I installed Ubuntu 9.10 x64 recently. Up until now I've been on 32 bit Ubuntu. For the first time since installing it, I went and tried to play a Youtube video. There was no sound. So a quick test to the system reveals that nothing will play sound (And I've tried turning the volume too full, as some have said output is quite quiet, but there is no sound at all). Further research shows that in sound preferences, the only output device listed was Dummy Output.

Why would it work in 9.04 x86 and not 9.10 x64? While booting up, and occasionally with the sound preferences dialog open, I get a loud click (even though it isn't recognising my sound card).

It's a Dell Studio 17 laptop. I'm not sure what the exact model of sound card is.

  • 9.04 x64 worked fine until a kernel update a few months ago. I upgraded to 9.10 x86 (32 bit) and it started working fine. Not before I swapped out the motherboard, video card, cpu, and then everything back. I now have the original system with working sound and a different Ubuntu distro. So, yeah, 9.04 x64 has sound driver issues.

There are no 64-Bit drivers for your sound card that came with the disk. I would check on the vendors website and see if they have released 64 bit drivers.

  • The driver is a good thing to check, one nitpick though: most vendors don't provide drivers that work with Linux, and just about everything should come with your kernel. Mar 1, 2010 at 2:23

Turns out that there was 64 bit drivers available. However, they didn't work on the old kernel I was using (and I forgot to update my menu.lst so I was still booting the old 9.04 kernel).

most likely you just don't have the sound driver installed. Go to system>administration>hardware drivers and make sure its not waiting to be downloaded there. Or you could go to Dell's website and see if they have any linux drivers available for download. And as a last resort you could search Google to see if any one has made a driver or fix for this problem. good luck.

  • Dell does not provide drivers for Linux. Most hardware vendors do not. The Linux developers make most of their own drivers, and they come with Linux. Finding drivers online works for Windows, but for Linux it won't help much. Mar 1, 2010 at 2:20

Hey, I had the same problem and solved it. Just don't install the "modem driver" the system ask you to install at the first start up (in the case you did it, just remove it!!) and you'll have the sound drivers working. Please check that and let me know if worked for you!!

  • It didn't ask me to install any modem driver.
