I have the Latitude E6500 and it works fine right out of the box with gentoo 2.6.27 kernel and the alsa that came with the kernel (1.1.17?) With the internal speakers, it is loud and easy to hear. With headphones plugged in, the volume leaves a little to be desired, but it is usable. HDMI audio output (DisplayPort) is not yet working for me. - Jeff On Fri, Dec 26, 2008 at 6:19 PM, Laurent Pinchart <laurent.pinchart@xxxxxxxxx> wrote: > 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. > > The sound card is an HDA-Intel with an IDT 92HD71B7X codec.
