XPS M1530 Audio Popping and Crackling Fix

Popping and crackling of audio on the Dell XPS M1530 has been an ongoing complaint of many users. The solution to this is rather simple, however. The problem seems to occur when the CPU throttles down. If you’re running Vista, you simply go into the advanced power options and set the minimum CPU frequency to 100% as shown in the attached images.

Hi,

Please first connect your network card to the wireless router using an ethernet cable (also known as a LAN cable).

Then please follow this procedure:

Step 1: Open Terminal from “Applications->Accessories->
Terminal”

Step 2: Run the following commands (copy-paste the lines below into a Terminal, press enter after each line)

sudo aptitude update

Step 3: Run the following command

gksudo gedit /etc/modprobe.d/blacklist.conf

# Add the following line to /etc/modprobe.d/blacklist.conf:

blacklist ssb

Step 4: Run the following command

gksudo gedit /etc/modules

# Add the following 2 lines to the /etc/modules file:
