I'm playing with my new 770, installed a bunch of stuff, now I'm trying to use the Gtalk built in.

Currently I get no sound when people message me using chat or internet call. When I go to Control Panel > Sounds > Ringtone, any of the default tones I select give a "Unsupported ringing tone format".

So I tried playing them in MPlayer (mplayer /usr/share/sounds/call-ringtone0?.wav) and only 1 of the 3 played (call-ringtone01.wav).

Then I tried using Audio Player, and they all played.

Any ideas?

Cheers
