virtualbox doesn't play pc speaker sounds generated by the guest

[Gregory Nowak]

When the guest generates sounds via the pc speaker, they aren't played on the host through either the host's pc speaker if one exists, and/or through the host's sound card. I believe that vmware sends pc speaker sounds generated by the guest to the host's pc speaker, and I know that both qemu, as well as virtualpc send pc speaker sounds generated by the guest to the host's sound card. I personally would find it very helpful to hear any pc speaker beeps which the guest generates, and would appreciate it if the inclusion of this feature in virtualbox could please be considered.
