Play stereo mix using digital output?

%With this option in console launcher checked and unchecked, what is the difference for you?
I havent found anything in the documentation, except this plays whatever is coming into your line in jack?
Thanks for shedding light

This enables simultaneous audio out on both the analog and the digital outputs. Found it here:

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

Hi guys, need help regarding Realtek HD audio driver
I want to play stereo mix music and sing in my mic at the same time.... not for recording purposes but in chatroom let's say.
I'm using XP...Toshiba Satellite S4747 laptop
In the Realtek software under " Realtek HD audio input" I have mic and stereo mix both.... but I can only select one at a time.....
Any solutions plzzz thxxxx
On a different note.... a friend of mine whose using one non-Toshiba laptop with win XP has an older version of the Realtek audio driver and can select both mic and stereo mix at the same time... I downloaded that version into my laptop but I still can only select one at a time....

Check the audio settings in Windows and dont forget in Realtek HD audio manager. You can find it in control panel.
I think your microphone is set to mute so check this.

Horrible feedback using digital output SB0

Hi,
I have a Music Xreme SB0460 sound card for my home theater PC to get the digital signal to my A/V center. The card worked fine until I upgrade to Vista and could never get it to work. So I went back and installed XP, but then it updated to XP sp3 and it has been a disaster ever since.
I downloaded the correct driver and installed it, but now when I use the digital output on DVD's, I get this feedback of about second of audio that jsut keeps looping, it changes every few seconds as the DVD plays. If I pause the DVD, the feedback loop continues so whatever is looping at the time of the pause, keeps on going indefinately.
I have turned of all functions of the card in the console, except keeping the SPDIF on at 48k and setting it to external Dolby Digitak and DTS decoders. The Dolby Digital light comes turns on on my reciever so I think the signal is getting through but the computer is generating this feedback loop.
I have played with this for months - with no luck.
I noticed I have 2 consoles - the old style tabbed, and the newer graphic - is it possible I have 2 console apps running at the same time?
Any help would be appreciated.
Thanks

How to use Digital output to turn on sensor for Analog Input?

I am trying to use a digital output to turn on an array of sensors that I then wish to read on 16 analog input lines. I have a 6024E DAQ card. I am planning to take data at 10-20 hz, so not terribly fast, but I will be acquiring for long periods of time (days) so I will be streaming data to disk.
I have a fair bit of experience in Labview basics, but can quickly get out of my depth when I try something new (like this). I have V6.01.
It looks as though the best way might be to do the DO and then a single AI as individual events, then write to disk and continue through the loop. I am puzzled, however, how to keep this cycle on schedule given that I don't know how long it will take to sample 16 channels
, write the data to disk and get back to the starting point... perhaps this is so fast that I don't need to worry about it? The actual timing of the samples (be it 10 or 20 hz) isn't too critical, as long as I can record at what time they were taken... it would be frustrating to find that I was several seconds off after days of data.

Hello,
Thank you for contacting National Instruments.
If you are worried about the time of your acquisition being off, then you should associate each voltage measurement with a timestamp. This will allow you to know the exact time at which the sample was taken and you will never be off. You can use the Get Date/Time in Seconds.vi in our while loop with your AI code so that you can read a sample and read the time. You can than log the voltage value and the timestamp to your file.

Is it save to use digital output as a digital input signal for another channel

Hi all,
I know this is a stupid question, but I do not have other signal generator by hand. So what I want to know is, can I use the digital output signal of my USB-6001 as an input signal for the same device but on other digital port? I did not try out directly because I do not want to burn the device down......
Thanks
Solved!
Go to Solution.

I do loop backs all the time, especially in my test systems as a way of making sure my signal is making it to the UUT pin. I typically throw in a 10k resistor just in case, but I have never had an issue.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

CFP-2220 using digital output for status to another cFP-2220

I have two cfp-2220 that I want to connect with each other using the DIO's of 5V that they have.
The problem that I have is that I don't know the impedance to connect the CFP2220-1 Digital Output 1 to a relay for switching the CFP2220-2 Digital Input 1.
I am using a relay for interfacing the signal. This relay needs 34mA 5V to operate. I am not sure if the CFP2220 would have the needed power to turn the relay on and to close the contact that will operate the CFP2220-2 Digital Input 1. In the user manual of the CFP2220 does not mention anything about it.
Thank you!

Hi ggarza:
Here is the current specification for the digital outputs on the 2220: http://digital.ni.com/public.nsf/allkb/0147137D2442E4A9862572C100758895?OpenDocument. As you can see there, it only supports 3mA, so it would not be possible to use this relay. In addition to this, you should be careful using this outputs, as the manual specifies they are not isolated.

Transmit/Receive Manchester signals using digital output of PCI 6224

How can a manchester signal be transmitted and received using the DIO of the pci 6224 board?
I want to create a NRZ manchester signal on a digital ouput channel and then have the ability to receive and interpret the same type of signal on a digital input channel.
Any assistance would be greatly appreciated.

Hi VJohnson,
You might find this discussion forum post useful.
Looks like LabVIEW does not have Manchester coding/decoding built in, but it should be do able in your VI by replacing every element with the corresponding two elements, and using double the baud rate as your clock rate.

X-Fi Titanium digital output h

Hi,?
I'm using the digital output of my card to output to a Pioneer 5: AV receiver.
I've used this receiver with many things, and have yet to have a problem with it, but for some reason, I can only get audio when I select 'Play Stereo Mix using Digital Output' in the settings - and in this case, it's obviously only stereo, not multi channel. If I don't have this selected, I have no multi-channel audio what-so-ever not even from the front 2 speakers.
Can anyone help?

Is this for games or music? Anyway make sure you have downloaded the latest drivers, there is a brand new set out today. Secondly make sure you have set your sound settings to "speakers" in the vista ( not creative ) sound panel. Finally under the encoder settings make sure you choose dolby digital li've or DTS. I prefer DTS with DTS connect for music as it sounds better than using DDL and CMSS3D which distorts sound.

X-Fi Fatal1ty Headset combined with Stereo Mix (USB)

Ok...here's the issue...
I use the USB version of the X-Fi Fatal1ty Headset, and I love it...except one little issue...
I sometimes vid stream my games to my online radio station's video stream, and when I am using my USB gaming headset, I get no sound output on the video stream. Obviously it needs to use the Stereo Mix, but, of course, the Stereo Mix does not output any sound when the sound is piped to the headset. Is there any way to get the Stereo Mix to output audio even though I'm using the USB headset as my primary sound driver?

I have a similar issue. If I play video with an AC3 track, the audio is only stereo when played from Media Player Classic and Windows Media Player. Playing the video in the PowerDVD works fine though. It's not too annoying to load up all of my ripped movies in PowerDVD, but it would be nice to get MPC and WMP working correctly.

You can't turn on both the speakers and the mic at the same time? Try this.
Dig down through Control Panel > Sound > Playback tab > select the speaker(s) > Properties button > Levels tab. Click the Mic button to unmute it.
If you don't have the Mic button, you're out of luck.

HT5783 My MacBook Pro (Mid-2009) digital output has stopped working. It turns on the red light at the other side of the plug, but fails to connect with my receiver. Output from Airport works fine.

It was working fine until now, and now suddenly, the sound is gone. I've tried PRAM and SMC reset. Nothing works.
Using the same cable with my airport express, through airplay, the sound comes out fine.
It wasn't working when on Mavericks, nor now, on Yosemite.

Hey marcalc,
Thanks for the question. I understand that you are experiencing issues with the digital output of your MacBook Pro. The following resource may provide a solution:
OS X Mavericks: If you can’t hear sound from your speakers
http://support.apple.com/kb/PH13841
If you’re trying to listen through a digital receiver
If you’re using your computer’s digital output port (not available on all computers), choose Apple menu > System Preferences, click Sound, then click Output. Make sure Digital Output is selected.
Make sure your computer is connected to a digital-ready receiver using an optical digital cable, and that your receiver is set up for digital input (see the information that came with your receiver).
Try adjusting the volume on your receiver. You can’t use the computer’s volume controls to adjust the volume while using digital output.
Thanks,
Matt M.

DAQ error on digital output.

I use a MIO-16E board on my Mac G4. Its analog input and analog output work
fine. However, whenever I use digital output, I get a error code -10008,
which means "the group is invalid" (?). This error is generated by "DIO port
Write".
Does anyone know what it really means? Even the examples come with LabVIEW
get the smae error message. Your help is appreciated.

I believe that the default for digital i/o is that they are configured as
inputs. If you didn't use DIO Config to set them as ouputs, that might explain
the error message.

PCI 7342 digital output

I am using PCI 7342 motion controller and UMI7772. There are 6 relays in my system, which are 24Vdc coil voltage and 37mA coil current for each. Can I use digital output on PCI 7342 through UMI7772 to drive these relays?
PCI7342's digital output is 0-5V, 24mA, but through UMI7772, I can get 5-30Vdc, 100mA output. Am I right? I am not sure 100mA is total or for each output.
Thanks for reply.

Don't forget that a relay is basically an inductor and therefore the inrush current can be somewhat higher than the rated current. But I don't think that this might cause problems in this application.
In any case you should connect a breakdown diode in parallel with the relay coil to keep off inducted voltage from the 734x outputs, or some other snubber circuitry.

Sequential Digital Outputs or Counters

I am trying to sequentially flash four digital outputs. I want to run them at a frequency, with 25% duty cycle, one after the other. To be clear, output one on for 25%, output two for 25-50%, output three for 50-75%, output four 75-100%, then repeat. I tried using four counters, but they are not synchronized, so the pulses do not stay sequential. I am using a USB-6143. This seems really basic, but I am a pretty new user.
Thank you -

Assuming you are using the USB-6343 (there is no USB-6143, although there is a PCI variant), you can either run 4 counter output tasks with triggering and appropriate initial delays, or you can use a single digital output task with the appropriate waveform--for example, using lines 0:3 you could generate {1, 2, 4, 8, 1, 2, 4, 8 ...} to get the desired waveform. The frequency of each output would be 1/4 of your sample rate (the sample rate is configurable).
Either method would work, but using digital output seems like a much more straightforward way to go about generating your signals.

Can I do a surround mix in Logic or Soundtrack using the digital output?

I'm wondering if I can make use of my home theater system to do surround mixing, or if I need an interface with discrete outputs.
I'm doing surround composition, so it would work great if I could do my initial stereo mix on my monitors, and then get a good surround mix preview using my home theater setup.
Does Logic or Soundtrack recognize the digital optical out as a 5.1 (or 6) channel output?

Thanks, Rick.
That is actually what I did - create folders and move topics into them. I also created a TOC - for a more streamlined navigation through the online help. (Otherwise, the folder names appear in the navigation, which is 'clunky'.) I suppose the TOC is also used for the creation of PDF output, although I am not sure. Anyway... it works... and I have a topic hierarchy - in my Project 'pod' and TOC.
Much appreciated,
Mary
P.S. Too bad there isn't an easier method of making a topic hierarchy in the Project. This can be accomplished in Flare without the need for extra folders. Oh well...
