Sound in gutsy is strange .. I get five channels in alsamixer -- PCM, Headphone, Speaker, Line In, Mic.
PCM is set to full. If speaker is set to full volume and unmuted, both the laptop speakers and headphones play.
If I mute "PCM", everything stops playing.

The strange parts --
If I mute "Speaker", everything stops playing, even the headphones.
If i mute "Headphones", the speaker stops playing, but the headphones play.

Hence there is no way to have only the speakers play, and the headphones muted. Can you please tell me what I must include and how to proceed ?
Thanks !
