This bug may be the same as bug 237429, but my triggering conditions are different. Like 237429, I get a continuous drumming noise. I am able to reproduce this on both of my Ubuntu machines (running 9.04). Steps to reproduce are:
1. Log in user 1 on a freshly-booted machine
2. Switch to user 2, supplying credentials
3. Switch back to user 1 and log out
4. Note that we have returned to the gdm prompt, but user 2 is still logged in.
5. Enter login and credentials for user 2
6. Note drumming on continuous repeat. The repeat interval is probably a little more than a second. The sound is the same as is used to call attention to the gdm login prompt being available.

Unlike 237429, this does not happen for me every time I switch users. Logging out stops the drumming, and the drumming does not restart on login. It appears to be a problem with the intration between gdm and an already-logged-in session.
