Hello,

I re-installed below packages with synaptic package manager.
But my machine status has not been changed.

alsa-base            1.0.22.1+dfsg-0ubuntu3
linux-sound-base  1.0.22.1+dfsg-0ubuntu3
alsa-utils              1.0.22-0ubuntu3

Next I would upgrade alsa to 1.0.23, but it hasn't been released on
official packages.
It's possible to install the alsa 1.0.23 with compiling from source code,
but I don't want to do so.
Because I worry about my linux skill and the conflict of the official package
update in future.

I found below webpage. It is expected that the package update related sound in
future.
https://edge.launchpad.net/~ubuntu-audio-dev/+archive/ppa

So I wait alsa-* package update in official for the present.
