[SOLVED] How to fix breaking/cracking audio on MSI X320 or similar Poulsbo chipset based laptops on Ubuntu / Linux Mint

Though this fix was tested on an MSI X320 running Ubuntu 14.04, it should work fine on most other Poulsbo based devices. Please let me know your device make, model, if it did / did not work for you.

Just run this command in Terminal:

sudo echo "options snd-hda-intel position_fix=1" >> /etc/modprobe.d/alsa-base.conf

Then restart for the settings to apply.

MSI X320 Detailed Specs

Ubuntu on MSI X320

Note: this document is a work in progress. I'll be adding more info to this as I get more things to work.

I would love to see Ubuntu 11.04 booting up on my MSI-X320. But due to the way they have built this, it needs a bit of work to get things working.

Only Ubuntu 10.04 Lucid Lynx seems to work for now.
Ubuntu 10.10 Maverick Meerkat and Ubuntu 11.04 Natty Narwhal do not even boot into the Live CD.

Till some later kernels get the issues fixed, for now, I'll start with Ubuntu 10.04.
