The physical rear are Left Surround back and Right Surround back, these are only available in 7.1 mode (but the Left Surround back is available in 6.1 mode too) In 5.1 setup the side surrounds should be moved slightly to the back of the listening point See this post for more info: http://forum.doom9.org/showthread.ph...97#post1306597

tyvm.... have it correct, these HDAV Deluxe cards have terrible drivers to be honest. Simple 5.1 channel audio has never gone straight to my 5.1 speakers with out some rear channel bleeding.
It doesn't happen with WASAPI though, only directsound. I am still unsure if this is mpc-hc and ffdshow outputting rear side to rear back instead, and this card just "upmixing" that so that I hear out of my rear side channels, or just the HDAV drivers being bad as I originally thought.

Ya... same problems with vista. Mark_A_W has the same problems I believe, with channel upmixing anyways. Simple stereo gets upmixed to 5.1 (thats definitely a driver problem, and can be gotten around for me by disabling the GX function).
My problem is when watching 5.1 content, or 5.1 files in any software like winamp / mpc-hc. In channel tests, the side right can be heard slightly from the side left (like 10% in the side left). Same for side left test, it can be heard slightly in side right..... With WASAPI from reclock, this effect is no longer heard. I just get confused whether my tests (THX Surround Tests) are designed for rear rather than side channels (visually they show side channels (SL and SR) and so I doubt this is the problem), or mpc-hc, or ffdshow or windows, or my drivers are causing the problem. Very hard to diagnose. As I say I can get around it by using WASAPI but still not happy that I can't get proper 5.1 output from channel tests..... Any ideas how to diagnose what the problem is? Thought windows 7 RC would solve it but no luck. Strange thing is that windows and hdav control panel channel tests don't show the problem. Seems to be limited to directsound output from software. EDIT: Looking at ffdshows mixer when playing the thx surround tests, shows BackL and BackR are active, with SideL and SideR not being active...... At least this might indicate its not the drivers.... The mixer shows this with both mpc-hc AND ffdshow being the decoder. This happens with many of my DVD's, all show back L and R active, not Side L and R. ffdshow mixer is set to "3/0/2 - 5 channels" with LFE channels on, everything else off. I think this is incorrect, this seems to assume (by looking at the mixer visually) that 3/0/2 means back L and R should be used. (the opposite to what tetsuo said, as selecting 6 or 7 channels visually enables the side L and R) mpc-hc ac3 decoder settings are set to "3 Front + 2 rear". There is no "3 Front + 2 side". Is this a mistake / omission? Last edited by mark0077; 9th October 2009 at 19:31. |

I've just discovered (in MPC-HC Goth Sync thread) that with Windows 7, Aero caused me judders (when using 50Hz) and audio lags (when using 24Hz) . Reclock and Goth Sync wasn't able to correct this...
So Aero is not that perfect. And it seems without Aero, I have tearing when watching some videos... Tearing I can avoid if I use D3D in MPC. |

any chance of implementing audio/subtitle language preference options (not for DVD but for all the containers) just like in Haali's splitter: eng,jpn etc...?
btw seems like changing playback speed (2x etc) doesn't speedup natively displayed subtitles |

Then get used to software eventually not supporting your OS and developers ignoring your requests to fix things that break on an outdated OS.

Hi, XP does not have any WASAPI layer, only Vista or 7 do
About the new audio renderer, I have a question about how works MPC HC : if I set MPC renderer as default, MPCHC will try to load it but only once. If the media type is refused, it will switch back to directsound renderer. Graphstudio does not have the same behaviour : it will try the first (and same) mediatype (which is basic and lacks of information, which is the reason why the wasapi renderer will refuse it) and it will try others (more detailed) types which will be accepted. Do you know how to fix this ? Otherwise, there is (at least) one bug in it : the memory is not freed correctly. Don't know why I also made some changes : for example the initialization of the service should not be remade in case of reconnection (so in case of change of media type) |
