I need to record voice on my old desktop PC (Asus P5B-SE - Windows 7). There are three lines on back panel: two with speaker icon and one with microphone icon. Also there are two lines on front panel (one speaker and one microphone) which seems not working.
I connected a smart phone headset to microphone line. Realtek software detected it as microphone. However, it doesn't use microphone of headset; instead, it uses its speakers as microphone! I have to shout in a really near distance (less than 5cm) to record a weak sound.
On my laptop (Acer Aspire E1-572G), when I connect headset, I have three options in Realtek software and when if select headset, it uses both microphone and speaker of headset.
Is it an old incompatible hardware problem? Isn't there any software solution? I've heard about some adapters which separate microphone and speaker lines.
