Description: Audio fails on resume from Suspend and Hibernate
Systems Affected: Inspiron E1505n, 1420n, 1525n and XPS M1330n.
Impact: No sound after resume from Suspend and Hibernate

  • Create a script named 99-restore-volume.sh in /etc/acpi/resume.d/
amixer sget Master|grep "Mono:" | while read m p v j
  amixer sset Master 0
  amixer sset Master $v
  • Change user and group ownership of the script
chown root.root /etc/acpi/resume.d/99-restore-volume.sh
  • Change permissions of the script
chmod a+x /etc/acpi/resume.d/99-restore-volume.sh

Only in XPS M1330n:

Download Dell's custom linux-backports-modules (l-b-m) package linux-backports-modules-2.6.22-14-generic_2.6.22-14.50_i386.deb. This custom l-b-m is not available on any of the Ubuntu repositories, it is only available on this site.

To install, run:

$ sudo dpkg -i linux-backports-modules-2.6.22-14-generic_2.6.22-14.50_i386.deb

And reboot your system:

$ sudo reboot

Fix: In progress. See LP146690.
