No sound with hp 6735s, ATI SBx00 Azalia (Intel HDA)

[green traffic cone]

Evening All,
I'm rather an Ubuntu Noob, so please be gentle
I've just purchased an HP 6735s laptop and have installed Ubuntu 8.10. I'm not getting any sound through the speakers. Strange thing is it's fine through headphones.

I've played around with the audio settings and not been able to get anything, also tried sudo apt-get install linux-backports-modules-intrepid-generic with no improvement. I've asked around and no one seems to have any ideas. Oh and i know the speakers work as they are fine in Vista (sorry for the bad language).

any ideas would be gratefully received
cheers

I"m having the same problem with a 6535b, any luck yet?

[dhcrawford]

Fixed!

Running 8.10

I am running ALSA exclusively and ran all the updates

I used this article as a basis for the fix:

https://help.ubuntu.com/community/HdaIntelSoundHowto

__________

edit /etc/modprobe.d/alsa-base

add at the end of the file:

options snd-hda-intel model=laptop

reboot
___________

Et Voila!

PS. I spent the better part of a week trying to figure this out under Fedora. It took me a few hours to get it right in Ubuntu.

You're a genius! Worked first time and such a simple solution too. Start up music scared the living daylights out of me though. Anyway thanks for the help, I owe you one

This also worked great on my HP Pavilion dv7 1245ca with the same sound card. Thanks very much! Ubuntu rules!

Ok this is weird, but it worked for me, and then a pop up window told be to set the default sound card by the command "asoundconf set-default-card". The only card I have is "Intel" (output from "asoundconf list"). Now it doesn't work!

I can hear the login screen bongos, but the speakers stop working when I log in. No start up music. I think this means that it's a user setting that's screwed up.

I also added "options snd_hda_intel model=laptop" to the end of "/etc/modprobe.d/alsa-base"

Should I just uninstall all pulseaudio and alsa packages and user directories and start over again?

[lennyleonard]

If you double click the volume control icon, and choose "preferences", it allows you to choose more sliders for different inputs/outputs. Maybe one of them is muted by default, but not shown. That was the problem with my microphone input.

I have problem with microphone at this soundcard.

I write code to '/etc/modprobe.d/alsa-base.conf' , but stil don't work.

Worked for my HP 6535b as well

although I had to use

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

in order to edit the file

This tweak is better than the suicide hotline
