OS: Windows 7
Graphics: XFX Core Edition FX-785A-ZNL4 Radeon HD 7850

Receiver: PIONEER VSX-1121-K
TV: Panasonic VIERA TC-P60ST30

Everything works fine and the audio formats seem ok (see list below), but when I switch the input on the receiver from the HTPC to the cablebox and back to HTPC, I lose audio on XBMC. If I close XBMC and restart, the audio will work again, but it is becoming more and more painful since XBMC hangs up. Kids don't know how to use teamviewer to kill it and restart it. I tried following the guide to merge the ini file using moninfo and it appears to be in override, but it always seems to break when I switch inputs.

Available formats:
DTS Audio
Dolby Digital Plus
DTS-HD
Dolby TrueHD
Dolby Digital

Any help would be very much appreciated.

I confirmed today that the year old problem was a result of power saving settings on the HTPC biggrin.gif... All is good now. Thanks!

With WMP or WMC setup is trickier. Try Shark Codec Pack for that.

Hi Tulli,

Tried it with MPC and it worked perfectly straight up. What a difference! Now just to get win 7 setup on my HTPC and move my work station back to my study.

Thanks for your help. Now I can sleep again.

Guys, my apologies if this isn't a good place to post this, but Tulli you seem like a true mr. fixit.

TV: Panasonic 55GT30
AVR: Denon 2808
GPU: AMD 6570

This GPU is installed in my server/HTPC. Since I use this computer as my file server, I have it set up to stay powered on all the time. My activities button on my Harmony remote ignores the PC when powering off, so it just shuts down the TV and AVR. When I turn the AVR and TV back on, I have no sound from the PC at all, but video works fine. To fix it, I have to power cycle the AVR every time and sound will immediately be working again. Everything is connected via HDMI.

What is going on here? It is driving my wife nuts, and ruining WAF big time.

I did have some issues with AMD's HDMI driver on this PC. One day, I swear it was just gone from my PC. I had to do a lot of uninstall/reinstall of the whole Catalyst suite before it was working properly. Also, I didn't have this issue at all for a while. One day, this problem just sort of popped up and has been ongoing since.

Any suggestions?

There's this free fix (blocking pin 19 on the HDMI connector).

Or a device like the Gefen HDMI Detective (expensive) that will keep the HDMI connection alive regardless of switching.

Thank you so much, trying this when I get home.

It's the Gefen, Dr. HDMI or a similar device then.

Has anyone had problems after updating to windows 8.1? After the update I had to reinstall the edid, and it worked, but now two days later I get no sound over hdmi. Any idea's ?

Should be a driver problem. Did you reinstall de graphic driver?
post #3672 of 3937
I updated the drivers, and it worked but then starrted crakling and disstorting, and then stopped altogether. I think it's a handshake problem, when I switch between monitor and TV.
It's back on now, I will report back if it happens again.

I used the Gefen HDMI Detective and it really does a great job eliminating EDID issues, it is expensive but worth every penny. My entire family uses the HTPC and for the longest time it was a total mess, having to reboot the PC once it got too confused, long blank screens while something was happening and switching away and back the HTPC was about 75% assured to lead to a reboot. We also had to power everything on in the exact right order. Now basically nothing matter, Switch away from the HTPC to the STB and later go back, no issues, changing channels in WMC from HD to SD, no issues, and no more power on games.

The down side is the box will set you back about 100 bucks if you buy it on Amazon, but as I said, it was a deal at that price once I put it in.

Of course you need to replace the TV audio block with the modded one (maybe the Speakers Allocation Block too), update the Detailed Timing Begin Offset (byte 3, or 2 counting from 0) and fix the Extension block checksum (use Vladd's EDID Editor, or Moninfo, which I think fixes it too now, but I'm not sure). That's the complete mod (which is a merge of the modded AVR Audio block into the TV EDID).
I also change the Vendor/Product Identification descriptor and the Monitor Descriptor in the Base Block to the AVR EDID corresponding values. But this is not required for the EDID override to work.

Sorry...can't seem to recollect...what was the reason to replace the TV audio block and update the Detailed Timing Begin Offset?

Well, if you start with the TV EDID as the basis for the merge you only need to replace the audio and speakers descriptors and fix the offset in the extension block (because the audio descriptor of the AVR is longer than the TV's). You also need to fix the checksum.

"TV EDID"... you mean as with the connection chain below?
HTPC--HDMI-->TV (no AVR in between)

Ok.
So when HTPC is directly connected to TV, replacing the TV audio block and updating the detailed timing begin offset is for some other purpose, (not for bitstreaming issue).

That was meant to produce a merged EDID with the full, and fixed, audio block of the AVR to allow bitstreaming for AMD cards and 5.1 AVRs, based on the TV native EDID, which has of course an audio block with limited capabilities. AMD drivers still have this bug with bistreaming with 5.1 AVRs, hence requiring this "fix" (changing the audio descriptor from 6 to 8 channels).

Hi Everybody,

Is there any chance that you can help with my setup. I would Like to play movies with bitstreamed DTS-HD on XMBC. Here is my SETUP.

OS: Windows 7 SP1
Graphics: ATI RADEON MOBILITY HD 4650

Receiver: ONKYO TX NR 1010
TV: SAMSUNg UE55C7000

     When I check the audio formats in audio properties, I can't see any HD formats with the ATI OUTPUT HDMI Drivers, I've tried the Realtek drivers for testing and when I check audio formats, I can see HD formats( so the radeon hd4650 is compatible with HD Tracks ? ). Unfortunatly, Realtek drivers are not compatible with WASAPI output in XMBC. I've reinstalled the ATI HDMI OUTPUT Drivers but when I go back to audio properties HD formats are not here. I think it was a EDID issue.

     So i've tryed differents Edid overrides provided on this site and also tried my own Edid made with moninfo but i have still no luck, in the audio properties, can't see HD formats. I tried to disable pass trough on my onkyo but it still always the same. Can someone help me please ?, i don't know what I can do to make it work.

Available formats:
DTS Audio
Dolby Digital Plus
Dolby Digital

 

Would Like :

DTS-HD
Dolby TrueHD

DTS Audio

Dolby Digital Plus
Dolby Digital

 


Any help would be very much appreciated.

Thank you.

You need at least a Radeon HD series 5 to bitstream TrueHD and DTS-HD.
post #3684 of 3937

thanks for the Answer.

 

I need a 5xxx Radeon even if I can see DTS-HD codec with the realtek drivers ?

post #3685 of 3937

Hello there,

 

I seem to be having two issues when trying to bitstream through my setup:

 

Display adapter - ATI Radeon HD 5990 (Catalyst 13.9 w/ AMD HDMI driver) --> HDMI to TV - Samsung 3D LED UA46D6400 --> HDMI (ARC) to 7.2 channel AVR - Onkyo HT-RC560.

 

1. After using the provided .inf file Samsung LN-S4095D - ONKYO TX-NR906 as the new driver for the SAMSUNG monitor, the number of supported speakers have jumped from 2 to 8 (see attached screenshot). When configuring the speakers as 5.1 or 7.1 at the Sound properties window then testing them (Windows 8.1 x64), only the left and right speakers would yield a sound and the rest (including the subwoofer) would remain silent.

 

I have resetted the AVR, but the same speaker misconfiguration remains.

 

2. When trying to bitstream using the latest MPC-HC with ffdshow (see attached screenshot for configuration tabs), the DTS 5.1 input from an MKV connects to a PCM output and no bitstreaming occurs. The same result would happen if I use LAV Audio.

 

By looking at the Encoded Formats and the Sample Rates with the override installed, you see that the list is pretty full. Without the override in place, only 2 speakers are supported and the Encoded Formats list is empty.

 

Is there a reason to create a custom EDID override with my two .inf files AVR + Samsung? As the supported encoded formats do show TrueHD and DTS etc.

 

I have attached both exported .inf Real-Time Moninfo captures just in case.

 

EDIDs.zip 3k .zip file

 

Thank you for providing the Samsung LN-S4095D - ONKYO TX-NR906 override, before using it, the current setup yielded support for 2 speakers only at the AMD HDMI Output's properties.

 

 

Please advise,

 

Max

You can't bitstream HD audio (I assume your ONKYO can do HD-audio) going through the TV as its bandwidth is only S/PDIF capable (2 channels LPCM or compressed low-res DD or DTS). The connection should be HTPC -> AVR -> TV.

If you just want multichannel DD or DTS a custom EDID override for your TV is required (not the one you used, which is for a non-3D Samsung TV).

EDIT:

Well, by looking at the specs of the Onkyo (here) it can only do S/PDIF audio, so the connection would be OK. I'll post an override that should give full S/PDIF EDID detection for passthrough of compressed DD or DTS (and 2 LPCM) in a moment.

post #3687 of 3937

Thank you for the quick reply.

 

This AVR can do True HD, DD Plus, PLIIz and also DTS-HD Master Audio.

 

When connecting the HTPC to the AVR first and ticking all options under 'Passthrough' on ffdshow, the Output shows that it's 'S/PDIF (1401)' and at the DirectShow Filter's properties, the Connection Media Type is still PCM stereo.

 

 

 

Is this the way it should be?

 

 

Thanks,

 

Max

Could be a splitter problem. Rather use LAV filters (Lav Splitter + Lav Audio set to bitsream). It should work.
post #3689 of 3937

When doing the LAV path, PCM remains:

 

Input - Connection media type: Audio: DTS 48000Hz 6ch 1536kbps

Output - Connection media type: Audio: PCM 48000Hz stereo 1536kbps

 

 

 

Any ideas ?

Are all audio formats (including TrueHD and DTSHD) listed as supported for the HDMI audio device?
