Hm, I do remember hearing irritating PC speaker beep during installation, but not after my system was configured. Did you try to rebuild your kernel with CONFIG_SND_HDA_INPUT_BEEP=n and muting the PC speaker in alsamixer? Anyway it seems that this partially fixed in 2.6.31-rc1 (the irritating frequency). -- Roman Kyrylych (Роман Кирилич)
