My computer is windows 7, HP Desktop, I bought an external sound card, StarTech
Had it for a while, I bought the sound card because my onboard sound is horrible. realtek chip on the motherboard extreme low quality trouble recording sound with microphone. I had the same problem on my older computer windows xp compaq desktop, with bad quality sound because of realtek chip. Replaced with an internal sound card, microphone recording then worked.
Went with an external sound card for my newer windows 7 hp desktop computer, problem is, all the external sound card is doing is playing my onboard sound from the realtek chip, including the same horrible microphone quality. I thought an external sound card was like an internal sound card ? That the external sound card was used to replace the onboard sound, but it doesn't seem that way ?
