Hi,
I am using Windows XP Sp2 .
Sound card - CMI8738 4CH without SPDIF, Line-in and rear speaker o/p share the same jack.
Microphone booster is enabled. There is no advanced options as to adjust the dB. If I record without Boosting,the volume is tooooo low even when the mic slider is at the top in the record setup. So I enable the Mic booster. The problem is the noise that accompanies when recorded with the Booster on. I know its the signal to noise ratio that causes this when the original signal is amplified. But I want to bring the noise down somehow at least to a bearable extent.
Can anybody help me with this?? Exempting the option to go for a better soundcard.

Coz my sound card works best except for this.
Thanks in advance.
Regards,
Chandhini
