I have linux skype that complains that it can't use sound device without giving any details. 'truss -f' flag doesn't show any system calls related to sound device (/dev/dsp*). Maybe it's because of child processes aren't really monitored by truss for linux processes. But sound from another sound application gets some strange interruption and buzz every time I try to activate sound from skype. That's how I know that skype really does something with sound device. Is there a way to probe program's activity with devices in-kernel? Yuri
