If you missed the announcements, Skype has released a new beta version for Linux (1.30). It has a long expected ALSA support, which can solve a whole lot of sound problems. Also, there are now many options in the Sound tab of Configuration menu. It is possible to set your favourite WAV files as notification alerts and even a ringtone. Hopefully, one day there’ll be an option to set per contact ringtones… There are a few other small changes here and there, which might be more imoprtant to you, than they are for me. So, you should check it out yourself too.
