Cc: Ticket locked: yes

Description (last modified by JYA)

The aim of this ticket is to simplify the current MythTV Audio configuration while adding extra functionalities.

*It combines earlier ticket (#5900) by "foobum" ; providing upmixing capabilities and 5.1 AC3 re-encoding. The upmixer can be enable/diabled at any time by pressing Ctrl-U.

*Internal volume control (ticket #6279) to work even when audio is output via a digital device (including 'passthru' and upmixed AC-3). When setting the mixer to "software", gives mythtv the capability to control the volume of all content (including AC3 and DTS)

*Simplification of the Setup/General/Audio screen, only presenting the options when they are relevant to the selected speaker configuration.

*Remove settings that aren't relevant anymore or that only created problem (like aggressive soundcard buffer)

*Simplify the stereo/surround configuration. Previously you had to set the number of speakers to stereo in order to get digital multi-channels.

*Various fixes across the board

new_audio-21955 fixes the two remaining problems. 1- Correctly re-order AAC audio when using ffmpeg/FAAC 2- Fix issues when playing mono audio. Under some circumstances (like using digital output) a mono audio track would give you no sound
