Sound problems in Kubuntu droped audio and stutters

This is sort of a strange problem/puzzle to me.

I had KxStudio running on a dual core/intel chip and an asus mob. It ran great - just about perfect. Then the machine crashed. I had ordered an amd A10 6700 machine to replace the old machine. I decided to try a transplant and put the old hard drive running KXStudio into the new machine. To my surprise it ran great, except the video. The video on the old machine was a card, on the new machine it was running off the chip.

In order to get the video right I installed KXStudio on the drive that came with the machine. The video was a lot better, allowing one to play some graphic intensive games etc.. But the audio stutters and drops. Since this wasn't happening when the other drive was booted, I looked at the settings and copied them but the stuttering and dropped audio continues.

I've have tried many many setting but I cannot get this to stop. Has anyone had this problem. Is it something with the AMD chip? Perhaps it is something w/ Kubuntu? It seems so weird to me that I'm curious to understand what has happened or is happening!!

Kubuntu version?
on console: lspci -v | grep audio
on console: lsmod

the lspci -v | grep audio cmd does not produce any lines. Without pipe and grep it does, not sure if that's useful. lsmod produces a lot of out put. I can paste and send, however I assume that I should do this for both drives?

and thanks for responding..,.

I'm sending this, not sure I'm getting the right info. If it is I'll send the other drives readout

Please try:

lspci -v | grep Audio

This is the results of the cmd.

0:01.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Trinity HDMI Audio Controller

the A10-6700 is supposed to have audio and radeon video - so this sorta checks out.

Since this is a new chip and mobo, give a try by updating the KSstudio distro if it's available.
