So it is time for another htpc....

voip-ninja Wrote:Daniela, is there any chance you can create a new build based on Beta 3 that also includes the DTS-MA timing fix that is mentioned in post 238?
I'd like to see that, along with the global audio delay patch added as well if possible.
If Daniela isn't available to do maybe Damien will merge it if he gets a chance, and maybe adding in the audio delay fix for 24p movies too would be sweet.

For £178 you can get a HD audio version or you can get the more expensive Asrock 3D ion. But overall if you want DTS-MA you'll need a newer hdmi/chipset htpc.
I've got AMD HD htpcs and 2 ions too. In all fairness, the difference between the MA audio and the core is only very marginal.
I'm running my rig into a 9.2 Paradigm Reference timber matched config with a Denon 4311ci at the helm. I'm also very very fussy and anally set up my htpc with lasers for pin point accuracy, have began acoustically treating my living room (by using secially coated/insulated art work etc) have duel 320w paradigm reference subs and run a non hd audio and hd audio htpcs in that setup (test rig).
The difference I notice on my equipment is minimal, noticeable, but very minimal in all honesty.
Without starting a debate, I think most home cinemas using entry level equipment probably don't /won't notice a jaw dropping result. The guys in the home cinema thread with actual home cinemas will probably feel/notice it most.
There was a double blind test done by Harmen and a another done by some scientists at an audio research facility that also mentioned the differences were inconsistent and even "trained listeners" struggled to decide which was which on a double blind test.
That said, I do love watching my lights turn on, I do like using the best quality I can if it's free and I do like tinkering with my stuff, so for me I'm all for HD audio... However, if it ment buying a new htpc now, I'd probably choose to wait until it was fully complete and Integrated into xbmc before i slapped down cash for such an upgrade... Your not really losing anything by not having it today (IMO).

On the play information (key O), this is DTS HD in 1516kbps like the normal DTS, is it normal or not ? Thank you

dts-ma has a higher bitrate, the codec info shows the bitrate of core. I think it was not updated. Bitrate is only important for lossy compressions. For lossless compression (and LPCM) it is a completely irrelevant and does not tell anything about audio quality. Just ignore it. If you want to make sure, check what your receiver tells you. If it displays dts-ma, you can be sure you got the "real thing".

That's the same card that I just installed. It was $5 cheaper last week. Still a great deal either way. Plus, i already had the latest CCC installed, so it was just plug 'n play for me!

My receiver says dts ma so it's good, thank you

My ears were burning
XBMC Beta 3 + HD-Audio + Global AV Delay
Taken today from master plus DanielaE's HD audio patch + a11599's timing correction and global AV delay, compiled with installer.
You might find it a little zippier too
Good work all.
EDIT: Updated link to latest of DanielaE's patches - improves TrueHD sync and fixes spash screen to reflect HD-Audio version.

I love you Damian <swoon>
This build will see me for a while Fantastic! Absolutely fantastic!
Why will we find it snappier?... What did you do Damian... c'mon, tell us... What the hell did you do Did you add a turbo or a power boost valve or something?

You are a rock star, going to test this out ASAP!
