Package: linux-image-2.6.32-5-686-bigmem Version: 2.6.32+29 Same problem here, after boot the PC speaker does not work (since the upgrade to squeeze). Standard HP Compaq PC with ICH9 chipset. So no exotic hardware, if that matters. The module pcspkr is loaded after boot, but no beep or speaker sound at all. When I manually remove the module and reload it with modprobe the speaker works normal. Regards Uwe
