I couldnt find anything on the JIRA to match but wanted to post here first incase it is known.
Over the past couple of nights while using spacial voice I have started getting random IM received sounds with no IMs being received...first its sporadic then it ends up being ocnstant where I have coutned the sound going off over 10 times back to back.
So far the only fix I have found is to relog.
It has never happened while using IM voice chat which is what I usually use since usualy its just me and another talking but sometimes on her land others are around and its easie.
Dont know if it matter but I dohave rights to change streams on that land but this started happening weeks after that was given.
http://slurl.com/secondlife/Winterfell%20Illyria/109/179/25 is the TP for that parcel since I can only remember it happening there
