How do I "remove" a sound card in Ubuntu.

Capt'n Midnight

where do I remove references to the sound card so it can be detected again ?

lspci etc. picks it up but nothing in the GUI
I can't disable it in the BIOS either , to turn it back on later.

tried running alsaconf?
sudo alasconf

Capt'n Midnight

yip, it don't run
ubuntu breaks alsaconf - I'm trying to pull from a different repository.

tried
dpkg-reconfigure alsa-base
dpkg-reconfigure linux-sound-base

Now I'm working through - http://ubuntuforums.org/showthread.php?t=205449

# aplay -l
**** List of PLAYBACK Hardware Devices ****

lspci -v always been visible

these didn't give the thumbs up quite yet
modprobe snd-ac97-bus
modprobe snd-ac97-coded

* Failure -You have two options

* Move on to Getting the ALSA drivers from a *fresh* kernel. This step is easier and is recommended to users who might have been tinkering with their sound settings and want to revert back to the way it was just after installing Ubuntu (without reinstalling Ubuntu of course )

* Move on to ALSA driver Compilation, if you have not done so already. If you have, please post a new thread with your problem.

in later steps had the GUI go AWOL.

in [edit]sudo [/edit]terminal you get noises when you
aplay /mnt/c/winnt/media/tada.wav

so why is there no default sound card in the GUI

sysinfo 0.6.1 sees it
hardinfo sees it

alsamixergui
alsamixer:function snd_ctl_open failed for default: No such device

Ah !!! I can see the oncoming train :eek:

if I runs it as root I gets controls :rolleyes:

chown'd ( too much sudo bash b4 )

so changed user priviliges (use audio devices) and retesting - works !
system - administration - users and groups

pffffftt - why would anyone want to use an OS that doesn't give everyone full control and start every service

I'm guessing your day to day account is not the one set up during install.

All users who need to use sound devices need to be members of the group 'audio'.
The first user set up during install is set up with this.

There are other groups that you're added to by default as the first user,
and you should probably add your everyday user to all of them.

This command 'grep <OriginalUserName> /etc/group' will show them all.

They'll probably look something like this, and as you can see, a user would have problems not having access to most of these things.

dialout:
cdrom:
floppy:
audio:
video:
plugdev:
users:
lpadmin:
scanner:
admin:
fuse:

You can add the users' names to the file if you're comfortable with an editor, or use

"System -> Administration -> Users and Groups"

I know you've the problem sorted, but it could clarify similar problems
you'll come across soon (scanner for example), and it puts an answer on record for others.
plugdev is an important one :-)

Good luck,

nah, I deleted that one after a few days
who needs root access anyway

more than once I've googled for a fix and found my own post for help
