for some reason there was a newer kernel in /boot/ which was not part of Ubuntu Studio. The installation didn't touch the kernel, but wiped out (as should and expected) all files under /lib/modules
for this kernel.
As a sequence, grub recognized the kernel, being the newest, placed it in top, my son kept selecting it being the default, and so there was no sound, since there were no drivers in /lib/modules at
all. I am puzzled even at how the system managed to boot ...
Another problem prior to that, was the X11 upstart. Due to this I could not get
XFCE loading completely, so all I kept seeeing was an empty screen with the
mouse moving (slow).
The upstart problem was solved by the upgrade. The drivers problem by running
install-grub from the live CD.
All went good. My son tells me this better than the previous version.
You guys are doing a great job.
I would like to contribute, some way, maybe by buying something I guess. Ubuntu
Studio must stay alive.

Yuck. If you don't stick with the LTS's, you need to keep up to date
with the latest release!

Hello list! My son uses and likes Ubuntu Studio for audio/video/gaming.
I am an old Unix die-hard using unix since early SunOS, and also
FreeBSD/Linux since the early 90s.
Ok, enough with the intros, here is the steps that lead to the problem :
At first I tried to upgrade from 16.10 but obviously there was no update
path due to 16.10 being obsolete. Then I tried a hack to force upgrade
directly to artful , by changing /etc/apt/sources.list but this resulted
in an unstable system (no grub, ultra slow USB wireless mouse and
keyboard, etc). And finally decided to bite the bullet, back everything
up and go for a fresh installation. In the process of installation I
decided to keep old user data files (i.e. not format).
Files were kept, but not the exact users -> uid , groups -> gid
mappings. So I had to do some editing there.
Everything seemed to go semi-OK, but then started some more problems.
Mouse/Keaybord were still slow, laggy even lossy (keyboard). I changed
the USB port and keyboard and mouse started behaving good.
Then I decided to test some sound. I am not currently on the box, but i
supposed the tool I used was : xfce4-pulseaudio-plugin . This detected
no audio card. Just a dummy card.
Can you guys shed some light on what to do next?
I am afraid that I am not the best person to help out here. There is
some help (although getting dated) here:
You could also try running from a Live DVD, to compare settings etc.
Ralf has also emailed some good troubleshooting commands on this list,
if you search the online archives.
Let us know how you get on.
