headphones - debian dell inspiron snd_hda_intel


I am working on Debian with a Dell Inspiron.

When I boot up the laptop with headphones plugged in, they don't work.

When I boot up with headphones not plugged in, they only work the first time I plug them in. (I can't take them out and plug them back in again.)

dan:/home/dan# uname -a

snd_hda_intel


Now, I dual boot with Mandriva, and on Mandriva it works fine. Some files in there may be of some help to us; let me know which ones. (Actually, I think it's because it's a newer kernel on Mandriva.)

Hi secretlydead, Updated alsa modules may very well do the trick. As far as configuration files go, have a look at
Code:
~/.asoundrc
and
Code:
/etc/modprobe.d/sound
, there are alsa options you can append there.

For the options available see ALSA-Configuration.txt or ALSAConfiguration.txt, mine is at
Code:
/usr/src/linux/Documentation/sound/alsa
.

You may also want to check your mixer settings, looking for
Code:
jack sense
.
Good luck. ;-)
