3.2.0-rc7 alsa-info shows that the headphone jack is plugged, thus the speaker is muted. It's natural that the noise goes away in this state. Apart from that, I see no obvious problem in 3.2.0 output. Does the problem still happen when you disable "Auto-Mute Mode" mixer enum? % amixer -c0 set "Auto-Mute Mode" "Disabled" Also, try to pass algin_buffer_size=0 option to snd-hda-intel. I don't expect much that this will influence, but at least, it's a difference between 3.0 and 3.2.
