Play two sound waves through two different sound cards at the same time?

Hi all.

With the help of old ship poles and the example of screw provided with Labview 2009 SP1, I could get a part of the path.

The goal is to simultaneously play two .wav files, to two different sound cards. So far:

(1) I can play a wav file for each sound card

(2) I can generate two sinusoidal waves of different tones and put each two cards separately at the same time.

But when I replace these two tones of #2 with .wav files, wave files play in turn. If wav_1 plays sound_card_1, THEN wav_2 plays sound_card_2, not simultaneously.

It is even possible to play 2 wav files simultaneously on different maps?

I've included a VI of the attempt to #2 above. WARNING: my labview skills are minimal and this vi was very experimental is probably terrible form.

Why do you want to do this. Many modern sound cards have 5 channals output

  • Why I have two different execution plans for the same query on two different servers

    Hello everyone.

    I need your help to solve the problem quickly.

    In a nutshell, we have two servers that have the same version of Oracle RDBMS (11.2.0.4 EE). One of them for purposes of development and another is a production one.

    We have therefore two different execution plans for the same query executed on both servers. The only case of execution is OK and another is too slow.

    So I have to slow down the work of query using the same scheme to explain that young.

  • Can I use two cards at the same time on the same computer?

    Hello

    I have two graphics cards, one is integrated, i.e. HD 2500, Intel and the other is dedicated, i.e. Nvidia Geforce GT620. My question is that can I use both at the same time on the same PC. Whenever I try to connect via a VGA cable (per processor) and DVI (via graphic card) at the same time, the screen goes black and when I take off the DVI cable, the screen will return. When I connect the DVI again after log on, there is just the theme of Windows and folders that I opened all get reduced. When I disconnect the DVI cable once again, I opened the folder displays again.
     
    I want to make use of both integrated and dedicated graphics card, I read on the internet that two graphics cards give a performance gain. Also, I'm a gamer. But in time, I bought my PC, I had no knowledge about computers. I want to use two graphics cards. Please tell me a way by which I can use two graphics cards at the same time without the problem described above.

    Yes, you can use two cards graphics, combined to boost performance. But it depends on a condition: the two (or more) cards must be of the same brand. To make it clearer, you can use two or more NVIDIA graphics (thanks to SLI technology) or AMD graphics (with CrossFireX technology, supports up to four graphics card in a single PC).

    But, a mixture of graphics cards of different brand, as NVIDIA and AMD or NVIDIA and Intel or AMD and Intel or NVIDIA, AMD and Intel, can not be used for SLI or CrossFireX.

  • How to get firefox 4 to allow two separate processes run at the same time.

    I'm used to be able to run two separate processes of firefox and so also run two separate user profiles at the same time as well. But I recently moved to firefox 4 and windows 7 and the other, or these two prevents the old method, I used to work. Basically I was running firefox (via 'run' or via an edited shortcut) with the following executable:
    p - profilename - noremote

    And it would launch a separate process that runs under the profile name. Is it possible to do this with firefox 4 and win7?
    I am a developer (web and desktop applications) and it is highly preferable to do so. One of the reasons is that, if one of the processes one falls, the other is fine. Another is to have separate profiles so that addons with leaks of memory, like firebug, can be run in its own process and I can restart when I have to without affecting other processes. I sometimes also need to set the processor affinity so that a process of firefox is not a big eater.
    Any help would be appreciated.

    The correct format for this command is -no-remote

  • How to set up and use two video cards at the same time.

    I have HP Pavilion a6150d desktop under Windows XP SP3 PC. My goal is to be able to use the integrated video card and GeForce 220 video card I just buy at the same time.

    The integrated video card and GeForce video card (connected to the PCI-E) are installed and usable, but the problem is that I think that my computer cannot detect a video at a time card, so I can't use 2 monitors at the same time.  The video only card detects my computer is what I chose as a primer in the BIOS. When you go to the Device Manager display adaptors I can only find an available video card and that's regardless of Setup as primary in the BIOS.

    My GeForce 220 have VGA, DVI and HDMI display connectors, but I don't have that VGA cables. So my only option at the moment is to use my video card GeForce with band single VGA connector and integrated everyone to use my two monitors.

    I hope someone can help me without spending more money...

    "You're not going to be able to use the graphics card integrated Intel and PCIe x 16 graphics card at the same time."

    Thanks Frank, this already answered my question, you help me already by saving my time searching for the fix (since there is NO solution), although it won't save my money I like always your quick response and your support. My monitor is HPw1907 with a DVI connector, so I'll just buy a DVI cable. My other monitor LCD SHARP that have a HDMI and VGA connector so I'll just use the VGA cable in this one.

    So I guess that my simple goal is not achievable using HP Pavilion a6150d. I love HP more than Dell, but it's doable in Dell, so I hope that HP will have way on how to make this thing work in the future.

    How can I have two virus Gabrielle clocked at sametime?

    When I have only a single virus of Gabrielle, I know, this program is Mcafee.

    It is not recommended to run two anti-virus programs at the same time.  It will make the System unstable, crashes, slow performance and so on.  It is better to use a program that you trust on a regular basis and if you want to double check this program, use a parser in line one of the main websites AV.

    You have two activations and no more. If you need to register a third party, you will need to purchase another package. Yes, the installers can be copied to any media that you consider appropriate.

  • How to play stereo mix music and sing in my microphone at the same time?

    Hi guys, need help with Realtek HD audio driver

    I want to play stereo mix music and sing in my microphone at the same time... not for registration but in chat room, say.

    I'm using XP... Toshiba Satellite S4747 laptop
    In the Realtek software "Realtek HD audio input" microphone and two stereo mix... but I can only select one at a time...

    All solutions please thxxxx

    On a different note... a friend of mine using a non-Toshiba laptop with win XP has an older version of the Realtek audio driver and select the mic and stereo mix at the same time... I downloaded this version in my laptop, but still, I can choose only one at a time...

    Check that the audio settings of Windows and don t forget in the Realtek HD audio Manager. You can find it in the control panel.

    I think that your microphone is on Mute check so this.

  • Why can't I order two different photo books in the same order?

    I find costs for scandalous photo books, especially when I can't it be shipped to one country other than my billing address (which means ordering a Christmas gift you send in Sweden, for €10 and then ship it to the USA myself, pay again). This for a book of very simple picture whose aim was more than a Christmas card.

    I if I could save a little by ordering another book at the same time, having delivered them together, but I can't seem to place two elements in the same order - is this really the case?

    I wish I had looked into the front through the pain of the compilation books, or I would never have chosen the Photos to make them.

    Does anyone have a suggestion? Or if you know a way to export all the photos of a project in order to re-do from another site (pdf export and print would not give enough quality, I guess?)

    Thank you

    Why - because this isn't how it works

    and here, users have no control over the decisions of apple that you do – every project is a separate order with separate shipping

    You can try websites - Photos presto claims to be albut printing from a PDF Preview - Preview a print project in Photos, iPhoto or Aperture to avoid problems - Apple Support - I've never used only read them about them online

  • I have two versions of firefox at the same time?

    Hello

    Probably a stupid question but I have two versions of Firefox on my system at the same time?

    The reason is add-ons that are not compatible with v4. I wish I could close v4 when I need to use an Add On v3.

    Thank you.

    You can install both, but there are a few steps to take.

    When you install Firefox 4, use the custom installation option and choose a different location to install Firefox.

    In order to use both versions, you must create a new profile for Firefox 4 (Firefox stores the user data in the profile). Using the same profile with different versions can cause problems. Once you create a new profile, you can copy some data such as bookmarks and passwords between them. You can also use Firefox Sync to keep synchronized profiles. Finally, you will need to implement shortcuts to launch the right profile for each version.

  • Can I have several pst files open while Outlook is running? I want to have TWO OPEN pst files at the same time. What to do please? As always, thank you

    Ideas:

    • You have problems with programs
    • Error messages
    • Recent changes to your computer
    • What you have already tried to solve the problem

    Remember - this is a public forum so never post private information such as numbers of mail or telephone!

    I also always wanted something similar, but rather an Outlook that manages multiple profiles , which means that you can check emails, calendars, etc., which exist in separate profiles with only an Outlook application running. For the moment, I have to close Outlook to open a different profile.

    As it is, you can have two instances of Outlook running at the same time, which means that cannot open two independent pst files simultaneously. When you start Outlook, it will always check if another instance of Outlook is still running and happening rather than open a new instance. You can programmatically thwart Outlook in finding that there is no other instance of itself (when it is in fact) and do what you think (in this sense the answer is not impossible), but is not an approved approach and you have trouble of programming or run another application - the end result is messy. Runs also two instances of Outlook can put pressure on resources unnecessarily, especially on memory.

    Perhaps what is required is a feature to Microsoft for Outlook request that can manage multiple profiles simultaneously. If you run this I would sign of course. I'm sure that there is a lot more there.

    I hope this helps.

  • Two virtual machines running at the same time

    Fussion 1.0, I remember being able to use two virtual machines at the same time, and each me each own IP without worrying if I used the bridged network configuration or address NAT. With the Version 2.0.1 (128865), only one will get an IP address and the other, the two XP SP3, visit account disabled NETWORK card. Any recommendations?

    Yes, it's tru, but I updated the vmx file to have another MAC. NIC I get this error when I try to boot the secondary machine (which otherwise boots fine solo).

    As I mentioned in the linked post, there are several unique identifiers that MAC address. Fusion has a UUID, and Windows has a SID. All must be unique (my guess is that it's the SID).

    The network bridge on/dev/vmnet0 of the device does not work.

    Which will result in network bridge does not work. The only suggestion I have right now is to try to restart the host, but demand around other people seem to be seeing this as well.
