Thanks. I did not realise that Ekiga could be so intensive on the
sound card. In any case, it is a 5.1 onboard card that ships with a
gaming motherboard (and has killer onboard video as well) so I doubt
that is the issue. But maybe one of the Windows machines has an old
Creative16 card or such. I'll check, thanks.
