- Dullie - 2012-02-15 I tested TrueHD track of The Dark Knight and every ten minutes or so I am losing audio and I get this annoying loud static noise, its like my Denon 3808CI AVR is receiving a different signal. So I stop the movie and play again and everything is back to normal ten minutes later it happens again. I am using nVidia GTX 460, and DDDamian build however I am not using the AV delay advanced settings combo. Anyone else experience this? - eskro - 2012-02-15 outstanding work!! thank you DanielaE and DDDamian!! - disco277 - 2012-02-15 Thanks for clarifying Dani! - DDDamian - 2012-02-15 mrhyde1969 Wrote:Since using this version when I pull up OSD I see that something else is being displayed 'ae',which is measured in 'ms' This seems to steadily go up that by the end of a 2hr film its showing as 11.1ms. Can anyone explain what this is please? What you are seeing is the accumulated audio "error" or time-sync loss. Depending on hardware/settings this may accumulate quickly and reset as XBMC keeps the sync. I'm pretty sure based on what you report that you had "Adjust display refresh to match video" enabled - and if you're sure that the value didn't reset often during your watching then you can be happy that your 520gt is keeping quite close to the actual video rate Dullie Wrote:I tested TrueHD track of The Dark Knight and every ten minutes or so I am losing audio and I get this annoying loud static noise, its like my Denon 3808CI AVR is receiving a different signal.

Make sure your nVidia drivers (including the HDMI audio driver) are the very latest. I believe the nVidia controls allow for some tweaks to the 23.976hz refresh rate that AMD/ATI doesn't, but you'll have to research this. Tune that. Unfortunately the Global AV Delay won't help you here, but the driver update/tweak may help. If not you have to either replace the card, wait for a better solution or try unchecking the TrueHD passthrough and decode to LPCM for TrueHD. This is not such a bad thing (still lossless) unless it's a 24bit TrueHD track. See earlier posts for the whole 16bit/24bit thing. - DDDamian - 2012-02-15 eskro Wrote:outstanding work!! thank you DanielaE and DDDamian!! It's Daniela's work of genius - all I can say is how impressed I am at how "surgically" she managed to make this bit of magic happen, and having the talent and *ahem* balls to just roll up her sleeves and do it. Brilliant! - DanielaE - 2012-02-15 And I am pleasantly honoured by your outstanding patience and perseverance guiding people through the pitfalls because of these myriads of hardware and driver combinations - I certainly appreciate that! - mrhyde1969 - 2012-02-15 [quote=DDDamian]What you are seeing is the accumulated audio "error" or time-sync loss.

I dont have Adjust display refresh rate enabled,infact all video settings are standard.I only have "verticle blank sync" enabled - DDDamian - 2012-02-15 mrhyde1969 Wrote:Hi thanks for that.

All good - DDDamian - 2012-02-15 DanielaE Wrote:And I am pleasantly honoured by your outstanding patience and perseverance guiding people through the pitfalls because of these myriads of hardware and driver combinations - I certainly appreciate that! Judging by the "custom speakers" in your sig we both enjoy good audio - voip-ninja - 2012-02-16 okay here is the log output from the true-hd audio drop; also i am using the advanced settings that was provided earlier that does the lip sync fix. i have refresh to display set to on, match framerate to source set to on with audio resample as the clocking method. fullscreen window instead of true fullscreen ON. Code: 19:26:53 T:1792 NOTICE: Creating audio thread - DDDamian - 2012-02-16 Yep, you lost sync alright. BTW, resample is the same as drop/dupe when bitstreaming. You can't "resample" without decoding. Is it still happening if you run true fullscreen as discussed? (Not fullscreen window mode)? If so, for now anyways you may have to decide whether you prefer a video frame drop, audio frame drop or decoding so you can resample. Or get an ATI - voip-ninja - 2012-02-16 I am running true fullscreen mode. What I don't understand is why I don't have this problem with any other audio format. Thanks for taking a look. - bluray - 2012-02-16 voip-ninja Wrote:I am running true fullscreen mode. What I don't understand is why I don't have this problem with any other audio format. Thanks for taking a look.As I said very often, Intel made great CPU but they are behind AMD/Nvidia on GPU. They should have bought Nvidia when they had a chance. Maybe, it's time to spend $35 on HD6450. You'll have more time to enjoy the movie! - DDDamian - 2012-02-16 voip-ninja Wrote:I am running true fullscreen mode.

NP - there's quite a few things that could cause this from a bad bit in the data to a buffer under-run to a background service starting up. Won't be easy to eliminate 100% on all hardware thus the suggestions. |
