Airplay: stream digital and analog simultaneously

Hi,
My future set-up:
Living room (at the moment): AppleTV with digital optical out to receiver.
Kitchen (open, connected to living room): Airport Express with analog out to amplifier (still to buy).
Streaming digital audio always takes a bit longer than analog. Will I be able to stream music from my iPhone to both living room and kitchen at the same time, without my music being out of sync?
Best regards,
Jef

For me Airfoil from Rogue Amoeba works good. Macmini + ATV3 + Airport Express analog. Also from Spotify.
Have to check streaming from IPhone.

Can digital and analog channels be simultaneously accessed

Hi,
Is it possible to simultaneously access digital and analog channels on
a Multifunction DAQ (such as NI-4351) by issuing commands from parallel
threads using LabWindows/CVI (5.5.1)?
John.

Hi JAH,
I have no experiance with this product, so can not give you a definative answer.
The best I can do is to suggest you try it, if it does not work then you most likely can not do what you want.
Also what version of the driver are you using, I have checked the
download page and version 2.1 only works for CVI 6 or higher and LV 7
or higher.

Array of different (digital and analog) values into multigraph

Hello everyone,
So I have an array with a timestamp on the first column, either "off" or "on" string on the second column, and a number value string on another. The columns are based of variables that reads data based on an update rate. My question is, what is the easiest way to separate these values into a digital and analog graphs. This is because the number values are so high that the "off" and "on" signal is being pushed down as the y-axis auto-scales. I'm hoping that I can use a multigraph, but the multigraph puts the data in one graph (since it's one array).
Any suggestions or help is appreciated.

Hi jachy25,
Below is a link to a KnowledgeBase article that goes over how to use stacked plots in LabVIEW.
http://digital.ni.com/public.nsf/allkb/21E8163F259DA2058625703B007511AA
The second link contains a lot of general information on configuring graphs and charts in LabVIEW, and is a useful document to have when configuring plots.

Breakoutbox for Digital and Analog Output

Hallo everybody
i need to design a breakout box with BNC and SMD connectors for Digital and Analog output (the DAQ cards we use are PXI-6723 for analog and PXI 6259 mostly for the digital an fast AO Channels) I am looking for tutorials and info material for that. On what I have to pay attention what would be a good circuit diagramm design and so on.
Maybe you could give me some tips where I can find good Material about that.
Sebastian

Hello Sebastian
first of all I'll need some more information about your intention. What exactly are you going to do? Do you want to connect, or divide signals? (Which signals?)
Maybe if you have a look in the manuals of the cards, you'll get closer to this. Here you can find out the pin assignment of the cards.

Digital and analog in at the same time

Hello Group,
how do I simultaneously and synchonously aquire (read) data from digital and
analogue channels? In the Manual there are just chapters for aquiring one of
both at a time and I also can't see a function in the menu for that.
Thanx
Frank

Frank,
Depending on the DAQ hardware you have you may have issues with simultaneously acquiring data even on your analog channels. Our MIO (Multifunction Input/Output) DAQ cards have one analog to digital converter (ADC) and a multiplexor is used to scan all of the input channels. There will be a slight interchannel delay and you will not have truely simultaneously acquired data (loss of phase will occur). In order to perform true simultaneous acquisition you will need one of our SIO (Simultaneous Input/Output) cards.
Furthermore, our DAQ driver, NI-DAQ, is not multithreaded. Meaning, you have to pay close attention to what calls you make into the DLL, or to what VIs you are using, if LabVIEW is your development environment. For instance, AI_Read is
a blocking call, meaning if you ask for 10 bytes of data it will block all other calls until 10 bytes have been acquired. So even if you write a multithreaded application to perform analog and then digital acquisition you will have to not ask for so much that you will be blocking for great periods of time.
I agree with Ben's comment that one solution would be to pass your digital inputs to an analog input and use a SIO card to simultaneously acquire data. However, depending on what these DIO inputs will be used for this may not be a suitable option for you.

Optical digital and analog audio out

I just purchased a Pavilion 500-214 with IDT High Def Audio CODEC / DTS Sound+
Is it possible to get both opitcal digital audio out and analog (speakers/headphones) out at same time? Stereo amp needs access to both for multizone/source function. I can manually pick one or the other before playback - it is clunky in that when switching audio out devices the active will turn off but one switching to does not always turn on. But i really need both simultaneously active for amp to work properly. I have also found rear speaker jack to be more stubborn during switching than front headphone jack.
This question was solved.

Hi zombi1,
Welcome to the HP Forums!
I have done some research on whether or not one can utilize both digital or analogue audio out at the same time, and unfortunately this is not possible.
Thank you for posting, and Happy Earth Day!

Problem Receiving Digital and Analog Channels- 22LV610U

I have a LCD/DVD combo TV model 22LV610U and had satellite tv for over a year and the tv worked great! After shutting off the satellite, I wanted to only receive the local channels via antenna. I bought a new RadioShack Indoor TV antenna ( to receive basic UHF, VHF and FM radio signals to HDTV and FM HD Radio signals)...
After setting it up, I still only saw snow...I tried setting up the channels through the menu, and was not picking up any signals. I was also unable to view the "DTV Settings" options for Digital Signal...
Do I need a different kind of antenna? I called Toshiba customer service and was told the HDTV antenna would not be compatible, however, ALL channels are now digital and must be received through this kind of antenna...
Help, Im in a pickle Thanks!

If you are using a STB, then you should connect it with an HDMI cable or component cable as you did.
However, you do not need to autoprogram your TV if you are using an HDMI or component or composite or any other indirect connection. That is because the STB is acting as the tuner; it will automatically receive channel information as part of its on-screen graphics. All the HDMI connection is doing is delivering that video feed to your TV.
Therefore, what you need to do is press the "input" button on your TV remote and select HDMI, or component, whatever you are using. Then you control the channels using your STB remote, not your TV remote, which changes the channels on your STB, not your TV. Again, your TV is only receiving the video from your STB, it's not directly changing the channel itself. It's like having a VCR and turning your TV to channel 3 in the old days; you just need to pick up the video.
The reason why, when you tried hooking the TV up directly to the wall with coax is because most FiOS programming is encrypted digital. That is why the STB is needed to "unscramble" the channels and output them to your TV along with all of its on-screen graphics and program guide. Therefore, if you connect coax directly to the TV, the only channels you will receive are local channels (i.e. CBS, NBC, PBS), the ones that Verizon cannot by law encrypt. The reason why some of those channels are "16-2" or "17-214" is because digital broadcasting, as opposed to analog (think the digital transition last summer) uses "sub-channels," which are the -XXX. Verizon can assign whatever number they want to their encrypted programming (i.e. ESPN HD can be 214-1445) because the STB will read that channel and display it within it's own system as Ch. 570.

Z77a GD65 simultaneous audio output via digital and analog jack?

Hi,
Does anyone know if it is possible to use the digital audio spdif out, and the green 3,5mm jack (I use it for my headphones) at the same time?
When I use the digital out, and I run a 'test' with the analog out, I can hear the test signal so technically it should work.
However, I can't find the right settings to actually use both outputs (same source: for instance iTunes) at the same time.
Any advice? Thanks in advance!
Regards,
Jeroen

My old msi cuba 7301 from 2007 has an spdif output, and I was able to use this digital out together with the 3,5mm line out (which I used for my headphones) simultaneously. I understand what you're saying, but I'd say the user should decide in what way he/she wants to use the product . Technically, it shouldn't be a problem, since I can hit the 'test' button and hear the sounds through my headphones via 3,5mm stereo out, while playing music through the digital out.
Anyone from MSI who knows the answer? If it was possible in 2007...
Thanks for your answer

Simultaneous digital and analog with pulseaudio [solved]

Goal: have pulse audio output audio over HDMI and through line-out.
I found this thread which details two potential solutions to this problem. The more complex one isn't appealing to me, but the simplistic one quoted below is... but I can't seem to get it to work.
doorknob60 wrote:
Or easier solution this should work: open paprefs -> Simultaneous Output tab -> Check the box -> Switch to the virtual device in gnome's settings or pavucontrol
That's what I do to simultaneously output to my speakers and to HDMI, so I'd assume it would work for you too, even though you seem to have already figured it out.
Is anyone successfully doing it? My problem is that within pavucontrol>playback I cannot seem to select both the analog and hdmi sources. For example, I have mplayer playing a movie (should be HDMI) and mpd playing music (should be analog). My only two options under pavucontrol>playback are:
*Internal Audio Analog Stereo
*Simultaneous output to Internal Audio Analog Stereo
I have no option for HDMI.

Got it! The key was understanding that whatever is selected in the GUI is the default device. I therefore selected HDMI as the device and added the following to
/etc/pulse/default.pa
### Load analog device
load-module module-alsa-sink device=hw:0,0
load-module module-combine-sink sink_name=combined
set-default-sink combined
After a restart of pulseaudio, I simply went into pavucontrol and defined which program would use which device. I'll update the wiki with these when I have some time. Thanks to doorknob60 for his original post.

Connecting 5700 with laptops' only digital AND analog output

Hi everyone!
Although I'm an experienced creative user this is the first time I'm posting. I looked trough the forums but I couldn't find any answer to my question and I hope this is not the "n"th time it is asked...
I have Inspire 5700 Digital speakers and I recently bought a Sony VAIO VGN-FES laptop, with an Intel 945PM Express chipset, which features Intel HD audio. In the sound setup utility of Sigmatel HD audio, there is even an option to enable digital SPDIF output, which I enabled. But when I connect the digital din cable to my laptops only output jack (headphones...) I have no sound at all...
I thought that it may be due to the fact that the jack is not digital only. But I still want to have real digital 5.1 audio. So could anyone tell me how I can do that?
Thanks beforehand!

Addlclove,
in the sony forums the answer I recieved was that the headphone jack was normally 2.1 analog, but I didn't receive a fulfilling answer to my query about the reason to the spdif setting in the setup utility and the chipsets features. That's why I came here The only output I have on the computer is the one for the headpohes. But there is a docking station that I could buy, having an optical out.
And Jason-CL,
You're right, I used to have an Audigy, and I understand that you're saying that I can't do it through the headphone jack, right?

How to use both digital and analog input modules in the same worksheet - MCC USB1208LS

Dear all,
Hi, I am Imran. I am using MCC USB1208LS. I have created the worksheet using digital input module as below and able to execute (run).
But when i add another analog input module in the same worksheet and executes, An error Message pops-up as in the below image
I have connected temperature sensor sognal to the analog input of USB1208LS. When using analog input alone in the worksheet, it indiates the actual values.
is any black box solve? please guide me. I am attaching in images
We already placed a purchase order for USB1208FS. Will it sort out my issues?.
Thanking you,
Imran Mohamed.

Hello Imran,
the USB-1208LS is not capable of running concurrent operations such as an analog input scan and ANY digital Ins, Outs, counter reads, or analog outs. In Dasylab, the 1208LS is scanning, and nothing else from that particular device can be requested of it while that is happening.
Yes, using the 1208FS will resolve some of these issues.
Please refer to the ULHELP.CHM file installed on your computer in c:\program files\measurement computing\daq for details on this issue, et al.
also I recommend you send your MCC/DASYLab requests for support to [email protected] as MCC staff (that includes me) does not normally monitor NI's Developer Zone.

What are the separate "digital" and " analog" cable (or wires) for that connect inside pc c

, you know the ones I mean. They go from the cd/dvd rom dri'ves and then to, in my case the SB audigy 2 card.
Can someone tell me if they are needed, what they are used for if they ARE needed and the diff. between the analog and digital functions of the wires?
And anything else abou them, because I used to use them be then stopped and I dont see any loss in functions of my computers sound!!!

Mattyboy,
If you are using XP or 2000 then these cables are no needed. If you are running earlier versions of Windows, then you need these connecters for you to get CD Audio and DVD Audio to the sound card.

Newbie: 6020E (USB) slow performance with mixed digital and analog input

Hi,
I'm using a 6020E to do analog and digital input, and I'm getting very bad performance.
Please note that doing IO in Labview is new to me!
I have read the post about 6020E slow performance, and it says I should do buffered IO.
Can anybody point me to some DOC or SAMPLE that actually shows or explains how one should do this. I need to read several digital IO lines (which I can combine in one port-read), and several analog inputs.
Seeing how slow the reading on the 6020E is, I am amazed there is only one post that deals with this issue.
I would be satisfied to get the 6020E into some sort of continuous read mode so that whenever I need data, I get the latest reading right away.
thanks,
Peter D'Hoye

Hi Peter,
Your cannot do buffered digital I/O with your daqpad. It doesn't have that capability. You can only make direct software calls with digital read/write from/to your port. So your digital IO is completely software clocked and not hardware clocked. The example you are trying is only for specific Simultanuous sampling boards or now also for M-series boards that are able to do correlated DIO.
Use the Cont Acq&Graph Voltage-Int Clk.vi example for your analog measurements. (NI Example Finder) For your digital IO you can only use the examples like Read Dig Chan.vi, Read Dig Port,...
There are indeed some slow performance issues with single point I/O Operations, that is correct.
Check the explaination below:
DAQPads are offered for the Universal Serial Bus (USB) and the IEEE 1394 (also known as FireWire). Both of these standards use a high-speed serial communication protocol between the computer and the device with a bandwidth up to 12 MB/s for USB and 400 MB/s for FireWire.
During a single point operation, the DAQ device requires a complete set of configuration commands. This is done through serial communication (USB or FireWire), making the process slower than in a PCI-based board. The speed obtained for single point operation in a DAQPad is system dependent; this means that your computer processor, memory, bus speed, and other factors alter the speed at which you can do single-point operations with a DAQPad.
For example, on the DAQPad-6020E, timed non-buffered analog input operations are limited to about 50 Hz. At higher rates, the software may become unresponsive. On a FireWire device, you can expect stable operation around 3,000 Hz. But again, these figures are system dependent.
Regards.

RTP stream - record and listen simultaneously ...

Hi!
I would like to record and listen RTP stream simultaneously, but I don't know how... I can record to a file OR listen in headphone but just separately.
If i create a datasink for recording on a port I cannot use that port to listen. But in this case how can I listen the audio stream on headphone?
Maybe the good solution would be for me if I could clone the stream but I cannot do, because I get an exception
javax.media.NoProcessorException: Cannot find a Processor for: com.ibm.media.protocol.CloneablePushBufferDataSource@1d8957fThis is the code:
DataSource ds = Manager.createCloneableDataSource(Manager.createDataSource(media_locator));
processor = Manager.createRealizedProcessor(new ProcessorModel(ds, formats, outputType));Has anybody got any idea?
Thanks!

I'd point you in this direction initially.
