No Sound on HP Elitebook 820 notebook

hi

I have Wheezy with LXDE installed on notebook HP Elitebook 820 and no sound.
Howto configure Wheezy to load snd-hda-intel module automatically at the startup?

I think more information is required here. I am guessing that Debian sees your sound cards, just not in the order that you want them to be seen. In other words, if you do this command:

Code:

aplay -l

you probably see a list of valid sound devices.

Is this correct?

If so, I think you want an .asoundrc file in your home directory, marking what card you want to have set as your default sound device.

Can you paste what aplay -l returns?

It seems the audio card was not properly recognized:

Code:

# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 1: Intel_1 [HDA Intel], device 0: STAC92xx Analog [STAC92xx Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

# lspci | grep Audio   
00:03.0 Audio device: Intel Corporation Device 0a0c (rev 09)
00:1b.0 Audio device: Intel Corporation Lynx Point-LP HD Audio Controller (rev 04)

# head -n 1 /proc/asound/card0/codec*
Codec: Intel ID 2807

Sound is by default in mute state in new installation. Use alsamixer to unmute and set volume.

When I try to start alsamixer get this message:

Should I not have here HDA output?

Code:

$ cat /proc/asound/card*/id
Intel
Intel_1
