I’ve just used the latest linux Skype beta (22.214.171.124) for a 20 minute call. The lag was incredible! I’ve never heard anything like it. By the end of the call it was around 15-20 seconds, which does defeat the point of an interactive and instant communications medium!
I’d read that this was a problem, but today was the first time I’ve encountered it myself. On a more positive note the ALSA support worked as advertised and changing to using the USB headset was as easy as it is under windows.
One step forward, one step back?
