[DaBurr]

Hi everyone, i recently installed Ubuntu 10.04 on an 2 year old hp 6700, which was running vista, and everything went smoothly, i realized my sound does not work, everything else worked out, i then found this tip and tried it out in the terminal
sudo apt-get install linux-backports-modules

the sound came back, only for few hours, only to find out it stopped working all
over again. Now i dont know what else to do or try i even reinstalled
Ubuntu and still no sound, the sound icon just has this next to it ---
my computer is a AMD system

Try this. Using a Terminal="Applications->Accessories->Terminal"
Open this file for editing:

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

Insert this line at the bottom:

 options snd-hda-intel model=dell-m4-3 enable_msi=1

Save. Close. Reboot. Check your levels in alsamixer.

 alsamixer

Press <F6> to select the correct soundcard.
Press <F3> to show playback levels. <F4> selects capture levels [or use <Tab>]
Use the left/right arrow keys to select and up/down arrow keys to change levels. <M> to mute/unmute.
Go to "System ->Preferences ->Sound" and make sure the correct soundcard is default and adjust your profile on the hardware tab.

No joy? Change that previous entry to this and reboot:

options snd-hda-intel model=hp-dv5 enable_msi=1

Thank you so much! That did it, i was seriously little skeptical that it would work, once i rebooted, the ubuntu startup sound came on , and the alsa mixer shows the value working. Thank you very much!

One down, a million to go.
If you would please, mark the thread as solved using 'Thread Tools' up top.

This works for my HP Compaq nx6325. Thanks a lot!
