Comment 3 for bug 162336

[Hardy 8.04 alpha-1 sound] I just compared my sound settings between my 7.04 and 7.10 installations (where system sounds work) and my 8.04alpha-1 installation (where system sounds don't work). On 7.10, the sound events playback device that works is called "C-Media PCI IEC958". This device "test" works and the system sounds play (both in the test play and in the real system events such as login). On 7.04, the system sounds also work.

On 8.04alpha-1, that same sound events device only produces white noise when I do the test and nothing when I try to play a system sound. The sound events device that produces a tone when I test is called "C-Media PCI DAC/ADC" but it does not play system event sounds when I test them. None of the sound events devices play sound events on my 8.04alpha-1 installation. These installations are all on exactly the same machine, just using different hard drives that I can swap out using removable drive trays or different partitions on the same drive, so there is absolutely the same hardware in all instances. This is a new bug introduced into 8.04 alpha-1.
