Asus G73JH-xx HD Audio output via HDMI how?

Hi

I'm using Power DVD 10 ultra to get my audio bypassed via HDMI to my Denon avr-3808.

I'm getting perfect DTS and Dolby Digital but it's impossible to get the HD audio(DTS-HD master & Dolby True HD) to my receiver.

I'm running everything "stock"

I've read that i must update to catalyst 10.3, and thus go for bios 211, vbios gary and then catalyst 10.8.

Is there another way?
Already tried the Realtek ATI HD audio driver with no result
Since my laptop is not showing any GSOD, etc etc

thx

the driver i have for my hdmi is from realtek and the number is 6.0.1.5992

Bitstreaming works fine for me although I can confess having had some issues getting it working seamlessly. You do not need to update the bios or vbios as I had it working before updating to 211 and have never updated my vbios.

You may need to wipeout the current and reinstall the correct hdmi driver however. And it my require some tweaking from the "configure" button when looking at your sound devices.

Also I am sure you have, but double check that powerdvd is sending completely unprocessed signal. there is a send unprocessed dts dd option and then underneath that is another option that sends completely unprocessed audio.

Hope I helped a bit

 

I might be off, but can't you just go to the bottom right and click on the volume controls and right click -> playback devices -> then Right click inside the box and Enable "Show Disabled Devices" Then from there you can enable HDMI Sound Output or even use SPDIF output. And from there, you can disable your laptop speakers and enable the HDMI or even set it as default

 

yes you can do that...however stock drivers will not bitstream hd audio

 

Well that's what I figured out.
See the attachement after I've update the realtek driver.

So I have to update to latest bios, vbios and ati 10.3> ?!

I mean i'm not even able to passthrough dolby digital or dts anymore after the upgrade of the realtek driver

 

hmmm... all i can see from your pdf is that it is not even trying to use your hdmi for audio. Try making hdmi the default device and then plugging the hdmi in.

You do not need to update the bios, vbios, or catalyst in order to get bitstreaming to work. You just need the correct hdmi audio driver, and it properly configured.

since your driver number is later then mine I'm guessing it will work.

If you can plug it the hdmi in and get it to recognize and switch to it on your playback device page, then highlight your hdmi connection and hit "configure", set it to 5.1 or 7.1 depending on your setup. next next next to complete setup.

Next go back to playback device page and hit properties for your hdmi, go to the "Supported Formats" tab and make sure that all formats are listed including the HD ones.

Let me know where you run into problems along that process and I can try to help figure out where the exact issue lies.

 

That's the problem. After the driver update it says that ATI HiDef audio device is not plugged in. Therefore "configure" is not possible and so setting to default is also not possible. Properties says it all working properly...

A Rolback of the driver doesn't fix this problem....maybe i'll revert to a image 1 week ago

 

Try going here Realtek

and grabbing the "ATI HDMI Audio Device" , in fact uninstall your current driver and then install the one from the link above and let me know how that goes

 

System state is back 1 week.
At least i'm having DTS and DD passthrough again.
And it's all looking good with supported formats
See attachement
But still no HD audio passthrough ?

 

looks like you got it, there should be one more option in the drop down box in your cyberlink player "Non-decoded high definition audio to external device" see attached image.

If that is not there...

 

That's the one that's missing!! What version of Powerdvd do you have?

Mine is 10.0.0.2113.51

 

Start the movie first, then look at the audio properties for the dropdown.

 

I have no option for HDMI audio when an HDMI is plugged in, does that mean there is something wrong of my creative software?

 

Is the option there when you DON'T have HDMI cable plugged in? If not, perhaps you haven't installed the "ATI HDMI Audio" driver...

 

There is no option when i don't have the HDMI plugged in, no. I will look for the ATI HDMI audio driver i guess

I installed the driver and nothing happened, i still have no HDMI audio

Could someone link me to the version of the drivers that would work on the G73?

 

oh sorry, i actually have an older version but it is ultra....dunno if yours is or not, or if that even makes a difference?

 

This one..

 

mine is ultra also....still only SD sound passthrough..nice challenge i have

 

Well i don't get it anymore! First i got at least DD or DTS passthrough and now suddenly when i plug in the hdmi kabel the "ati hdmi audio" keeps not being plugged in.
And so it's not being detected by Powerdvd or whatever.
Audio is only possible through laptop speaker.....
Strange behaviour

 

Part of the solution :Solved?

Powerdvd Ultra 10.xx doesn't passthrough the HD audio signal, but
Total media Theatre 3 works.
Finally dts-hd master passthrough (and Dolby true-HD!).
1 And it's only configurable " with HDMI cable inserted"

2 and use the correct realtek drivers

Thx
