Dolby Digital Driver

[Christian Swindler]

Ofcourse optical can deal with more than just stereo... I've been using optical for many years with various setups (either PC -> optical -> sound system directly, or my current setup, which is PC -> HDMI -> TV (set to passthrough) -> optical -> sound system) and it's always been real 5.1 surround sound. And I'm not mixing things up with Pro Logic 2 here. DTS/Dolby has always been my go-to for gaming and of course 99% of games support that...

If that won't do (i.e. you'll get an error message saying that this format isn't supported by your device), re-run the setup and try DS1 instead of PCCE4, but according to the internet, don't try both at the same time. PCCE4 worked for me though.

Noticed the same thing with 6800. About month ago I bought nice 5.1 setup from logitech, and I wasted couple of days to make it work. I have ended up just using 5.1 via jacks without dolby... It only works in netflix.

I was chatting with the AMD support as well. First thing they got back to me with was this. Unfortunately this wasn't helpful at all (besides, my TV doesn't have earc, only arc). Then they said they have no idea, maybe the 6000 series is just too new and I should wait for Microsoft to release an update. Which I find pretty unlikely to be a solution to this problem.

But just so you know. You dont need Dolby Atmos active in the Sound Propertys to Bitstream Dolby Atmos to the Reciver.

Just try it out. Play one of the Atmos Vids in the Dolby Access App. It will say that Atmos is Disabled, but the Reciver will still get Atmos.

Atleast its that way with mine. I use "APO Driver" to enable "Dolby Atmos Speaker System for Gaming" on the HDMI Audio Output so that I get proper, in OS, Stereo to 5.1 Upmix. But this hinders me from Enableing The Atmos Output Format. But the ATMOS LED on my AV Receaver still activates when i play Atmos Content.

What exactly is your setup and how did you hook it up? I would be interested in getting the Apo drivers running and I appreciate your help, but if installing those drivers would still mean it's just a stereo upmix, it wouldn't get me any further. I'm already getting a stereo upmix, but that's no surround sound.

You're right, when I watch the demo videos, my sound system indicates Dolby Digital even though the app says otherwise. I already noticed that. But it doesn't work anywhere outside the DA app. I'm definitely not getting Dolby or DTS when playing games for example. In that case it's Pro Logic 2 only (not only does my sound system say so, but I can also hear it. It's just a stereo upmix). But when I had the 1080 TI, I was getting real DTS everywhere.

That 99% of games output Native Dolby/DTS is just plain wrong. And that Optical can deal with PCM 5.1 is also totaly wrong. You can only Bitstream a Dolby Encoded Signal over Optical. And for that you need a Sound Card that offers the Dolby/DTS Sound Format.

Windows ONLY Outputs PCM if you dont have an APO Installed. It is so since forever.

Yes your Reciver will Show Dolby Digital 5.1 or DTS 5.1 like mine does but thats only the Reciving Processor wich does things like Speaker Virtualisation and other things to the PCM Signal after its recivied.

Windows by default, without any additional Software only Outputs Linear PCM on HDMI.

Support for Dolby Digital needs to be build in and LICENCED by the Developer. Thats the reason almost nobody uses ist.

Uncompressed 5.1 over SPDIF (Optical) is NOT a thing. Dont wast your Time Trying it. If your Soundcard/Motherboard supports the Dolby Digital Output Format, than great. If it does not APO Driver is your only way to use 5.1 over Optical.

I upgraded to Windows 10 last night and I've been having problems with Dolby sound since then, I've reinstalled multiple times and followed all advice I've found on here, but my problems are currently:

Dolby Digital Plus has miraculously started working, though it looks very different to the last time I used it (it used to be a lot smaller and said Home Theater rather than Digital Plus) but its better than nothing.

I'm still having this problem. VN7-591G. Its very annoying because the audio is way too low when dolby is off and I have to keep turning it back on everytime I enter a new youtube video or run a game...

Anyway Im on a V5-552G and I have had these problems before with a clean install of 8.1 and again this week with the upgrade to W10. Let me tell you what worked for me but before we begin just let me say that Dolby Home Theater has always given me problems and will sometimes just turn off and other times the icon in the taskbar would go away or just not respond. Im hoping it's more consistant on W10 though I dont see why it would be.

The only driver that ever worked properly with Dolby was the driver for windows 8 (not 8.1). the new driver on the Acer site for winodws 10 did not work either. So the one Im using and Im listening music to with DHT while writing this is: Audio_Realtek_6.0.1.6878_W8x64_A

6.If you dont get the "Install PCEE" error, restart and you should be able to enjoy dolby (when its not acting up). If you get the error then you may have not followed the instructions properly. Go back to step 1

I think Im rolling back to 8.1 while I still can since Ive had 3 or 4 blue screen crashes already stating different error codes. I think Ill wait unsil they sort stuff out first. Random crashes that make you lose work are nor acceptable. Win8.1 gave me no such trouble.

y si aplico tu logica, que tiene que ver que te quieras regresar a w8.1? por que eso no lo publicas en otro post, bueno en uno dices que w10 es muy bueno y en otro te desdices... creo que es mejor no atender lo que publicas, gracias por los tips de todas maneras, prefiero dejar aqui la comunicacion por que odio ser tan cuadrado, gracias.

Julio, con todo es respeto, no ests aplicando mi lgica porque lo de volver a w8.1 era un comentario mio, un aadido, y no era una pregunta nueva a la cual yo peda ayuda en un hilo sobre un tema distinto que necesitaba solucin. Espero que puedas ver la diferencia. Luego, la gente tiene derecho a cambiar de opinin no? Sobre todo durante el primer mes de usar un producto nuevo cuano es ms lgico que uno vaya formando una idea. No es as? En todo caso yo no me desdigo y creo que has entendido mal, me explico: Yo decia que W10 era muy bueno en encontrar los drivers, no bueno en general. Y lo de volver atrs era por otros motivos (las pantallas azules). No se trata de ser cuadriculado hombre, que yo no lo soy tanto, pero dime tu que pintamos nosotros aqu teniendo sta conversacin en espaol en el foro de los americanos donde la mayora no entiende jaja.

Julio espero que nis consejos te hayan ayudado, seguir los o no es eleccin tuya. Yo solo compartia de mis experiencias y mi tiempo con el objetivo de ayudar a los demas asi que mejor no me pongas a juicio por favor. Y zanjamos el tema por favor que no tiene nada que ver ni con dolby ni con equipos Acer

Being into my gaming, and just as into my films, I like using linux for both. The problem is, there seems to be absolutely no support whatsoever for EAX/5.1 surround/Dolby surround/ whatever for linux.

The sound deamons and progs for linux are called alsa (Advanced Linux Sound Architecture). I have a creative sound card and have fully working and configured 5.1 digital surround sound. Although you are correct in the lack of EAX support (AFAIK).

I'm not sure if it's my soundcard (I've had issues with microphone - it works, i.e. you can hear yourself in the speakers, but I can't actually record anything?? Set various things to 'Capture' etc, no luck), but seeing as all was well in Windows (while ago now, heh) I tend towards thinking it's a software problem.

Hmm tried the Alsa Wiki, edited my .asoundrc, but no luck. I get a clicking sound (in rear speakers) when I adjust 'Surround' volume in alsamixer, so something is alive, but I can't listen to anything on them. It should work tho, even without a 4/5/6 channel file, right? Thats what's implied in the wiki, anyway - splitting a stereo signal and sending it to front and rear speakers.
