    DISCLAIMER: This might be a really stupid question... it possibly may even be the wrong forum!

    ..but does anyone know how on earth I can upmix my line-in signal?

    I want to plug our TV into the PC soundcard in the games room.
    Sadly AC3Filter, CMSS and a few others only upmix system sounds. All Line-In source is stereo.

    I'm using a Audigy2 (with SPDIF model) via Line-in
    My Wii (RCA), PC (VGA and HDMI) and cable box (SCART) connect to the LCD.

    I'm simply connecting the TV's headphone to the Audigy's Line-In. Sounds great -but only in Stereo.
    I have an upmix button on our G500 Pro Gamer speaker remote -but it just sounds too spatial for TV.

    If anyone can help us get better ProLogic through Line-In it would be great.
    I've been searching all day and quite frankly - I must suck at Google.

    Does your Audigy 2 not have CMSS upmix routines? Cannot use these?

    indeed, just use CMSS. Put it to CMSS or CMSS2 or Surround sound Setting.

    Strangely CMSS isn't applied to Line-In. Audigy2 only has options for CMSS at the moment, with latest official drivers

    It's plainly working for MP3 etc but the actual Line-In is pure stereo PCM. I don't think the CMSS decodes that. :(

    ...so of course I tried kX Project drivers.
    Result: the line-in upmixes instantly with surrounder!

    I'd prefer to use a sEAX'y Creative option though...

    Heh! Thanks for the help -but that's my blog. :thumbup:
    I've tested all drivers I have. Official Creative ones, XP ones, daniel_k ones and so far it's only kX Project that can upmix line-in.

    I really don't want to use XP for this installation -or kX
    kX is really good for music and movies -but I can't get it to sound right for games.

    I thought CMSS would upmix anything, but it appears I was wrong.

    No the CMSS 2 only appears with earlier drivers - but still doesn't affect the line-in source.

    Thanks roguesn1per, if anyone could test their line-in that would be great!
    It might be a new sound card to the rescue. The onboard Realtek I have is the same.

    So if anyone is upmixing their Line-In please tell me!
    I'm not recording, which I suspect would work. I just want to route stereo source to play through the PC's 5.1

    Maybe I have a use for that X-Fi Entertainment mode after all....

    Have you tried the "Crystalizer" mod for Audigy??

    What Speakers do you have??

    my z_5500s let me choose wether to emulate surround with a stereo source

    Crystalizer is good, but if you listen carefully - the volume levels vary considerably. Besides, the same thing applies; it doesn't affect the Line-In. Crazy I know.

    I have Creative Gigaworks G500 Pro Gamer - plenty good enough for the room in question!
    I really don't want to buy an AV amp and speakers unless I can really help it.

    The upmix button on the Creative remote is ghastly for Wii and TV. My Wii and TV signals are in ProLogic -Why does it have to be so hard to use them on Line-In?

    So far the kX has achieved great results, Proper surround of the Mario Karts behind etc -but for PC gaming it's quite terrible if you're the type that relies on EAX 3D positional sound for gaming.

    I'm also quite surprised that nobody else uses their Line-In this way. :S

    So far google has revealed several solutions. Firstly D A/V ID claims that Hardware sound is required. So it could be a Vista thing?
    Dolby Pro Logic is not an encoding scheme like Dolby Digital. Dolby Pro Logic merely takes a source and matrixes it across 5.1 or 7.1 channels. Your Mac or PC's sound card may have software that can do this or the Audio/Video program you are using might have that capability. It would be a software thing unless you have a sound card that has hardware support for it like the ASUS Xonar or some of the Creative Labs sound blasters. ​
    Secondly, over at driverheaven some guy also has encountered problems with the A2 and Line-In. He also found kX Project was the only capable software.

    I'm wondering if this affects all sound cards?

    That is faulty information. ASUS Xonar has ZERO hardware support for anything. Nothing.
    Your right though it does sounds like a "Vista" thing... When using CMSS is Vista doesn't it allow you to specifiy which "source" the effect is being applied to? SHould be right in the same panel. -Might be thinking of the X-fi though.

    Ok thanks. I'll scratch Xonar off the list. I don't really know much about the Xonar. I asked for information, but Asus never responded.

    So now I'm looking at:

    1. Switching to Windows XP (ugh!)
    2. Buying a cheap AV amp and speaker set.
    3. Finding a sound card which will allow some sort of Line-In upmix (or SPDIF-in upmix)

    I'm just amazed such a simple task should require such effort!
    It's only "background" sound decoding, after all.

    DDTS-100

    ..but of course they don't make it anymore.... :3eyes:

    Your also talking about a fairly old card. The Audigy 2 is quite dated now and was never built for Vista. Maybe it is time to find a new card as you suggested.

    I'd buy a Prelude right now if I knew for certain the Line-In would be processed!
    I don't want to spend out all that money, only to find it has stereo source again. :p

    I will check for you and let you know. I run both XP and Vista so I have to boot up and run some tests. I will get back to you about this..

    I ran tests in both XP X32 and Vista X32 and upmix from the Line-in works perfect.
    I connected a MP3 Player to my line in on the Prelude and upmixed 2.0 stereo signal to 5.1 mode. So your good to go with the Prelude.

    No Problem. The Prelude have come down alot in price and they sound awsome stock and even better upgrade. They will do what you want though. Good luck with the Mrs!
