Bug Description
I Installed ubuntu 9.04 X64 from DVD , and applied the latest update.
How ever I found a bug with the hibernate function. I tried hibernate and resume , everything works fine except the speaker. The speaker is mute no matter what I do in ubuntu.
Things are a little tricky here . Although the speaker wont sound , but if I plug in a headphone , I can hear the sound . I searched the internet and tried cli command " sudo alsa force-reload " , it says :

I don't know whether it is good to see that . But what happen is no matter how I mute and un-mute the sound , or I change the master volume , the speaker remain silence , and the headphone remains good.
And , the device I'm using is HDA Intel ( Alsa mixer ) which I found from the volume control pannel.
Things is fixed like this : I boot my T400 with vista (which I have not delete yet for something like this which I hope it wont happen but it happened) , and I see the vista recognize the sound as mute condition . Simply change mute to un-mute in Vista wont work neither , I have to un-mute and play a song from vista , and then I reboot to ubuntu , speaker works fine now .
This bug annoying me most , sine my laptop use hibernate and resume a lot , if every time I have to reboot to vista to fix it then I have to change my habit to shutdown rather than hibernate , that is bad...
Hope u guys can fix this , thanx a loooooooooooooo
For another bug , I installed another ubuntu 9.04 x64 with live USB creator.
Here is what happened , in the newly installed ubuntu which I can affirmative that there are sounds , I click reset , and change to the previous installed ubuntu , the sound become automatic mute and master volume change to zero.
But thank god I un-mute it change master volume change to 100 ,the sound come back , no need to boot to VISTA.
Is this something about that ubuntu can't remember what status the sound was before resume or reboot ?
