apport information
** Tags added: apport-collected
** Description changed:
My hda power-save never produced problems until the recent update of
linux-backports-modules-alsa-karmic-generic that installed ALSA 1.0.22.1
Now I have the cracking sound after a little more than 10 seconds of
idle sound.
The cracking is not as strong as it is on other computers, but it is
there.
I saw it is tagged "Fix released" on the dozens of similar bug reports,
but in my case it is the opposite: power-saving was always working fine
until recently.
I apologize if there is a fix about this problem that is available
somewhere which also fixes the problem with these devices.
But with my standard Karmic install I still experience this problem.
