No speaker sound on HP with xubuntu

Broder · 12-25-2008, 02:04 PM

I just installed xubuntu on a HP 6830. Everything seems to be working straight out of the box except sound from the laptop speakers. The sound card is working because there is sound through headphones but no sound coming for the laptop speakers. I've never used either xubuntu or a laptop before so it's possible I'm missing something really obvious but can't for the life of me find it. There doesn't appear to be any external hardware switch for the sound and the only place in the xubuntu menu I can find sound is through the settings and everything is switched on.

Anyone have any ideas?

What chipset does the sound card device use?

will you need to unmute your sound mixer. if that is not the problem you need to make sure your card and module is loaded. post these type in a terminal lspci and your lsmod.

So the correct module must be loaded.
Drakeo is right - you need to check your sound mixer, and turn up the volume control for the speakers. (On my laptop, my "speakers" are called "Front", don't ask me why!). In KDE I can access my mixer when I L-click or R-click my volume control.

If you can't find your mixer (it really should be there already), try installing these packages:
xfce4-mixer
xfce4-mixer-alsa
I am not an xfce user, so don't know if you need both or just one of them

Well I was thinking if it was an intel hda chipset it may require a special options line for sound to work on all channels. That is what I had to do for my hda-intel ICH9. I played with many distros and none got it right.

Thanks for all the advice guys. So far, no luck.

The chipset is
Mobile Intel® PM45 Express Chipset ICH9M-Enhanced

Everything is un-muted in the sound settings, the xfce4-mixer is giving me two options for device: default and hash0: HDA Intel , and then wannabe master options are : Master, PCM, Front mic, Front mic boost etc.

Brian: can you elaborate a little about the channels?

Drakeo · 12-29-2008, 05:47 PM

type alsamixer and un-mute the pcm. or if you have the little icon right click it go to mixer and un-mute it. if that does not work then check into pulseaudio bug.

Brian1 · 12-29-2008, 06:29 PM

My notebook HP dv7-1020us has the same model number sound chipset family. It may vary in the way it is wired. Those Intel can be wired so many different ways. Now I dont know Ubuntu but in Fedora 9 I had to add a line to my /etc/modprobe.d directory and called it alsa-base. Check this post on the sound and the file I created and line I added to it. Reboot. Only thing i have no sound on is my headphone jack. If it works let me know and whether the headphone quits working after this change.

Look at item 5 in this post. Like I say I dont know if Ubuntu works the same as for modprobe stuff. You may have a file called .etc.modprobe.conf and if so then add that line to it. If you have a different options line like the one in my post please post it so I can check it out. Maybe I can get headphones working with it.

Fix: The sound on Front was disabled as opposed to muted. A friend of mine found a solution by adding the following line of code:

options snd-hda-intel model=laptop enable=1 index=0

to /etc/modprobe.d/options file which forces enabling the speakers on start up.

Thanks for the advice, hope the solution can be of help to others.

Brian1 · 01-07-2009, 03:13 PM

Gave your line a try and does not help me for headphones. It does not make the sound card work either. Returned to mine and raised the volume up on master and headphone and there is sound. But from listen to the speakers then plugin the headphones I have to raise the levels so much. I have to remeber to lower before unplugging or sound will be way to loud. Seen some post mention that the headphones are directly come from the DAC. Some patch has been made. May have to look into that for more info.

Glad you have it working on your end. It is amazing how much those intels differ.

worked for me to on Hp 6930P, thanks

ps
editing alsa-base.conf just open terminal and
sudo -s
sudo mousepad /etc/modprobe.d/alsa-base.conf

Thank you, that was just the information that I was looking for.
