USB Sound Cards

Are these USB Sound Cards any good? The reviews I have read say otherwise.
I want to use one for a Discriminator tap.

Are these any better?

I like this one more because it have a line-in port. Do I need that or can I use the MIC-In just as well?

I use them on one of my 4 feeds.. They work good but you may need to attenuate the input from the scanner to prevent distortion. Listen to the Harford County Maryland Fire, EMS and police feed on broadcastify.com if you want to hear one live. It is being fed from the line output jack on a HP-1 scanner

I was referring to the USB audio cards not the optical USB interface in the last post

USB sound cards are ok. I would pickup a handful of them cause they do tend to just stop working for no reason. You will need to shut off the mic input gain setting via the sound settings/recording properties. If you not running a feed I would just consider using r820t sdr for disc audio via SDR#

My setup is here.

Do you have the gain setup properly and what app are you using? sdrsharp or hdsdr also what antenna are you using on the 820t
