Bug Description
With Ubuntu 9.10 Karmic a "popping" sound is quite frequent on my HP NX7400 along with a short indication by the onboard led that sound is supposed to be muted. This is a regression from Jaunty, where this problem did not occur.
This bug is triggered while using most applications, but can be reproduced especially reliable by:
1. Opening the terminal
2. Pressing tab
No indications to the source of this error is reported in the log files while reproducing the bug.
If an audio file is played while trying to reproduce the bug as described above, no indication of the bug is seen.

I wonder whether it might be something related to sound power saving... I noticed there has been a change in the latest updates adding a "powersave_ controller= N" into /etc/modprobe. d/alsa- base.conf. So first thing would be to see whether the bug is still reproducible with the latest updates (with that controller line in). If it is still there, try changing the powersave value in that file from 10 to 0 (disable powersaving). Then reboot and check the sound again. If it is gone then, we know at least it is related to that.
