Your right about the volume level - I played it in a different media player at the sametime as some music and it wasn't audible with the music at 100%, but was clearly audible at 15%.
What about the way that I only actually get the notification sometimes though? Most of the time it doesn't make a noise at all.

It's annoying, as there are people I need to talk to, but I don't look at the sign-in boxes all the time (in 7.5 I turned them off because of the people who signed in, then again, and again, and again...). I can't trust the sound alerts to work anymore.
