Ubuntu 8.04 no sound on my Lenovo R61i


My ubuntu 8.04 installation is sucessfull. everything except the wireless and sound, is working fine.

I can see the sound icon on the top right corner and i can adjust it's volume. But when i play a song, or do a test sound, it doesn't produce any sound.

When I play song in the rhythmbox media player, i can see the virtualization moving, but no sound coming out.

Please help me out.

Big Thanks.

In this file, I had to add

options snd-hda-intel model=thinkpad-t61p

for Ubuntu 7.10, but did not have to for 8.04. I'd start here, and google for other ideas.

When you have an address on eth interface Network Manager won't manage the wireless interface.
Additional commands to use to assess the state of the interface are:
$ sudo iwconfig
$ iwlist scanning
Anyhow the steps to configure an interface with Network Manager are as
Right-click on the Network Manager icon – it looks like a pair of computer screens on the upper panel. If your wireless device has been detected there should be an Enable Wireless option. Click on this so that it becomes ticked.
If the Enable Wireless option isn't present, then you should left-click on the Network Manager icon and, select Manual Configuration, unlock the menu, select the Wireless Connection, select Properties and disable and re-enable roaming mode.
Then left-click on the icon and select the small button beside the network that you wish to connect to:
You should be prompted for a passphrase or key.
Enter a passphrase or key. The icon will change and if a connection is established the icon will change to a bar graph indicating the signal strength.
If the mouse pointer is hovered on the icon a legend will be displayed with a legend like "Wireless Network Connection to myaccesspoint (82%)".
Information about a connection can be obtained by right clicking on the Network Manager icon and selecting Connection Information.
Hardy Heron works very well with the Thinkpads and other Lenovo.
For sound if it's hda-intel,check this link;

And all it takes is little searching.

Thank you all for your invaluable response. Now I have found out why my sound doesn't work. it's just an on/off button on the keyboard that put my sound to work.

But it looks strange anyway, I did tried this button before, and only at now it works. May be I've got some modules updated through synaptic.

Thanks again, have a nice day.
