Bug description:
There is no way to reset the ALSA state from the mixer applet.
Several users have found that they lose sound, and that the problem
turns out to be an asound.state file which does not work for their
hardware. It has not been established how the file came to be corrupt
or whether the problem was caused by upgrades to newer versions which
did not handle the file as written by the previous version. It has not
been established what aspect of the asound.state files caused the
problem. But several approaches can fix the problem:
1. Removing the ALSA modules, deleting the asound.state file, and
reloading the modules. This is difficult to do for non-expert users,
because applications such as the Gnome mixer and volume control can be
using the modules, preventing their unloading.
2. Removing the ALSA modules, and editing the asound.state to an
ultra-minimal state that reflects only the primary card, and reloading
the modules.
3. Invoking the alsa-utils "reset" option. On Ubuntu, typing this
fixes the problem for Intel sound cards:
/etc/init.d/alsa-utils reset Intel
The latter option is thought to be best, because it doesn't require
unloading and reloading modules.
It would be very useful to be able to invoke that "reset" command from
the GUI Gnome mixer applet, which is why this bug has been filed on
that.
