Enabling Simultanious Analog and Digital Audio Signals

My apple TV runs through a Yamaha receiver. It is hooked up with component video and digital audio cables. I also need to hook analog audio to my receiver so it can play outdoor speakers through zone 2 (which only recognizes analog signals). Zone 2 does not work when I hook both digital and analog cables. Called Yamaha and they said to look for a setting on Apple TV that enables simultanious analog and digital audio signals. Does anyone know if/how this can be done? Or any other way to make the analog zone work without losing digital on the main zone?

AFAIK, the analog audio on the ATV outputs all the time. The audio output setting in the ATV just determines whether the digital output is Dolby or PCM. Try turning off Dolby in the ATV audio settings and see if that makes a difference. If not, the problem is probably elsewhere.

Simultaneous analog and digital waveform read with PXIe-6361 and BNC2120 ?

Hi there,
I am trying to collect both analog and digital signals from a PXIe-6361 linked to a BNC2120, using the attached VI. I am running Labview 2011 64bit. This is the first time I am working with digital input. On the 2120 board, I have the digital input BNC cable connected to User Input 1 and wire between the screw terminal of UserInput 1 and the P0.1 (Digtial I/O) screw terminal.
I have two questions related to this:
1) When I try to run the VI in its current state, I get the following error:
Error -89137 occurred at DAQmx Start Task.vi:3
Possible reason(s): Specified route cannot be satisfied, because it requires resources that are currently in use by another route.
Property: RefClk.Src
Source Device: PXI1Slot2
Source Terminal: PXIe_Clk100
Required Resources in Use by
Task Name: _unnamedTask<6>
Source Device: PXI1Slot2
Source Terminal: None
Destination Device: PXI1Slot2
Destination Terminal: RefClockInternal
Can anyone point me in the right direction for troubleshooting this?
2) I would like to combine my regular waveforms and the digital waveform into one array which would then be written to file. I can't figure out how to combine the two different waveform types...can anyone give me a hint on this?
Thanks for your help,
Claire.

Hi ClaireJ,
Sounds like a reference clock conflict. This KnowledgeBase (KB) talks about this error when using simultaneous sampling. Also, might want to check the device routes in Measurement and Automation Explorer (MAX) as discussed here. Finally, if you are routing your PFI line over a RTSI connection, this error can occur. This KB discusses it.
As to your second question, this post should help.

Airtunes - Analog and Digital output at the same time?

Howdy,
This may seem strange to ask, but can the Airport Express output audio in digital and analog formats at the same time? Is there a strange splitter cable that could do this for me?
I recently learned that most AV receivers with digital inputs cannot output digital sources to their analog zone 2 outputs. The usual work-around is to connect their digital sources to the receiver by both analog and digital cables.
Mikael

I just learned the same thing. Does connecting the digital and analog connections to your reciever work ? Did you connect them to the same source or assign different sources for each? Thanks,

Start by looking around the examples that ship with LabVIEW (if you are
using LabVIEW).
Also look around zone.ni.com for general data acquisition information &
examples. A good site.

MBP video out to TV using DVI - both analog and digital?

I have a Macbook Pro 10.6.4 2008 Model with details are below on graphics card and display options. I am trying two hookups to televisions which may or may not be possible. Can anyone tell me if my DVI output on the macbook pro is capable of delivering an analog signal to my old sony tube tv with component inputs? Second part of my question is do I have the right dvi cable. I purchased a cable with 24 + 5 pin. This cable does not produce a picture on my analog or digital television. Just snow on the analog and no input on the digital. The cable that came with my macbook pro is a DVI to VGA converter and seems to be an 18 + 5 pin plug....with a few pins missing in the middle. Should I buy another cable with the 18 + 5 pin DVI to component or buy a cable to connect the supplied DVI to VGA converter - VGA to component. Please help I'm confused on many fronts.
Thanks

I made an account and am replying to this because i have the exact same computer as you and i was also at best buy at around 3pm wondering the exact same things you were! The DVI port on our MacBooks are different than the standard DVI ports. Freaking weiiiiiiiiiiiiiird! Get out of my head!!!!
I ended up buying a VGA cable and using the converter that came with my MBP because the DVI to VGA cables at Best Buy had a different VGA than what the MBP has.
Our goals were slightly different though, I wanted a cable so i can connect the MBP to my Toshiba 42inch HDTV. VGA works but doesnt support 1080p, only 1024x768, which is not a fullscreen resolution. So i will be returning the VGA cable tomorrow and looking for a VGA to HDMI cable, if that exist.
So, to answer your question, YES, buy a cable that has the same ports as our adapter, or just use the adapter that came with the Macbook.

Simultaneous analog and digital video output?

Does anyone know for sure whether the integrated DVI-I port on a MBP can (or cannot) generate analog (VGA) and digital (DVI-D) signals simultaneously?
P.S.
If you are curious why I am asking this question, it is because I would like to have my MBP displaying (same data) simultaneously on the Apple HD Cinema display (DVI-D) and a VGA projector in my office. And if the MBP can output both signals at the same time (i.e., using all pins on the DVI-I connector), then the following clever DVI-I to DVI-D/VGA splitter would do the trick:
http://www.pccables.com/cgi-bin/orders6.cgi?action=Showitem&partno=01780&rsite=f .01780
I am assuming if this works at all, then the MBP will dumb down to the resolution supported by the VGA projector on the DVI-D output (just as it does for the internal display).
Tx, -CR

Depending on which version of the MBP you have, this may work under Windows. But it does not work under OS X. There has never been driver support for it.

Error Code EF01, Video and Digital Audio Dropping out

To whom it concerns,
A customer of mine is having problems with his Fios DVR. He will be watching TV through his Integra DTR 40.3 receiver, connected via HDMI cable and his picture and audio will just stop. This is always accompanied by a code that displays on the front panel of the DVR which reads EF01. The customer is usually able to restore picture and audio by performing a power cycle on both the AV receiver and the Fios Box.
There have been numerous occasions of this problem occurring. Sometimes it happens quite frequently, (once every 10 min) other times much more infrequently. Also the problems vary in their severety. Sometimes just the digital audio will drop out but the pitcure will remain. Other times the picture and audio will go out and they will damage the HDMi input that the Fios box is connected to, rendering it unusable. We have since repaired the Integra recevier twice. This last repair we haven't had an incident for 3 months, now we are back to losine Audio and Video.
The customer initially had the Fios DVR replaced, but as the incidents kept happening, we tried repairing and replacing the AV receiver. I keep coming back to that error code because I don't know what it means and nobody can explain to me if it has any significance or bearing on the problems we are having.
Does anybody know what the EF01 error code indicates on the Fios DVR? Has anyone had problems similar to the one I am describing, regarding HDMI video/audio loss?
Thanks,
Kelly White

Hey, Jared here.
The EF01 error code means that either the CableCard inside the box isn't getting any signal, or the CableCard isn't sending out any signal. A really efficiant way to see exactly what they problem is, is to take the box to a another location where Fios tv works fine.
There are two possible outcomes:
Either the box doesn't work, and is still displaying the EF01 error code. Than the issue is with that box, and I must be replaced.
The other possibility is that the box works fine. The error code goes away, and the box works perfect. If this is the case, we know it is the coax wires coming from ONT (Optical Network Terminal). And a Service Technician is required to come out and address the issue.

No digital audio signal over SPDIF auido out (MacBook Pro, Snow Leopard)

There is no audio signal over optical cable.
I have a standard toslink cable with a toslink mini-plug adapter for my macbook pro 15 2009 unibody.
The interesting thing is when I boot in Windows side it works fine, I hear sound and I see Dolby Digital or LPCM logo on my receiver, but when I reboot to Mac side then is gone.
Any ideas?

Have you opened up the MIDI audio setup program and checked the configuration there?

Producer consumer with analog and digital inputs and outputs

Hi everyone,
I am working on a control system program for some practical test work. Currently I am working on the data acuisition component of the Labview program. My architecture is produced-consumer loops with a que. My system will have analog inputs, analog outputs, digital inputs and digital outputs. It's not a time critical sytem, but I would like all of the data acquisition to be synchronised. I have attached my program as it is at the moment. I am having trouble getting all of the data into the que since I have two data types. Also, I'm not sure if i've synchronised the four read/write sequences correctly. I would greatly appreciate if somebody could take a look at my program and give me some advice. Thanks in advance.

Robert, the specific error that I get is:
Error -200462 occurred at DAQmx Start Task.vi:6
Possible reason(s):
Generation cannot be started because the output buffer is empty.
Write data before starting a buffered generation. The following actions can empty the buffer: changing the size of the buffer, unreserving a task, setting the Regeneration Mode property, changing the Sample Mode, or configuring retriggering.
Task Name: Heater testing lab digital outputs
This error occurs at the 'DAQmx write.vi' function. I just want to sent one sample per second, for each channel. I would like the producer and consumer loops to each run once every second.
I have attached part of my code with just the data acquisition and writing. Any help would be greatly appreciated.

Is it possible to send and recieve audio signal with AI / AO in NI-6229 which is DAQ board.

I'd like to test MP3 Player.
The procedure is below.
1. Send a audio signal of 1kHz from mp3 file in PC through AO in NI-6229.
2. Record it with MP3 player.
3. Play a recorded audio signal with MP3 player.
4. Recieve the signal through AI in NI-6229 and measure frequency and voltage of the signal.
5. Compare the signal with original signal.
Do you think it is possible?

Hello Blue Sky80,
It is possible to measure audio signals using LabVIEW and Sound an Vibration toolset. Please take a look at this Developer Zone article on Audio measurements using LabVIEW to get more information on this subject.I hope this helps!

Send out analog and digital signal simultaneously ?

Is there any way to send out an analog signal and a digital signal at
the same time? Time is critical in my application. Milisecond delay is
not allowed. I am using a PCI-MIO-16E-4 board and DAQ 6.0.
Any information from you will be deeply appreciated.

Share what you know. Learn what you don't.

You went a little too far. the while loop I was talking about was the one around the digital write. You've now taken the digital write completely out of the loop and closing it. You can't do anything with the digital when the analog in is running. You've also closed the analog write while the analog in is running. The attached is more like what I was talking about.
Even with the diagram cleaned up, it sounds like you still have a problem. I don't know the details of your hardware setup but I would start by looking at the analog signal you are generating and verifying that it is correct to your hardware. It would help if you had a scope to troubleshoot. If the signal is correct to the hardware, then trace it through to the connection to the DAQ's analog input. If it's correct there and you still don't see the signal, then you may have wired up the DAQ incorrectly. You haven't specified the connection type (differential, RSE, etc) and I believe it will default to differential.

New MBP and digital audio

I'm planning to move from a PowerMac G5 to one of the new MBPs so I can do recording at home and on the road. I currently connect an AD - DA converter to the G5's digital in/out ports. How can I do this with the MBP? I notice only one audio in/out on the 13".

Synchronizing analog and digital i/o

We're using LabView 6.0 and a PCI-MIO-16E-4 to run our electrophysiology experiments, and have a moderately tricky set of requirements.
What we have so far: four analog inputs and two analog outputs to monitor and control two recording electrodes. We need tight synchronization (within << 1 msec) between input and output so that we can properly correlate the timing of responses with the timing of stimuli during each presentation (which are no more than a few seconds long). We do this by using the Clock Config AIs to have our output side set the scan clock (via the AO update signal through PFI 5) and the input side use that scan clock. This all works and we're happy with it.
What we need: we'd like to independently control at least 6 (preferably more) stimulator devices. The stimulators look for TTL triggers, so in principle we could use the DIO ports to send those trigger events. The trouble is timing: we want the digital output to be tightly synchronized (again << 1 msec) with the analog i/o and to be able to specify the timing of those events to within 100 usec or so. I've put together a very dumb VI that takes as input an array of (bit pattern,time) pairs, then uses a While loop and Wait to manage that event list and Write to Digital Port to generate the trigger events. Since Wait is only 1 msec precision, and since we don't have a good way to synchronize with the analog i/o, we've got jitter in the trigger events of about 1 msec, which is too big.
One solution to the Wait resolution problem might be pattern i/o, but our board apparently doesn't do that. I have vague ideas about synchronizing the start of the digital and analog by setting the analog output to start on a trigger and having the digital side write that trigger value to start everyone, but in practice I haven't got that working yet. (A possibly related problem: though our scan clock is supposedly running through PFI5, if I hook an oscilliscope to that terminal on our BNC-2090, I don't see anything. I'm probably doing something stupid. Can anyone spot it?)
I'm new to LabView (though an experienced C/C++ programmer) and thus would greatly appreciate any advice or examples people could provide.
Thanks much,
Kevin

You are going to need some additional hardware to fully implement your problem. An interim approach would be to digitize the digital lines along with the analog data so that you at least have a corrolation of your existing data. The more complete solution is to use either a pattern generation board from NI or the DIO-64 board from our company. www.viewpointusa.com. With this board, you can "schedule" a digital pattern at a specific clock tick. resolutions to better than a microsecond are possible. The clock tick could come from the same clock that your are using. The reason your scope may not have seen the clock signal on your current setup is that the pulse is VERY short. your scope settings may not have been set to pick it up.

Acquire Analog and Digital inputs at the same time with 6025E card

I have 6025E DAQ card, all the analog channels are used
up. There are several digital signals, such as flowmeter. Can I acquire both kinds of data at the same time with my 6025E card? Thanks for your help.

I suggest you search the examples that ship with LV
Digital
Find Examples>>>Hardware Input and Output>>>Digital Input and Output>>>8255
for doing each type of I/O seperately.
When you have found two examples. Just try to run the two at the rate use need in your final app.
Post follow-ups Q's here. I am not personally familiar with that deveice so I can not speak from experience.
I would generally expect that if you sample rate is low (i.e. <10Hz) you maybe happy with the results. If you want to run faster or have the PC do something else at the same time, the timing of the signals form the DIO lines may be suspect.
So...
It depends.

I want to sample syncronously an analog and digital channel and write them to file in array.

I have a PCI-MIO-16XE-10. I am using the AI01 and a DI01 to recieve the signals. I am monitoring and switch and want to know when it comes on in relation to my analog signals when I post process the data so it is important that the signals be synced and placed in the data array. The attatched vi gives some idea of what I want to do. Thank you in advance for help concerning this.
