Hello Gururaj: In principle, Intel HDA (High Definition Audio) support is available with ALSA (Advanced Linux Sound Architecture). However, I have seen suboptimal sound quality and occassional hangs on Dell & Compaq C300 laptops. As you would know that almost all OpenSource/GPL v2 drivers are created by reading the available specs on vendor site, bit of rev engg, it is quite difficult to match the native drivers since vendor specific details are not known. What usually happens is that few months down the line, some new facets of the hardware become known and then a better OpenSource driver becomes available. For the interim, I would suggest that you get your N&S Dept folks to check the settings on your laptop by verifying with the information mentioned at http://bugtrack.alsa-project.org/main/index.php/Matrix:Module-hda-intel Hope this gets you started. thanks Saifi.
