I m using creative 2.1 speakers. And snd_hda_intel module for MCP61 AC'97 controller. MY motherboard is Asus m2n-mxse with built in sound card.
I dont get any sound from my subwoofer and cant see the center control in alsamixer.Also there is no Master control and I cant mute the PCM control which starngely disappears whenever it likes from the alsamixer controls.
help neone?
