Ubuntu – Sound not working with Ubuntu 12.10 clean install


Did a clean install of Ubuntu 12.10 from 12.04 and the sound is not working now. In 12.04 it worked out of the box.

I ran hwinfo --sound

hal.1: read hal dataprocess 4222: arguments to dbus_move_error() were incorrect, assertion "(dest) == NULL || !dbus_error_is_set ((dest))" failed in file ../../dbus/dbus-errors.c line 282.
This is normally a bug in some application using the D-Bus library.
libhal.c 3483 : Error unsubscribing to signals, error=The name org.freedesktop.Hal was not provided by any .service files

Not sure how to proceed to fix this. Has also worked prior to this version.

How to resolve this ?

  • I fixed it by running alsamixer, and changing AUTO-MUTE MODE from ENABLE to DISABLE.
