 > It does change... (Ignore what my speakers can recieve, focus on the
 data being transmitted), When a program is broadcast in 5.1, the audio
 will change from 2.0 to 5.1... MythTV isn't detecting that change...

 Sigh...

 You can only output stereo. Stereo you get.
 Of course what you can play matters. It's all that matters and the only
 thing that matters in this case.

 You need to understand how audio decoding works and how AC3 is designed

 Your system can only handle stereo. So audio is directly decoded as stereo

 Focus on what you listen, and not the bling of what the OSD will show

 If you have a sample or example of where the change from stereo to 5.1 and
 vice versa isn't detected when your audio system can handle 5.1 and not
 just stereo.

 You can the. Reopen another bug, because that one will be. This one isn't.
 It's working as designed
