Hi David, Thanks a lot for your help. Here are the results: 1) Did not have /updates/ in the filename 2) Installed the package linux-alsa-driver-modules-2.6.35-28-generic. No change in stuation. Attached the output from http://www.alsa-project.org/alsa-info.sh at this point as alsa-info-report-post-alsa-driver.txt 3) Tried after inserting alsa-base.conf with model=auto. No change. Attached alsa-info-report-post-alsa-driver-model=auto.txt 4) On hda-anayzer, I could not figure out how I can raise the Amp-out values. What I see on node 0x0f is attached as Screenshot-HDAAnalyzer.png
