[App] HDMI 5.1 audio passthrough patch E/F/H (MST only)

[sari]

hello zolechat,

i have successfully applied the patch, thank you guys for the great work!

Because it's already the main and only function of ARC to do passthrough natively, so there's nothing to patch.

I have tried with ARC but it doesn't work (at least natively). Are you sure about the ARC passthrough?

Could you please give me some hints...
My setup is pretty simple

Code: Select all

[AppleTV] -> HDMI1 [SAMSUNG F6500] HDMI2 (ARC) -> Pioneer BCS414

The AppleTV is configured to output AC3 despite what is attached to.

If I play something with the Samsung (e.g. TV or movie through the native player) AC3 is passed through ARC.
If I play something from the AppleTV, no audio is transmitted to the Pioneer Receiver. The TV clearly identifies the incoming stream as AC3, as shown in the Settings-Audio (Dolby Digital is not grayed out).

Thnx

Maybe that's wrong, you shouldn't configure it to output AC3, maybe passthrough, native, PCM or whatever function you have. I can't patch ARC for it to do what it already does. Something's probably wrong in your setup, no idea what, I just know that ARC is buggy unstable crap, maybe the reason why you have issue.
This patch has nothing to do with ARC, and will never have. HDMI to SPDIF passthrough only.

Nevermind for ARC, I am considering switching to a SONOS playbar which connects through Optical

In that configuration it should work fine, shouldn't it?
I'll probably need to patch EDID though...

It should

It seems your TV's EDID already accepts AC3 (Dolby Digital ungreyed) or AppleTV doesn't care about it and forcibly send AC3, so you might need to FakeEDID only if you expect DTS to passthrough as well.

You know what?!?
I've applied the patch and now I have AC3 on ARC as well!!!
Somehow Samsung blocked the AC3 on ARC with the same mechanism...

Well done.
Thanks a lot!!!!

It was obvious to me that you had already tried before asking, but good to know anyway

[axel17]

BTW
despite its working fine, I have a lot of `failed` in the log file

HDMIpassthru.log

Is it normal?

Thnx again

[zoelechat]

Yeah, that's absolutely normal, patch checks E/F/H series functions and use only existing/accurate ones for your TV.
And since exeTV AND exeAPP patching is needed, most functions in one are not in other, so there's even more 'failed' than usual

[axel17]

I am really enjoying the audio passthrough patch

I wonder if there is a way to make it permanent in the TV flash so I can remove the USB drive?
