i am very new to this forum. came with a problem.

i am using Compaq Presario SR 1630IL desktop. before describing the problem with me, i would like to give the details of my system,

Intel Pentium 4, 3.06 GHz processor
Intel 915GV chipset
1 GB of RAM
MS-7174 motherboard, Manufacturar MSI, HP/Compaq motherboard name: Graphite-GL8E
Sound Card: Realtek ALC 880 chipset, High Definition Audio

I have a dual booting (windows and ubuntu) system with ubuntu 9.4 as the default one.

Now the problem starts with me.

In windows I do not have any problem with the sound, but in ubuntu the sound is very less. I have a Creative 2.1 channel speaker system with subwoofer. If I put it to the full volume then only i can listen the sound. latter i have discussed with these guides:

What happened is that after completing the installation and selecting everything to pulse audio sound server, i am being unable to open the padevchooser (the icon is there in Applications / Sounds & Video but is not launching). So i could not go forward and still in the trouble with the sound.

Checking alsamixer command in terminal shows everything 100%.

Keenly requesting everybody to help me in this regard so that I can get the sound from my PC in ubuntu.

With kind regards
