After upgrading from 9.10 to 10.04, no sound output

[KOGA Takeshi]

Hello all

Last week I upgraded my ubuntu machine from 9.10 to 10.04.
It was succeeded on the whole, and I have gotten the issue of this mail subject.
On ubuntu 9.10, my machine was fine to output the sound. But now state
is different.

I find below state on my machine.
I suspect that /proc/asound/version should be 1.0.22.
If anyone have a idea to do that I should do the next, please tell me it.


$ cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.21.
