Comment 29 for bug 225749

I discovered this morning that my sound (audio) applications are broken.

I suspect since Hein, upgraded his system without any problems, that I probably used an incorrect procedure when I upgraded the kernel header and image packages on my laptop yesterday.

Basically I downloaded the two kernel deb packages to a temporary folder on my desktop (see previous message entry above). When I clicked on one, the gdebi-gtk 0.3.8 GUI deb installer dialog box opened. A message stated that all dependencies were satisfied, and to click on the button to install. I did this for the kernel header package first, and then the image package.

I re-enabled my on-board network interface in CMOS, and then from the Grub menu I launched into the upgraded Ubuntu 8.04 kernel 2.6.24-18-generic package. The system booted into the desktop without dropping to the BusyBox prompt, and I was able to browse the Internet. It was only this morning that I realized that I had no audio.

If I launch into the earlier kernel from the Grub menu -- Ubuntu 8.04 kernel 2.6.24-16-generic, then the audio works fine (of course I still have to disable the on-board network interface when launching into this version).

My question is --- should I have used the console command line installation procedures, and if so, what options or switches should be used, and I'm assuming I should have used the apt-get utility . This is my first time at manually upgrading kernel headers and images.

I've attached an archived Audio_Issues.tar.gz file, which contains three text documents. Two of the files show the lshw, lspci, modprobe results for both the 2.6.24.16-generic configuration, and the 2.6.24.18-generic configuration (broken audio). The ls_comparison.txt file is a comparison between the /lib/modules/2.6.24-16-generic/ directory and the /lib/modules/2.6.24-18-generic/ directory. which presents a big clue that procedures were not executed properly.

Any assistance would be greatly appreciated, thank you.

Sincerely,
Keith Neal
