Hi, i've got an hda/alc268 card (pci id: [8086:284b], subsytem id: [1025:011f]) on my laptop, and the sound is ok for the loudspeakers but it is very very low for the headphones (the volume is at the top in the mixer, if i reduce the volume in the mixer the sound gets even lower). Under windows vista the headphones work well (ok, worked, before that i removed windows from my computer). I am using alsa hg, the most recent version at the moment i'm writing this e-mail. I there is any experiment that i can do or if i can help in any way (i know C very well) to fix this bug just let me know, and i'll be happy to contribute. More information about the hardware follows. Thanks! -- Ciao Maurizio http://stregatto.wordpress.com "Well we all shine on Like the moon and the stars and the sun" (John Lennon) lspci entry: 00:1b.0 Audio device [0403]: Intel Corporation 82801H
