From the 105 manual...
Pure Audio ModeYou can enjoy higher quality audio by turning off the video processing and output.
The Pure Audio mode reduces any potential interference between the video and audio signals.
1. Press the PURE AUDIO button on the remote control to turn off video and enter Pure Audio mode. Video output will cease
, the power light will dim and the front panel displays will turn off.
2. Press the PURE AUDIO button again to resume video and cancel Pure Audio mode.
Pure Audio mode is automatically canceled when the unit is switched off or when playback is
stopped.Because HDMI carries audio together with video, the HDMI video signal cannot be completely
turned off. A black screen is transmitted instead to minimize any potential interference.
This seems contradicatory, isn't sending black frames still video output? I use this mode often just to prevent plasma burn in...but have not noticed any audio difference.
