It's from the speakers - it doesn't sound like the single tone that the 'built-in PC speaker' makes. So I guess ALSA is generating it rather than pcspkr.
However, I'm pretty sure it's the 'alert' beep function. I hear the same sound if I'm in console mode (eg if I boot in recovery mode or use ctrl- alt-1) and use the tab key in bash to auto-complete a filename or command. But this is with the pcspkr module *unloaded*. So something has changed in the way the kernel generates this alert beep - in older kernels I used to hear the single tone built-in-pc-speaker sound when I used tab to auto-complete, but if I removed pcspkr I didn't hear it any more. -- PC makes an annoying squawk on selection of restart/shutdown https://bugs.launchpad.net/bugs/329924 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
