Well, I had sound problems myself, but I'm a complete newbie. Since you said that ANY help would be appreciated I am posting my fixes.
1. Install and activate pulseaudio (from https://wiki.ubuntu.com/PulseAudio
Warning /!\ This section only applies to old, unsupported versions of Ubuntu. Ubuntu 8.04 and higher installs PulseAudio by default and no extra configuration is needed.
Here's how to install it, as of Dec-08-2007, on Ubuntu Gutsy Gibbon 7.10, with PulseAudio 0.9.6
Open a Terminal window.
Type the following:
sudo apt-get install libasound2-plugins "pulseaudio-*" paman paprefs pavucontrol pavumeter
Now, type the following:
gksudo gedit /etc/asound.conf
This will open /etc/asound.conf in a Text Editor as the root user.
Normally on Ubuntu 7.10, this file will not exist, so we're creating it.
Paste in the following:
The top two will create new output and input definitions for PulseAudio, and the bottom two will set PulseAudio as the default audio device for programs using the ALSA interface.
2. Tweak pulseaudio (from http://pc-freak.net/blog/how-to-fix-pul ... gnu-linux/
Fix problems with Glitches, voice skips and crackling In file /etc/pulse/default.pa its necessery to substitute the line;
load-module module-udev-detect tsched=0
2. Resolve Choppy sound in (Pulseaudio) -> Skype
In /etc/pulse/daemon.conf two lines has to be also substituted:
; default-sample-rate = 44100
default-sample-rate = 48000
3. Change /etc/default/pulseaudio to allow dynamic module loading
It is a good idea to the default settings from DISALLOW_MODULE_LOADING=1 to DISALLOW_MODULE_LOADING=0 .This step is not required and I'm not sure if it has some influence on solving sound in / out problems with Skype but I believe it can be helpful in some cases..
So in /etc/default/pulseaudio Substitute:
3. Install missing python libraries(?)
That pretty much worked for me, see if any of this helps...
