I have update my linux to 9.04 before a few days, and since then (I am not sure if immediately) I can not hear sound in my linux.

When I boot to windows, I do hear sound, so I know it is not an hardware problem.
Also the linux before work with sound and I could listen to music and movie.

But now I can not and I can't get why.
:confused:

Did you check all the volume levels and mute switches/checkboxes in gnome volume applet/manager?

Check if "User Priviledges" in "Users and Groups" have "Sound devices" enabled. What is your sound card? Sometimes, you may have to load your drivers...err..."soundcard drivers" that is..:D. After you make sure the above in "Users and Groups" are enabled, try "alsamixer" in a terminal...If it works without displaying an error message, sound oughta work...

Have you tried AlsaMixer (http://en.wikipedia.org/wiki/Alsamixer)?

who can I do this check?

As for my sound card, I think it is on board, I check the list of my computer item and I don;t find there sound card so I think it is on-board sound card.
The computer is ASUS.

I have installed it right now.

I will restart and see if it can work out.

I have restarted my computer and the device driver is AlsaMixer.
I go to youtube and I still hear nothing.

maybe it is about User Priviledges setting.
However I believe it is already enable.

How can I check it.

If your sound still isn't working, this can mean that your new Linux kernel has no support for your soundcard/soundchip. In this case you can always download the alsa source code, unpack, configure and install it.

ALSA SoundCard Matrix (http://www.alsa-project.org/main/index.php/Matrix:Main) displays supported soundcards/chips.

I doubt it is a problem of the kernel not supporting this soundchip, because it worked before on a previous install. It is very unlikely that a sound chip is no longer supported.

You might want to google on your sound chip.
lspci in a terminal can give you more information.

Very unlikely yes, but it is possible to create a Linux kernel where you choose to scale it down, remove unwanted drivers etc etc.. and I don't know what's included in an Ubuntu Linux kernel.
