Hi, Thanks for your reply. I now upgraded from 2.6.28.3, which didn't even have the CONFIG_SND_HDA_INPUT_BEEP option, to 2.6.30.4. The option is unset. However, the beep redirection through the sound card still happens when the module is loaded. Based on Takashi's comments above, it seems that I'm out of luck with this hardware. The only way to avoid becoming deaf is to mute the PC speaker entirely, unload the HDA module and/or buy a sound card which doesn't have this issue.
