When I plug in my headphone to the computer, speakers're still working although headphone is working too. Do you know how can I solve this problem in Ubuntu 11.04

I have ASUS g50v and when I type cat /proc/asound/cards it gives the list:

0 [Intel          ]: HDA-Intel - HDA Intel
                     HDA Intel at 0xf9ff8000 irq 49

I set my /etc/modprobe.d/alsa-base to below option as suggested in that post

options snd-hda-intel model=g50v

however with all these settings problem still occurs

Thanks in advance :)

I solve my problem: I solved my problem:

first:

sudo gedit /etc/modprobe.d/alsa-base.conf

and open the config file than add following 5 lines to the end

options snd-pcsp index=-2
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=m51va
options snd-hda-intel enable_msi=1

then

sudo gedit /etc/modprobe.d/options

and add followings to this file then reboot

options snd-pcsp index=-2
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=m51va
options snd-hda-intel enable_msi=1

sudo apt-get install gdebi
wget http://www.linuxant.com/alsa-driver/alsa-driver-linuxant_1.0.23.0_all.deb.zip
unzip alsa-driver-linuxant_1.0.23.0_all.deb.zip
gdebi-gtk alsa-driver-linuxant_1.0.23.0_all.deb

-Install the package and reboot. Now speakers should mute when headphones are connected, HDMI and microphones (internal & external) should be working. Open alsamixer and unmute S/PDIF (you can do that pressing “m”). Choose HDMI output from the pulseaudio volume applet (hardware tab) when needed.

Even though the information is outdated on that website. It solved the same problem I had.

its easy just disconnect the speaker pin that was plugged at the back of the computer.

Downvote: This should happen automatically, without any need to unplug anything. –  Javier Rivera Mar 13 '12 at 14:56
