Bug Description

Immediately after the Ubuntu 9.10 upgrade (done 11 November, 2009) the system beep would no longer occur (e.g. in an xterm for inappropriate command line input, nor when the beep utility is used). The system beep was working as expected immediately prior to the upgrade.

A search of tech notices seemed to suggest that the system beep is controlled by the pcspkr module and could be suppressed by entering this module name in the /etc/modprobe.d/blacklist.conf file. When I found this entry - apparently added by the OS upgrade - I commented it out and rebooted the system. However, the system beep is still not enabled. There is probably something else that needs to be done to re-enable the system beep on the internal speaker. Note: The host system does not have external speakers.

The host platform is Intel Core i7 on a Gigabyte EX-58-UD5 main board. The pcspkr is identified at boot time (from dmesg) -

 [ 9.740168] input: PC Speaker as /devices/platform/pcspkr/input/input6

- as is the on-board Intel HDA audio -

[ 16.299763] HDA Intel 0000:00:1b.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22
[ 16.299795] HDA Intel 0000:00:1b.0: setting latency timer to 64
[ 16.489256] hda_codec: Unknown model for ALC889A, trying auto-probe from BIOS...
[ 16.489423] input: HDA Digital PCBeep as /devices/pci0000:00/0000:00:1b.0/input/input6

Advice for re-enabling the system beep on the internal speaker would be appreciated.

Castalia, if I remember correctly, the system-beeps were muted in Karmic to deal with the reactivation of some feature in the latest kernel. For whatever reason, I can not remember, but that kernel code caused the system to beep quite a bit and so it was muted to save people's sanity.

If you check your amixer settings, you should be able to unmute it to see if the beeping issue occurs for you.

Have you checked the settings in System -> Preferences -> Sound? Is this still an issue for you?

I had commented out the blacklist module and ended up removing it do to a posting on the devel-discuss mailing list and still fails to use internal beep. I however get a "bump" sound when internal beep should happen (ping on IRC is one example.)
