Does it work from the live disk?<BR>
I had a similar failure with my sound card on 9.10<BR>
1. I did an upgrade over the wire, which had always worked great with Ubuntu before.<BR>
1.1 Sound fails - card is seen by the system but not seen by pulse-audio or any other GUI-side utility<BR>
2. Burned an iso of Ubuntu.<BR>
2.1 Bare-metal install <BR>
2.2 Sound failed (same apparent issue as 1.<BR>
3. Worked it over at the Install Fest with wiser help. <BR>
3.1 The issue seemed to be that the installer program was jacked up, and not able to set the mods right<BR>
3.2 There were different link numbers to the kernel modules related to this bit of hardware. Found with <B>lsmod</B> in live and installed sessions.<BR>
4. Installed Kubuntu (clean install) <BR>
4.1 The sound card was automagically available for use.<BR>
4.2 The modules had the same linkages as they did from a session off of the live disk<BR>
What's different? Mine was an HP dv6000 laptop. Apparently, lots of people were having trouble with this model and sound.<BR>
What doesn't work now? My hp multimedia button-bar at the top of the keyboard is not rigged up in Kubuntu. It is still limping because of that.<BR>
<BR>
You might be able to look at kernel modules related to the DVD drive. Since the previous version worked, it would make sense that there was a similar issue for your situation as for mine, though it is a different kind of hardware.<BR>

This was something I hadn't seen for listing hardware lshw. <BR>

Another newsletter from the Slow Learners Academy:
I finally upgraded my Ubuntu installation to 9.10 lasty week, figuring
enough time had passed for others to have worked out most problems.
Not so--the thing doesn't know the machine has a DVD drive in it. Pop
in a disk, nothing happens. Click on the cdrom icon that appears in
Nautilus, get the message that no such device exists. Try it different
ways, get variations on the message: "/dev/scd0 does not exist,"
"/dev/sr0 does not exist." I check, sure enough, it doesn't exist. My
first thought is, "Well, then, I'll make it."
I spent a long while Saturday looking on the Ubuntu forums &
elsewhere for folks having the same problem, & there were many. Lots
of other folks being helpful, but none of the tips worked for me. They
all seemed to be predicated upon the device being there, & it wasn't.
Okay, blunt object time. I made /dev/sr0 w/ touch, changed the group,
set the permissions, created a symbolic link to /dev/scd0, & it
worked. However, comparing it with the other files in dev, noticed it
should be a block file.
Haven't done that before. Is mknod what I should use to create the
device file? Is there a preferred way?
