#59 Changing volume (gain) does not work

[Ros N.]

When I set Audio Output AAC (Faac), in Filters I change Gain mode to "Manual (dB)" and Gain value to 10, converted video has the same volume as source video.

Fault in version 2.6.12 Win 64b and previous versions.
Also tested with versilon 2.6.8 Win 64b and with some version under Ubuntu 14.4

Tested with output: AAC (Faac), AAC (lav), AC3 (Aften), MP3 (lame).
Tested with output format: MP4 muxer, AVI muxer.

Source file example is in attachment JO_cut.mp4.
Destination file is in attachment JO_cut+10dB_AAC_Faac.mp4.
