Hi everybody,
I've received a brand new Dell Latitude E6500 and found out that the sound card wasn't exactly well supported by ALSA.
Sound is barely audible (so faint that I'm not even sure if the proper sound is output or if I just get garbage), with some loud noise here and there that seem to correspond to the saturated audio data parts.

Anyway, this problem might be related with the volume-knob. Install hda-verb and try the following
hda-verb /dev/snd/hwC0D0 0x28 SET_VOLUME_KNOB 0xff or hda-verb /dev/snd/hwC0D0 0x28 SET_VOLUME_KNOB 0
