View Full Version : [ubuntu] [SOLVED] Headphones on Ubuntu 8.04 not working
August 28th, 2008, 10:46 PM
The sound from my speakers work fine, but I have absolutely no sound coming from my headset... (although it does play the "welcome" sound when it's plugged in).
I've installed ALSA, changed the settings in Sound to the headphones, but nothing happens (My headphones connect to a USB port).
I reformatted my computer (where the headphones worked quite well, but I had no external speaker sound.)
Is there some way I can fix this? Any help would be much appreciated!

Have you checked all your volumes in volume control?
August 28th, 2008, 10:55 PM
Yep they're set to full volume.

You might try
sudo apt-get install linux-backports-modules-generic
It seems to have worked for other people with the same card.
August 29th, 2008, 08:25 PM
I don't seem to be able to find the linux-backports-modules-generic package.. Is there a website i can download it from?
August 29th, 2008, 08:28 PM
If you can't find a backport, just a guess; make sure you have backports active in your Software Sources (System->Administration->Software Sources).
August 29th, 2008, 08:31 PM
Yep I checked the backports. (That's on the Updates tab, right? I also selected all the names in the 3rd party software list
August 29th, 2008, 08:34 PM
Then, if you're doing this through terminal, that's probably your issue; you're not specifying the version.
Instead, use synaptic package manager, do a search for "linux-backports-modules" (omit "Generic"), and you'll see the actual package is called linux-backports-modules-##VERSION##-generic
Alternatively, I think you could just do linux-backports-modules-hardy-generic to get the latest, whatever it is.
August 29th, 2008, 08:39 PM
I searched on synaptic for "linux-backports-modules" and I found a whole bunch of options..
*Edit* Oh ok I'll give that a try, thanks
August 29th, 2008, 08:54 PM
hmm didn't work.
August 29th, 2008, 10:34 PM
Sorry, I should have pointed this out earlier. If you still haven't been able to install the backports-modules, run
gksudo gedit /etc/apt/sources.list
Do a search for the term 'backports'. Uncomment the lines (remove the # symbol from in front)
# deb http://es.archive.ubuntu.com/ubuntu/ hardy-backports main restricted universe multiverse
# deb-src http://es.archive.ubuntu.com/ubuntu/ hardy-backports main restricted universe multiverse
Save the file and run
sudo apt-get update
and you should now be able to run the original command.

It couldn't find the package, although I'm installing some version backports-modules right now, in Synaptic.

For some reason, my headphones seem to be working now when I change the settings in Sound from Autodetect to USB Media.
Each time I want to switch from headphones to external speakers, I have to change all the settings... Is there a way to fix "audtodetect"?

You can set the default device as follows
to see how alsa identifies the available devices. Then run
asoundconf set-default-card xyz
where xyz is the name of the device you want to use, according to the output of the 1st command.
Reboot for changes to take effect.
August 30th, 2008, 06:31 PM
OK well this about wraps it up. Thanks for your helpful posts, they were much appreciated!

On my system, I found the xyz under number 1, thus in Terminal, I typed
asoundconf set-default-card 1
Then I closed and re-opened my browser (Mozilla Firefox) or restarted my system.
Note, if you unplug my usb speakers, my laptop speakers will take over. In order to re-establish contact with the usb speakers, I need to (plug them back in) restart the system.
