Hi all, I received my Galaxy Nexus yesterday and I don't seem to be getting any notification sounds. I have gone into a couple of applications (Gmail, Twitter etc.) and the notification sound is set to Default (the default sound set up for notifications is 'Ceti Alpha') but nothing plays when i receive anything...The light pulses at the bottom but thats all. Is this a problem with the Nexus or is it a bug in ICS? Thanks guys.
