BossNoodleKaboodle said:Yup it just messes up the sound. True DSP would sound better but I don't know of a good one other than DFX.
Donnie27 said:"ON" 5.1, Sound Mixer Speaker settings to 5.1.
Flat or "no" EQ, disable any EQ settings.
"NO" CMSS/2 or Etc. CMSS and CMSS 2 are Pro Logic like settings, they disable Discrete 5.1 when they're enabled.

thomase said:That is not all that CMSS does.
Its true that CMSS performs upmix when the source is stereo and you have the Creative Speaker Settings set to 4 or more speakers. The CMSS2 variant adds virtual room acoustics which most people probably want off.
Additionally, if the source is more than 2 channels and the Creative Speaker Settings are headphones or stereo, CMSS virtualizes the multiple channels to playback over headphones or 2-speakers (not unlike Dolby Headphone or Dolby Virtual Speaker). CMSS2 adds virtual room acoustics (again like Dolby Headphone). More importantly, if the sound source is 3D (via Directsound3D for example), CMSS is REQUIRED in order to get proper 3D positioning. You can verify this for yourself by using the Rightmark 3DSound Positioning Accuracy Test. Turn CMSS on and off during the test (while using headphones or stereo speakers) and you'll see what I mean. When CMSS is off, you just get panning from left to right without front/back positioning. Basically, the "Dolby Headphone" like feature and 3D positioning use the same underlying DSP filters which are turned on by enabling CMSS.
Donnie27 said:Last things first, only the Audigy 2 ZS carries this feature but it is worth mentioning. When you switch to the headphone setting, the sound card upmixes any signal to 24bit/96KHz Stereo.
Donnie27 said:The short answer is this, CMSS/2 is the sound card's version of Pro Logic/ PL-2. CMSS 3D is not as good as a clean sorce to me so *I don't use it.
Donnie27 said:Yes, it can add but it can, must stress *CAN, take away from Discrete 5.1, 6.1 separation and etc.. Creative cards have long suffered from using 16bit sound effects. This is why these setting will many times just disable themselves and do nothing. DVD Audio and DVD playback, recorded to the HDD 24bit/96KHz sounds and music, yes, I have such recordings and etc. will not even react to these setting changes. When they do, they're negative.
Donnie27 said:These settings can disable better DTS that UT2K 3 and 4 supports, takes away real rear sounds from other games and adds a pro logic filtered fake rear. Echos and that's about it. I get perfect rear sounds from HL2, Call of Duty UO, PainKiller BOoH, and even Doom3. That's with or without EAX support.
Donnie27 said:If a Game doesn't support EAX 3 or 4, then by all means use CMSS/2 and as you said it will work with DirectX 8.1 or higher to do a good job. Use a game that supports at least EAX3 and the the difference is no contest IMHO! As was said on that other thread, 2Ch headphone can't reproduce 5.1=P
Donnie27 said:Its important to note that CMSS can improve 2Ch a great deal.
Donnie27 said:This does NOTHING for true 5.1 and or 6/7.1 and even DTS plus DTS Neo 6.
Donnie27 said:I tested this by recording via Analog 24bit Hotel California being played by PDVD6 to the Audigy2 ZS on my computer #1. I hit playback and bang---24bit-96KHz perfect sparation. While set to 5.1, CMSS has ZERO affect=P
thomase said:Keep in mind I'm only talking about headphones here.
Upmix means to playback on more channels that the oringal source material. Downmix is playback on less channels than the oringinal source. Downsample means to reduce the sample rate (this effects quailty, max frequence, etc.). So you mean to say that it downmixes AND downsamples to 16bit/48KHz when using CMSS with headphones. I don't know if it downsamples to 16bit/48KHz when NOT using CMSS. It definitly does downmixing to 2-channel panning, but I don't know if this happens in the EMU10K2 or the other chip which handles 24-bit audio. If it goes through the EMU10K2, its downsampled. Any CMSS or EAX effects go through the EMU10K2. However, any game audio samples that I am aware of are recorded at 16bit/48KHz or lower. I agree that you don't want 24bit/96KHz audio going through the EMU10K2, but this is only relevant for DVD music and movies I think. To avoid this, turn off CMSS and EAX effects.
thomase said:Assuming movies are 24-bit, you can arguably get true 24-bit output by connecting the multi-channel jacks to some 5.1 headphones. However, 5.1 headphones suck if you are into sound quality, that defeats the purpose.
thomase said:If you use CMSS to get virtual surround, you're screwed again because it converts to 16-bit.--1
The only remaining option is the Dolby Headphone mode on your software DVD player.--2
This might also convert to 16-bit and downsample but I'm not sure of the details. I don't know if the Dolby Headphone tech specifies a sample rate/size. --3&4
If not, its up to the software developer I guess. Anyway, while watching a movie, if headphones are the only option, I'd rather have virtual surround in 16-bit over good headphones than 24-bit surround with shitty 5.1 headphones==5
thomase said:I'm not aware of any game that outputs DTS during gameplay. Soundstorm encoded DD for games, but then we are not talking about the Audigy 2 anymore.... Anyway, you shouldn't be using CMSS when playing games with 3D sound IF you have multi-channel speakers. BUT if you are using stereo headphones, you MUST enable CMSS to get proper 3D sound in games. Sure, DD cutscenes will be downsampled to 16bit/48KHz, but does anyone really care?
thomase said:Yes they can. We only have 2 ears. There are many threads here stating the opposite."
thomase said:If you are using multi-channel speakers, I agree.
SystemERRor said:Im no audio genius, so a lot of that just went over my head.... I have an audigy 2 zs platinum...
if a game has EAX 1, 2, 3 (etc) for the sound provider, i should just pick that, right?
SystemERRor said:I've also been researching into CMSS and CMSS 2 (never enabled them before)....
I use headphones and 2.1 speakers, and play mostly games and some movies/music.
Should CMSS be turned on for virtual surround sound? Or should it only be on at certain tiems? Or should it never be on?
That is pretty much why I gave up.SystemERRor said:hell, that thread just took me a while to read.
Good luck... I can just see them start with the rude comments and name calling all over again.SystemERRor said:Think i got the idea, was gonna register there and double check...
Depends on the game.SystemERRor said:1. De-sync settings in the creative speaker settings w/ the control panel.
SystemERRor said:2. Set the speaker settings to headphones and any game to 5.1
SystemERRor said:3. Turn CMSS 1 on in EAX settings
4. Turning EAX on in games.
Mister X said:That is pretty much why I gave up.
There was no need turning it into more of a flame fest then it was and there was some good stuff there.
Good luck... I can just see them start with the rude comments and name calling all over again.
depends on the game.
For most games you are fine with the control panel sync enabled
I like the 2 speaker setting better but I would suggest you try it both ways and see what you like better.
As far as the game setting goes.
That works with the control panel sync for games like Doom 3......... but again, try it and see what you like best.
Yes and yes
Donnie27 said:1. De-sync settings in the creative speaker settings w/ the control panel.
Sync with Windows but make sure the Sellect Box for "Use only selected device" is chacked. Start->Settings->Control Panel->Sounds and Audio Devices->
Click the Audio Tab and at the bottom put a Chick mark in the box that says "Use only default devices" Click on the Seakers and they will show sync, click on the Advanced Playback Tab and move the slider all the way to the right for the "Best" setting. The same Same for recording.
If you have problems then don't sync.
2. Set the speaker settings to headphones and any game to 5.1
Set the Speakers to match what you're using=P
3. Turn CMSS 1 on in EAX settings
NO EAX or CMSS in Windows, use EAX only on the Game's control Panel.
4. Turning EAX on in games.
Yes
Mister X said:I think what he meant was no EAX effects enabled in the eax console.
Right??
SystemERRor said:What do you mean no CMSS in windows? When it set it in EAX settings it's on everywhere
Oh and BTW according to this, you need CMSS for 3d sound w/ headphones

Mister X said:Did I miss something?
I meant the 3dss thread not anything here.
SystemERRor said:Should i emulate 5.1 speakers w/ my 2.1 too? or is that pushing it?
thomase said:Dude, you are all over the place! I suppose that I am guilty of that as well....
All I'm saying that if you are playing a game, AND you want 3D audio positioning via HRTFs, AND the game doesn't have some built-in software feature that does this, AND you have an Audigy 2 (or any Soundblaster since the Live! for that matter), AND you are using stereo headphones, then you need to enable CMSS. It is understood that if the audio quality is greater than 16bit/48KHz, you will give that up. End of story.
thomase said:I'm not debating whether headphones or speakers are better. Similarly, there is no need to rehash the stereo headphone vs. 5.1 headphone argument (its been discussed enough).
The only reason why I replied in the first place was because you stated CMSS does X and implied that is worthless. I am simply pointing out than under certain conditions, CMSS does Y and is certainly NOT worthless.
Dawiseguy said:I find this statement particularly amusing and indicate that you lack the proper knowledge about the basic concepts of 3D sound and human hearing. The shocking truth is that you don't need more than two discrete channels to experience true 3D sound since you only have two ears!------Would you call their groundbreaking work "simulated" compared to Creative's (and other IHV/ISV) crappy speaker algorithms?
"NO" CMSS/2 or Etc. CMSS and CMSS 2 are Pro Logic like settings, they disable Discrete 5.1 when they're enabled.
3D Spatialization and Virtualization is what the heck Pro Logic 1 and 2 uses, in other words Delay and Panning to try and trick your ear into delpth, environment sounds and echos or the lack there of.
