-frequency response - which is great for my application.

Rated 5 out of 5 by from Perfect (once I got new drivers online) I just this box and, so far, it's been working great. I needed to download new drivers off of the Startech website to make it work with Windows 10, but once I did, no problems. I have a Dell laptop and I got some 5.1 speakers secondhand so I needed a USB solution to give me 5.1. This was exactly what I needed. The sound quality seems fine, although the speakers I'm using are not great. Works nice with games, Netflix. Very pleased.

Rated 5 out of 5 by from Very happily surprised! Sound is on par with the famous name PCIe card, best of all I don't have to uninstall drivers/software then reinstall every few boots like I did with that expensive card. Sound is def better than the OEM/Intel/Realtek offerings--not to mention it's a snap moving from 1pc to another (try that with an internal card)...I downloaded the StarTech zip file rather than the enclosed CD, installation was a breeze, the program has plenty of tweaks to keep me busy. i should have bought this usb StarTech years ago!

Rated 5 out of 5 by from Fantastic Customer Support!! I had a connection issue. I contacted customer support and first chatted with "Chris". I am not computer savvy like I'd like to be, so he took over my computer and installed the software that was necessary. That didn't completely solve my problem, so I re-contacted them and got connected to "Justin". He troubleshooted my problem and figured out my issue was a setting on my computer. I am now enjoying fantastic sound form my laptop. This sound card is a MUST HAVE if you enjoy music!!

Rated 5 out of 5 by from When you get it working it's great! I got this to reuse a 7.1 surround sound system that was collecting dust in my loft. I plugged it in on my Win 10 machine (Version 1909) and it seemed to auto install. Problem is it would only output as "headphones" no options to output in any other way. I then installed the startech drivers from the website, still nothing. After half an hour of troubleshooting I contacted support, long story short you need to install the drivers from the Startech website which will install the app "Cmedia Xear Audio Centre", open the app, right click on the "Headphone" icon, select the second option "headphone settings" then in the top right select the drop down box that says "Headphone" then you can select "speaker" or "SPDIF Out" . once you select "speaker" the "headphone" icon will grey out and "Speakers" will be selected. You can then output in 5.1, 7.1 etc! No mention of this un-intuitive "feature" in the manual but support were great!
