[rithuarjun]

Hi,

I am very new to Ubuntu as well to linux. I am using Acer 5920 Laptop with Windows XP Professional and Ubuntu Hardy Heron Linux winth GNOME in dual boot mode. Ubuntu is working fine only thing is the sound is coming out from the laptop speakers but i can able to hear the sounds from the headphone when it's connected to the corresponding port. Moreover the sound effect is also not quiet good in ubuntu when i campare the same with windows. In windows the laptop speakers are working fine.

Kindly help me in this regards,

Thanking you,

Awaiting response!!!!

You may have to manually set the option for your sound card. Please open a terminal and run the following:


lsmod |grep snd

You should see the module snd_hda_intel loaded, if not just post the output here to this thread. Now we check the Alsa Configuration reference guide to see which model we need:

http://www.mjmwired.net/kernel/Documentation/sound/alsa/ALSA-Configuration.txt#757

According to the list your model is listed as 'acer', so open a terminal and issue the following command:


echo "options snd-hda-intel model=acer" |sudo tee -a /etc/modprobe.d/options

You could also use this command instead:


sudo gedit /etc/modprobe.d/options

then add the string 'options snd-hda-intel model=acer' minus the quotation marks and save the file. Next time you restart your computer the headphones should work.
