Hello, For some reason my internal modem is not making any sound (dialup handshaking sounds). The modem sound button is *on* - in the network modem preferences settings. I can still connect to the internet on dial-up so the modem is working.. I just hate it when something is not working even if it doesnt make any difference. It has worked in the past, but for some reason no longer. I have had this powerbook for approx 2 weeks -- maybe an update has corrupted a config file somewhere? i had to trash the help config file for itunes because none of the help links in the itunes help were working, and after i trashed the config file, it rebuilt a new set and now it works... maybe a similar solution to this?
