No sound through speakers in Lucid Lynx

Strange issue to spend a couple of hours over the weekend! Was trying to watch some catchup-tv on my laptop, the video was perfect but there was no sound from the speakers. Without much thought, I just stuck my headphones into the jack and wallah, there was sound! So something was wrong here. This laptop had the most recent updates on Ubuntu Lucid Lynx as of July'2010. After a few pages advising me of technical support for hardware issues and soldering problems, I was just trying to see which were the "sound-manager-applications". Turns out - ALSA and PulseAudio. Reinstalled ALSA and rebooted - no results. Didn't guess initially that I should try the same with PulseAudio. But that was the solution!

sudo apt-get remove pulseaudio

Reboot

sudo apt-get install pulseaudio

Sound should be up straight-forward. Reboot, if necessary.

If the sound is low/feeble -
(a) System-->Preferences-->Sound Check sound levels.
(b) Do the same with alsa-mixer

I want to buy a house in Costa Rica, because I like the climate there. For me costa rica investment opportunities is the best option for me. I just imagine a tropical day where I can make a lot of parties all the time. I am interested to buy a big speakers and to put loud music.
