Comment 11 for bug 77214

I'm new to Ubuntu and I guess you could call me a Linux newbe as well, However since I experienced this problem and there is no direct solution for this "bug" written here I decided to post my experience. I installed Hardy on a FS Lifebook S7020. No sound was heard after completion of the installation or when using the Live CD.
I worked around this problem by double-clicking the master volume icon in X. After I upped the volume of the internal speaker which was set to 0 sound was played through the speakers of the machine.
Ps. First I tried to accomplish this by using alsamixer (in a console) as suggested in the debugging guide. However I was probably unable to change the volume of the internal speakers as nothing happened after I unmuted and upped the levels of all available volumes.
