[alsa-devel] Issues with HP DV4 laptop sound after Ubuntu Jaunty 9.04 upgrade

[Guy Stalnaker]

Hello again, Takashi,

Can you think of why a new distribution might be the cause, or a change
that a new distribution makes, that would result in such behavior?  The
new distribution includes a new kernel and a new version of xorg (I
think), so everything on top of the hardware is new. What's damned
peculiar is that the HTML output interface is always recognized
successfully. It's only the Audio device: ATI Technologies Inc SBx00
Azalia (Intel HDA) on pci 00:14.2 that seems to have this issue.

To add oddity to the issue, I brought the laptop to work this morning
and on boot the Audio device was successfully recognized and aplay -l
shows it a card 0!!

I wonder ... do you think that it's possible that a keyboard, mouse,
printer, or some other USB device plugged into the laptop at boot could
affect something like this?  That's really the only difference between
work and home.

Thanks for taking the time to read that long post to the list!!

Guy
