Just a quick bug I have with the new build, I don't hear any of the new announcements. All the rest of the sound effects seem fine. Is there a setting I'm missing? I am using mint 17 if that makes any difference, it has just been released so might be that rather than PA. Otherwise great new patch, there are a number of other bugs but these have been covered else where.
Please vote on bug #3497 in the bugtracker if you're also affected. (I apparently don't have enough posts to post direct links :/ )
We're aware of the voice notifications not working on Linux. There's an issue with our audio subsystem and Vorbis on Linux, and only the voice notifications use Vorbis. We're working with our partner to get it resolved and as soon as we get the fix we will include it in an upcoming update.
We have gotten a fix for this issue from our partner, and we will most likely be including that in our next update. Thank you for reporting this!
