Whenever I start Ubuntu, the sound is missing and I have to key in the command alsamixer (where the third slider is zero) and increase the volume manually. How can I fix this?

PS : i don't mean startup sound i mean that the sound is missing altogather from the songs/ movies everything.

Please check System -> Preferences -> Sound. Check if 'alert volume' in sound effects tab and output volume in 'output' tab is not in mute or near to 0%.
