Package: acpi-support
Version: 0.142-8
Severity: normal

The hardware "mute", "volume up" and "volume down" buttons on my X220
used to correctly adjust the sound volume. Now they do nothing at all.

I wonder if this is because the events generated no longer match the
patterns defined in the config files; for instance the "mute" button
generates:

  $ socat /var/run/acpid.socket -
  button/mute MUTE 00000080 00000000 K

whereas the file says:

  $ cat /etc/acpi/events/thinkpad-mute 
  # Volume Always Mute
  event=ibm/hotkey HKEY 00000080 00001017

Similar observations can be made about the volume up and down keys.
