As suggested I upgraded. Same as before except now not even the speaker control in the application bar. Please help.


I have Ubuntu 9.10. Headphones appear to work fine. External speakers - nothing. There are so many sound preferences I have no idea what or which combination.

Went to terminal and ran alsamixer which seems to recognize my sound card, though the driver is not listed in System > Administration > Hardware Drivers; the only driver listed is my graphics card.

Setup: I have a Dell 8250. Speakers are plugged into the SB live card. Woofer and 2 speakers using transformer.

Can you provide some information about your setup? – Nathaniel Bannister Mar 8 '11 at 19:53
@Nathaniel Bannister: Dell 8250 Sound worked fine with windows, friend installed 9.10 no sound, so upgraded as suggested, still no sound and worse. – Walter Mar 8 '11 at 20:03
How are the speakers connected? – Nathaniel Bannister Mar 8 '11 at 20:04

I did go to alsamixer and pushed the master and pcm? to 100$ – Walter Mar 8 '11 at 20:08

I've gone all over the place looking for answers, so far this is what I've turned up:

  • The Dimension 8250 had a OEM Soundblastr live that needed non-standard drivers, even under windows
  • I'm reasonably sure that the part in question is a Sound Blaster Live! CT4780
  • Some suggested that while windows output audio on the black port, ubuntu's driver wants it on the green port
  • Some aged suggestions suggested switching alsa for OpenSound
  • I'm not sure how in depth you want to get into this, if there's an onboard, I'd probably just remove the add-on card
  • If you're feeling adventurous you can try: or

I'll keep an eye on the thread

@Nathaniel Bannister: Thanks for your efforts. It came with that card so I doubt if there is another. How about aiding with a partition so I can install windows again? – Walter Mar 8 '11 at 21:35
@Walter, if you look at the back of the machine, is there a second set of ports? – Nathaniel Bannister Mar 9 '11 at 0:27
@Walter if you want to reinstall windows, it's usually easier to wipe with windows, as it's boot manager will erase grub. If you want to dual boot linux after that, then you'd just install again and tell it to split the disk. – Nathaniel Bannister Mar 9 '11 at 0:30
@Nathaniel Bannister: As to the former, unfortunately no. – Walter Mar 9 '11 at 11:58
@Nathaniel Bannister: As to the latter. Beyond my pay grade my friend. A friend wiped my hard disc after a problem. Installed Ubuntu, which as I have said, no probs except for sound. Which is a biggie, I am so tired of hunching over with my headphones, tho no longer a problem as they no longer work. Anyway, I tried to install windows again and it will not, and I assume the reason is there is no partition. I did download gparted-live-0.7. But it does not give me a workable interface. So, no sound...back to Dell for a new pc? – Walter Mar 9 '11 at 12:05
