EDID Overrides to solve bitstreaming issues for ATI 5xxx's - Page 124

post #3691 of 3895



For some reason, the PCM issue was there even when I connected the HTPC directly to the TV as well.

Are all audio formats in the LAV Audio Decoder panel set to bitstream? It really looks like the audio stream is being decoded. Are LAV Splitter and Audio decoder being invoked during playback? (Right-click on MPC-HC, Filters)
post #3693 of 3895

Indeed, LAV Audio and LAV Splitter both are being invoked (I blocked Haali Splitter and ffdshow Audio on External Filters).




Should all these ticked options stay as is?




For some reason, the DTS logo light is on at the Onkyo AVR and when I click the Display button on the remote control, I see DTS 5.1 Ch.

Yes they must all be ticked.

What is that "file source" filter in the chain (capture is low-res so I can't tell)? Just for testing use ony LAV filters (no ffdshow) and set the audio output in MPC-HC specifically to the AMD HDMI audio device, like this:

post #3695 of 3895

Hi Tulli,


So I have been trying all over with the External Filters of MPC-HC for a few days, to get rid of the PCM taking over with no success.

It looks like I managed to make MPC-HC stream DTS 5.1, Dolby Digital 5.1 and DTS-HD-MA to the AVR, as the corresponding light turns on.

That being said, with the PCM still taking over the Pin[IN/OUT] at "AMD HDMI Output (AMD High Definition Audio Device)" and at "LAV Audio Decoder".

Turning the light on for DTS-HD-MA on the AVR took some time, as I had to tick the option "Use DTS-HD Framing for all DTS types" at the 'Audio Settings' tab of LAV.

I must admit that without LAV Audio Decoder, no DTS-HD-MA could be achieved on my AVR. Again, I am thankful for your guidance here.


As you can see on the screenshot, the filter "AMD HDMI Output" 's Pin[IN] reads 'Audio Input pin (rendered)', does 'rendered' refer to your assumption that the audio stream is being decoded, even though the proper light (DTS, Dolby Digital etc.) turns on at the AVR's end ?

No, that was just a possible cause, but it was a filter problem after all. Nice that you finally nailed it.
post #3697 of 3895

Thanks again Tulli - much appreciated =)


In order to be able to view 3D content, should I use the EDID override file "Samsung 3DTV + ONKYO HT-R548.inf" ? As my Onkyo HT-RC560 receiver is a 7.2 channel AVR.

If the Onkyo is not 3D capable you'll lose HD audio. Your best option would be two separate connections. And as 5xxx AMD cards can only have one active audio stream the Onkyo monitor must be primary (see 1st. post).
post #3699 of 3895

This Onkyo is 3D/4K passthrough capable. What would you recommend other than going through the 2 separate connections path?

No need of an EDID override then (nor separate connections).

i bought an denon avr-x1000 a month ago.


when i try to play dts-hd ma i get no sound.


i think the lg tv is the problem.  when i connect an other tv the denon can play dts-hd without a problem.


so i think there is an handshake problem.


i played with meminfo but could not solved the problem (i think i doing something wrong)


can someone make a good edid for me please.




post #3702 of 3895
Thread Starter 
The audio descriptors of the LG and Denon AVR are identical. This means that the DENON is incorrectly set to passthrough the TV audio. You need therefore to the set HDMI on the DENON to non-passthrough of TV audio (in my old DENON I set it to "AMP").
post #3703 of 3895

tx Tulli,


I did what you said but i don t get dts hd with the lg tv  with my small hp monitor the denon plays perfect dts hd


I think i did something wrong with the previous edid from the avr can you please have an other look at this edid's.


sorry for my bad english.

Can you please check the supported formats listed for the HDMI audio device (post the print screen if you like - of course connect the TV through the DENON)? All audio formats should be listed. If 2 channels and only Dolby Digital is listed there's a problem with the DENON HDMI setup. An EDID override won't help in this case.
post #3705 of 3895


I tested also different startups   when i first start up the htpc then the denon avr and then the lg tv sometimes i get dts-hd listed but not always.


the connection is tv => denon => htpc


not all audio formats are listed with the lg tv.


when i put the denon + htpc on my hp monitor all formats are listed.and playing.

That's odd. Only DD+ showing up usually means a resolution problem (non-standard HDTV, thus HD audio gets disabled). Anyway see if the EDID override helps:

post #3707 of 3895

I did the edid override and still only dolby digital, dolby digital plus, dts is showing


I hope you got an other sollution to test that maybe will solve tthe problem.


if it is a resolution prolem is there a sollution for?


thanks for all the help.

(Assuming of course that resolution of the LG is HDTV standard - 1080p/i or 720p) I would suggest swapping HDMI cables or connecting to a different HDMI port on the DENON. If it still doesn't work use separate connections with a DVI-HDMI adapter (if AMD it must be propietary or make sure to connect the HDMI port to the AVR). If the graphic adapter is AMD you might need to set the AVR monitor as primary to get sound.
post #3709 of 3895
Hi Tulli,

I have a Win7 x64 running an ATI 5770 to an Onkyo 1010. A while after I turn off the TV and receiver the ATI loses handshake and a box will show up saying a HDMI-to-DVI connector is connected, or something like that. From this point on I'm only able to output stereo from the PC.

A reboot brings back bitstreaming and everything is fine, until again, I turn off the TV and receiver.

I tried a ton of different ATI drivers, tried removing catalyst HDMI audio driver and replacing it with the realtek hdmi driver to no avail.

I also have auto detection disabled in catalyst control panel.

Is there anything that can be done?

Gotcha. Do you know if this is an issue with Nvidia or Intel as well? or this is by-design regardless of the card?
post #3712 of 3895

It's a general issue with the HDMI interface.
post #3713 of 3895
Everyone, I think we have a solid solution in our hands.

I'd like to thank Ryan for his tip here!

This is my situation:

Win7 connected via HDMI from an ATI 5770 to an Onkyo 1010 AVR to the TV. As soon as I turn off the AVR and TV (HTPC running 24/7), I'd lose bitstreaming, Windows will revert to 2.0, and there was no way to change that. Only thing that would help was a reboot, so every time we wanted to watch a movie, or I wanted to listen to multi-channel FLAC via WinAMP I had to reboot the machine.

Ryan suggested I try applying the monitor driver trick in post #12, and that seems to resolve the issue. Right now I'm at work and HTPC is running with AVR and TV turned off, Windows still shows all audio formats supported by the AVR as well as allow 2, 4, 6, or 8 channels LPCM through the Windows mixer.

When I get home tonight I'll pop in a movie w/o rebooting and see if bitstreaming works.

I've removed the Realtek ATI HDMI Audio driver which people said solves the audio issue (it never did help), and now i'm running the original ATI HDMI Audio driver from Catalyst 13.11 beta.

EDIT: Regarding the resolution/icons issues, I've never experienced these, it was always just the audio getting messed up.

That could work (to apply the EDID Override to the GenericPnP monitor driver automatically generated by windows due to HDMI hotplug detection - when switching - giving 2 channel audio). I used to suggest this trick before but didn't work in every case.

Hey Tulli, I was the one who suggested this method to him. I researched a little bit and thought to myself that it might be any easy shortcut to actually editing EDIDs. Tried it out a couple of days ago on my setup (Sony TV, Marantz receiver, & AMD 7XXX) and it worked like a charm. Stumbled upon Shpitz's post (who sounded like he was having very similar struggles to mine) so I suggested this method to him. If I had to guess (and it really is a guess) as to why this works for some systems and not others is possibly the components need to be somewhat newish (possibly HDMI 1.4). There seems to be a lot of 2-way communication going on between components such as ARC, HDMI control, HDMI passthrough, and all the HDCP crap. I believe the #1 culprit for me was HDMI passthrough with my setup (wish there was a way to defeat that feature) but that doesn't matter now as the issue seems to be fixed.

I do have a question for you while I have you're attention since you seem to be very active in this thread (great job BTW). Is it me or does "Sony" seem to be the most mentioned problem child in these EDID threads? I see some other brands mentioned here and there but there seems to be a hell of a lot of people with Sony issues (especially displays). Do they not play nicely with others?

The key problem has really been EDID parsing by the drivers, and particularly by AMD. For instance AMD has not fixed yet their problem with detection of HD audio capability with EDIDs with only a 6-LPCM descriptor (5.1 only AVRs). OTOH Sony AVRs do usually have (not sure if they still do) a weird encoding of the audio block (2 audio descriptors, one for plain audio, and one for HD audio) that could affect EDID parsing. Then I've seen problems like with Samsung AVRs where no HD audio descriptors are present in the EDID even when the AVRs are HD audio capable. Other problems - as with projectors - is bad EDID merging by the AVR that has to be fixed with an EDID override.

Now this particular problem with HDMI hotplug detection of HD audio happens in general (AMD, Nvidia or Intel), maybe because its really due to the WIndows OS itself. But perhaps with latest drivers it can always be fixed by applying the EDID override to the wrong GenericPnP EDID generated by WIndows.

For future reference I'll add a note to the first post with a reference to your posted solution.

Hi sorry im back again 2 years later. Still trying to get DTS-HD Master Audio... I have updated my graphics card to a AMD Radeon HD 6550D And I have a LG 47LK450 monitor and using a Samsung HT D5300 bluray/5.1 surround sound. Last time I tried EDID override it did the override but i never got the 6 channel AC-3 and DTS working... The .inf file i have running right now showed both of those in Moninfo but when loaded the file and rebooted it only gave me 2-channel LPCM. Do you have another File suggestion or maybe a custom one for my Monitor? The onnly way I get sound through the blue ray player is if i have HDMI from the PC to the TV then Optical to the 5.1 receiver. I know that you cant get DTS hd master audio through optical, so what is my best option for the best sound with my set up?

Can you please post the native EDID of the Samsung HTD5300? Most probably HD audio is only possible with the built-in blu-ray player, whereas the HDMI-In has only S/PDIF bandwidth.

An EDID override will be necessary anyway for passthrough of compressed multichanel audio (plain DD or DTS). Note also that 2 channels means "2 LPCM", which is the max bandwitdth with S/PDIF. If you already have a modded monitor driver for your setup install it and check that DD (or DTS) is listed as a supported format. Then set your video player to NON-decode mode (direct passthrough) and it will work. IGNORE the 2 channels detection by Windows.
