Hello, everyone. First-time poster. Please be gentle.
Summary: Background audio is loud(er), hissy/choppy on XBMC 12+ compared to XBMC 11 on my Mac Mini. Problem does not occur on my MacBook Air.
The Details
System:
Mid-2010 Mac Mini
2.4 GHz Intel Core 2 Duo,
4 GB 1067 MHz DDR3 RAM,
NVIDIA GeForce 320M 256 MB video at 1920x1080@60 Hz using OpenGL version 2.1 NVIDIA-8.24.15 310.90.9.05f01,
built-in audio at 44100 Hz sample rate,
played through Altec Lansing speakers (I tried the MacBook Air with those speakers and it's not just the speakers, I promise you.)
OS 10.9.4 (Darwin 13.3.0 x86_64, build 13E28)
All XBMC versions installed from .dmg
XBMC versions tried: OK on 11.0, problem on 12.2, 12.3, 13.1, 14.0a2
For this report, the problematic version is XBMC 13.1 tagged 20140604-84725b0
Steps to reproduce:
Play a video on XBMC 11.0 and notice that it sounds fine. Play the same video on XBMC 13.1 and notice that the background audio sounds louder and hissy/choppy, while the foreground audio has a bit of echo.
