chmod doesn't work
 
Code:
# chmod 666 /dev/dsp
# ls -al /dev/dsp
lr-xr-xr-x  1 root root 10 2005-02-27 02:04 /dev/dsp -> /dev/sound
No matter what I do, I can't get /dev/dsp to have write permissions. Someone please put me out of my misery, what is going on?

/dev/dsp is a symlink, you will need to modify the permissions on the actual device it's pointing to.

if this is a system using udev, then you can modify the creation rules for it, rather than manually updating it.

Thanks for your reply. My system is not using udev afaik.

I also do have /dev/sound chmoded to 666. But Rhythmbox keeps telling me that it can't write to /dev/dsp, which is why I'm trying to change the permissions for it..

Code:
drw-rw-rw-  1 root audio      0 1969-12-31 17:00 sound

you can't write to /dev/dsp
another device/program actually accesses it and manipulates it's output..........

When you chmod a symlink (as you do) you're really chmodding the file it points to. Try chmod -v 666 /dev/dsp. The -verbose parameter will give you feedback. The symlink mod will remain the same but /dev/sound will have changed.
