I have an odd issue (and I mentioned this in another thread)...
My late 2013 27-inch iMac runs through an audio interface (I do audio editing on this machine). When I play STO, the sound only comes out of one speaker. The interface doesn't even register a dual stereo channel... in other words, the meter on the interface only shows a left channel, not left and right.
Same here using a Speedlink 7.1 USB Headset. No problems on OS X Desktop or Windows via Bootcamp. Must be a Client problem. Hope someone will notice and fix it. Itīs just impossible to use Teamspeak or Skype with game sound turned on cause itīs just on the left side.
Since I am not the only one, I submitted a ticket to the devs... we'll see if that gets us anywhere. I fear that the Mac client team is made up of one guy, LOL... and is only part-time... and barely uses a Mac.
If Mac users continue to notice this problem, then submit a bug report in-game. That is ultimately what I did.
I have a feeling that our Mac user base is small, in the first place, and I fear that the devs have a "Mac guy" that only works weekends... in months that end in "y." So many still think it's 1999, and the Mac isn't worth developing for, game-wise. Frustrating!
Still, if enough of us bring this up... hope springs eternal!
