Please wait . . . 7.1 USB Audio Adapter External Sound Card with SPDIF Optical Digital Audio is rated 4.5 out of 5 by 2.
Rated 5 out of 5 by from Sonic improvement over built-in computer soundcard I bought the StarTech external soundcard to overcome the shortcomings of the inbuilt Dell soundcard in my PC in respect of distortion and extraneous PC generated noise. I use it for stereo recording and playing with external audio equipment but have not used the surround sound features. It was plug and play compatible with my Windows 10 system and also with Ubuntu Linux on another computer. I did note that the default signal routing to headphone or front loudspeaker was operating system dependent, with Linux it was transparent and easy, but with Windows 10 it was the usual fight against the system and I always have to plug the phones in the front LS output. The signals out are of course all low level and not for direct loudspeker drive but more than adequate for phones. The audio quality is really excellent- this judgement from an analogue audiophile. I usually avoid digital sources but I must say that the transparency of the sound and superb fidelity is a relevation. Direct comparison of computer output versus StarTech leaves you in absolutely no doubt that this is vastly superior, the PC output leaves you disatisfied wile StarTech has your foot tapping. I listen to serious classical music and Jazz but also do speech recordings to send to isolated friends. I have not used the SPDIF interface as yet. I think it only acts as an input, at least as far as Windows 10 is concerned but there were indications that it may output from a Linux source however I was not able to test that out. I was a little puzzled by reference to the TOSLINK input/ output as being "feedthrough"- this suggests that it can input but act as a link in a daisychain. This feature requires greater clarification in the instructions. In summary, if you want great headphone audio quality (you may need to use Front Speaker rather than phones- operating system dependent) this is an excellent product. The record input can be via line or microphone (using only the right socket gives default mono), if you have a stereo mike with a stereo jack you will require an adaptor to two single pole jacks at the input. The controls interface directly with the PC and set output volume and mute. If you grapple with surround sound on your PC interface I see no reason why this should not work but the idiosyncrasies of Windows 10 are another matter. This is highly recommended, and for any Radio-Hams out there I also use this as the audio interface for amateur radio digital modes..

Rated 4 out of 5 by from Surprised It is a basic little box and software BUT for £25 it is well worth the money. Highly recommended.

Can this card be configured to have 8 microphone inputs?

I am looking to record surround sound live in the field
Asked by: Jamesiow
No it is purely mono or stereo, you would need another interface to record in this mode.

windows 10

is it compatible with windows 10
Asked by: hotukguy
Yes this should work without any major problems. Just plug and play. Go into Sound properties (Windows/ cogwheel/ sound settings) and look for USB audio device, once cofigured it should allow you to use either the PC output or the StarTech one. The Startech is infinitely better sound quality. The Headphone output may need be via the "Front loudspeaker" on the StarTech interface, Windows 10 always seems to have its own mind. I don''t know much about surround sound settings or the SPDIF, although the latter does appear as an input option on Windows 10, so experiment may be required. As a listening souce for recorded music or live streaming this is great and easy to use under Windows 10.
