Sound very choppy in Windows Vista

AFAIK vista does not allow direct access to soundcards through directX anymore.
This means your soundcards DSP won't be used at all.
So they have no (speed) advantage against onboard-soundchips with no DSP.

Another reason to never install Vista.
(I just bought a X-FI because of the DSP...)

That's interesting... so why would anyone want to buy a soundcard at all anymore? OpenTTD uses Windows Multimedia for sound not DirectX so that might be the cause. Crappy Vista only goes the DirectX path and anything else is dropped. A DirectSound sound driver might help (next to the DirectMusic one). If I have time I can have a look at it, but this is really not a high priority.

This time the Asus P5B mainboard comes with a Soundmax soundcard with HD audio.

And how are you going to connect this soundcard to your high-end audio setup? Vista's content protection mechanism only allows protected content to be sent over interfaces that also have content-protection facilities built in. Certainly S/PDIF is not one. And analog outputs hardly provide HD audio...

Quite old, but interesting article:

Same story applies to soundcards and any other hardware you want to connect to your PC.

The main board comes with digital audio out and fiberoptic audio out ports. I am not really using it as this moment as my stereo does not have those inputs.

But this is off-topic.

OpenTTD has problems with Vista, and as of tomorrow people will be buying Vista.

Hmm, i just read there is an OpenAL-Wrapper called "ALchemy"
for x-fi cards under vista,
which redirects DirectSound/Music and EAX-Commands to the OpenAL-driver of the x-fi.

Currently limited to creative x-fi series only.
Somehow funny.
Vistas UAA had the aim to unify the soundcard drivers,
but every manufacturer needs special drivers for their DSPs to get used somehow.

I pity those people then

As i said before - these digital outputs are S/PDIF interfaces, and they are very unlikely to work with protected content as they do not provide content protection.

They surely will. And they surely will be suprised when they find out they are unable to watch their legally owned HD movies in HD quality, because Vista thinks they are thieves. Its gonna be an interesting year for sure...

I wonder ... How long it will be before the crack-teams have released "fixes" for that "problem"? and How long before afore-mentioned "fixes" appear on BitTorrent, ed2k, and the like?

(Quotes because it's obviously not a problem and it obviously doesn't need to be fixed. After all, MS would never release a OS with known bugs, right?)

Frostregen · Post by **Frostregen** » 28 Jan 2007 19:41

Wasn't HDCP cracked some time ago already?

maartena · Post by **maartena** » 28 Jan 2007 20:20

Yeah I doubt its going to be a problem for long. Both BluRay and HD-DVD have been cracked already too.

But again: Offtopic and nothing to do with OpenTTD

goldberg · Post by **goldberg** » 29 Jan 2007 12:09

Thats not the point. I dont want to hack or whatever. This makes me a criminal.

And the problem is not that Vista requires some special features to achieve content protection. The problem is that _everybody_, even those who never used M$ products will have to pay a lot of money because of that. And soon you may face a choice - either you use a M$ certified hardware (and that costs a lot: new hardware, mess with drivers, etc.) or become a criminal.
Remember, all costs are always passed on to customers.

PS. AFAIK AACS has not been cracked yet. (Although it is possible to exploit player and get the keys. But still, it is not a flaw in AACS)

Open up a topic about that in the off-topic forum.

Lets keep this thread to OpenTTD and Windows Vista, not about whether Vista sucks or rulez.

I'm coding a DirectSound driver for OpenTTD, once it's in a usable state I'll give you vista guys a binary to see if it helps anything.

Thank you Darkvater for your (on-topic

) reply, we appreciate it. I will be watching this topic and test the DirectSound driver as soon as you've coded it.

Cheers!

I'll gladly try it. I now have my (legal) Ultimate Edition, and I love Vista so far.

I am actually running the 64bit version of OpenTTD now, but both 32bit and 64bit versions work the same way - choppy.

I'm hoping the directsound driver will fix it

Frostregen · Post by **Frostregen** » 01 Feb 2007 21:37

Hmm, wouldn't be OpenAL the way to go then, instead of DirectSound?
Or am I missing something?

Darkvater · Post by **Darkvater** » 02 Feb 2007 12:08

I haven't had time to finish the directsound driver, but it should work. This is an executable from trunk/ donnu exactly which revision ;p and includes some other changes. So it is only for testing 32bit windows.

In my tests the DirectSound driver consumed more CPU than the win32 driver (running vmware and spamming the 'pause' button to get sounds), but it could be me of course who can't code a proper DirectSound driver ;p.

Tell me how it works, I'll be back next week.

@Frostregen: Donnu about OpenAL but don't you need additional libraries for that?

edwardvdv · Post by **edwardvdv** » 02 Feb 2007 16:01

You're blazing fast!!!

It seems to work perfectly, thanks for your efforts!

I'll be playing all night and post more extensive results in the morning.

Thanks

I am at work at the moment, but I will test it tonight when I get home.

Still going strong

The game is much more fun when played with "unchoppy" sound...
