Low sound with ALSA and Intel sound card

Hi, I'm having some issues concerning my audio, comparing to Windows, the sound is quite lower and sometimes in the middle of a track, there's some quick buzz (I use ALSA by the way). There's how to get a louder sound and fix this buzz problem? I use MOCP to play music. Here's some info:

cat /proc/asound/card0/codec#* | grep Codec
Codec: IDT 92HD71B7X

Have you checked the volume settings with alsamixer?
