• EliteBook 8540w: no audio signal through DisplayPort

  I'm trying to connect my laptop to my TV through DisplayPort. I bought an adapter DisplayPort to HDMI cable. The image is fine, but no audio is coming through. I don't see TV as the device in the sound Panel, and I have only (not Intel) IDT audio control panel.

  Any ideas?

  Solved.

  It was in the latest versions of the NVidea driver. I uninstalled the driver and then installed the driver that was originally shipped with the laptop (Oct 2010 driver version). The TV came immediately as playback device and its working now.

• ProBook 6540 b: no audio signal through Displayport

  The Displayport video output on 6540 b does support audio? If so, how I would allow sound through displayport through the windows? I was not able to get sound to participate in one of my TVs that has DisplayPort inputs.

  Hello:

  It's possible this is the case.

  There are a few PCs that do not support audio out of the view port.

  I was hoping that it works.

  What would you say to the manage audio devices in the hardware and sound section in the control panel?

  You see two audio devices listed?

  The laptop speakers would be the IDT audio and if you see an Intel HD audio device, for the display port.

  The only suggestion I can offer would be to connect to a display port, select the Intel HD audio device in the window and see if it works.

  If you do not see the two audio devices listed there, so I doubt he's has supported audio out of the view port.

• Re: Portege R100-11Z no audio signal through headphones/mic not taken, via its USB OK

  Hello

  I did a clean install on my Portege R100-11Z of windows 7 and later a new clean install of Windows XP Prof SP3.

  In both configurations, I have no sound from the headphone/microphone jacks. (yes I check all the options: mute / his wheele next / new drivers / Toshiba eliminate program "mute" e.t.)
  All the configuration looks OK. I don't see anny WARNING/message in the configuration settings.

  But I hear via a USB headset via the USB.

  Looks like the built-in sound card Driver works OK because I get the sound through the USB.
  What is the solution to get the sound through the headphone/mic shots?

  Thanks for your help/advice.

  > In two configurations, I have no sound from the headphone/microphone jacks.

  But that the sound from the speakers?

  Theoretically, it could be possible that the headphone is faulty

• Alienware m14x R2 no signal through HDMI

  Hello. He machine Alienware m14x R2 i7-3630QM GTX 650 M. Faced with this problem:
  When you connect an external monitor via HDMI, there is no image, while sound is transmitted and the monitor is determined by the system pulls the native resolution in the display properties, but there is no picture. I've tried different monitors, different painkillers to reinstall the driver. I asked as the site of the factory in DELL in accordance with service number and all the news on the Nvidia site. Just do rekaveri. I change the monitor and in the display properties settings. The result is the same. At the same time connected via mini DP image is transmitted normally.

  Please help me :(

  I will recommend you to completely uninstall the video drivers and install the latest version from the Dell support site, the monitors as well on a no duplicated extended connection.

  Have you tried with another HDMI cable?

• BluRay HDMI'd to the TV, TV audio digital-to-analog converter: no audio signal to the receiver

  I have a BluRay BDP-3100 connected to the TV via HDMI.

  I can hear audio (DVD, Netflix, etc.) very well just the TV speakers.

  Have TV audio out audio output digital (optical) > (RCA) digital audio converter > receiver for playing on the sound system.

  I get no audio through stereo receiver, DVD or Netflix, only a heartbeat noise. Funny thing is that I can hear YouTube with this configuration only.

  All the other audio (cable, Xbox) works very well with TV audio out through receiver converter.

  HEY Santa, thank you.

• Audio transmission of HDMI to SCART on Toshiba REGZA TV 46SL863

  I have a Toshiba REGZA TV 46SL863

  I use a home theater 5.1 for audio from the TV via a port SCART (only possible connection)

  However, when I receive a signal via HDMI (my ps3) I can't get the sound to play on the home theater. The question is:

  * Is it possible to transmit the audio signal from a digital source to the SCART? *

  If not, what devices should I buy for those who do? Unfortunately, my 5.1 only accepts entries via a port SCART...

  Hmm I never tried this link, but I guess that it is not possible to mix digital and analog signals.

  In my case, I connected the PS3 directly to my HiFi receiver.
  PS3-> HDMI-> HiFi-> HDMI--> LCD

  and generally it s common way how such device must be connected.

• Toshiba 32TL933G: No Audio signal in PC mode

  No Audio in PC-Modus!

  Is it possible to go from Audio IN to the PC Input?
  Now I have a video in PC * GOLD * Sound in EXT2, not together.
  IF not, I will return it

  Nevertheless a beautiful Asian.

  The fact is that VGA port does not provide the audio but video signal only.
  So if you a TV connected to the computer laptop s port VGA, audio signal would not be provided.
  You need connect the TV with an extra audio cable in order to get the sound.

  The laptop must be connected to the TV s L R taken audio using an audio cable additional of Y. So that you can connect to s portable headphone plug to two L R audio ports that are available on the back of TV s

• Converts the audio signals of the mydaq in discrete values

  Hi guys!

  I'm currently building a project that accepts mydaq audio signals. I wanted to analog signals it have descrete peak values. Is this possible? I intend to use the discrete peak values and sum their place by using a registry change instead of the peaks. I think it is easier.

  Any suggestions would be helpful. Thank you very much!

  Yes, the Ridge detector shows you where are the tops.  Now use a loop FOR autoindex on where are the tops for the level in those places.  Now you have a table to the top.  You can then use add table items to add them together.

• NOR-USB 9229: How audio signal acquisition?

  Hello

  It's one of those stupid beginner questions I use a module OR 9229 USB to capture the audio output of my computer line as follows:

  -left line-out goes to AI0 +.

  -right line output goes to AI1 +.

  -land line out of is divided into two and goes to AI0 - and AI1 -.

  What is the correct way of wiring?

  In case it is, I have (I think) have problems audio signal acquisition. In the Measurement & Automation Explore, I creates a task for the acquisition of voltage AI0 (44100 Hz, etc.) -nothing is displayed on the graph when I run the task! (I have music running on the computer during the measurement) Otherwise, the 9229 flashes green, seems to be ok, auto test work, etc..

  Someone has an idea what I am doing wrong?

  Thank you!

  Hi acgrama,

  That sounds like it should give you a signal any (not an empty graph or a flat line at 0 V), but the USB-9229 is not very suitable for audio:

  • The USB-9229 to entry level is of +/-60 V. A line level audio signal will use a small fraction of that. Of the USB-9229 precision and plug noise are adequate for your application?
  • The USB-9229 can't acquire them exactly 44.1 kech. / s. It supports some 50 kech sampling frequencies. / s divided by a number between 1 and 31, as 50 kech. / s, 25 kech. / s, 16.7 kech. / s and so on. When you specify a sampling clock DAQmx not taking in charge, he is forced to the top supported next, which in this case is 50 kech. / s. (you can read back the SampClk.Rate property to see what DAQmx forced the rate to.) For 44.1 kHz audio to USB-9229, you will need to re - sample the acquired data (which are specific to the programming environment).

  Assuming that you're just trying to do it for learning or experimentation, here are a few ideas:

  • Is the line connector configured as an output line? Many mothers today have reassignables audio connectors.
  • The volume of the source (wave, CD, whatever) high enough?
  • On the graph, is scaling auto turned on? If you display data in a table instead, are the numbers exactly 0 or any close?
  • The output of the line works if you are connecting to another device that is designed to handle signals to line level?
  • If you connect a battery (AA, 9V, whatever) for the USB-9229 instead, read the Max supply voltage?

• similarity of 2 audio signals

  Hello!

  I m trying to figure out how to get the similarity of the two audio signals in LabVIEW.

  I read the original signal of WAV file and do some operations with it (filtering etc.). After that, I want to know similarity of the signal (spectrogram) original and filtered.

  I don't know about two things: distance correlation and cepstrum (Don t know how to implement).

  I tried the file CrossCorrelation.vi of LabVIEW to compare my spectrograms of two signals, but I m do not know how to evaluate the result (check photo).

  I get some sort of graphic information, but how can I assess it statistically? For example: output is similar to the entrance of 80%...

  Can you show me any direction or advice?

  I have LabVIEW 2013

  I have also attached my VI + WAV signal source.

  

  Commenting on the spectrograms is probably a good start.

  If you are able to define the characteristics that are important, later, then go back and try to implement those measures.

  I think that the Hilbert transform can be used to get an envelope. I did not and am unsure of the theory, but some research can give you some ideas.

• HP probook b 6450: Hp probook 6450 b no sound through hdmi cable

  Hello

  I have a problem, because I had a virus on my laptop, I had to reinstall windows 10. Everything is working again except when I plug in my hdmi cable it does not recognize the hdmi audio output. If I look at my audio devices it says: digital audio (HDMI) not connected. I tried to put my card video/audiodrivers/all drivers to day/re-installing what I think of cound, but nothing works. Prior to the re - install everything worked fine, so I think it's a software problem, I just don't know what it is. Can someone help me?

  Evan

  You are the very welcome.

  OK, you should be able to solve this problem quite easily.

  Because HP does not officially support your laptop for W10, but graphics driver W10 works, let's add the HDMI audio driver from the file of graphics driver for W7 on your laptop support page, without messing with the display of work W10 driver.

  First of all, download and install this free utility for files.  The 2nd high page file is 64-bit.

  http://www.7-zip.org/

  After installing 7 - Zip, download and save but are not run this file from W7 graphics driver.

  This package provides the graphics driver Intel high definition (HD) with Turbo Boost technology for the notebook models and operating systems.

  FTP://ftp.HP.com/pub/SoftPaq/sp64001-64500/sp64360.exe

  Now that you have downloaded and saved the graphic driver file, right-click on it and select 7 - Zip from the list of options.

  Have 7-Zip extract of: and leave it to extract the driver file in its file name of the file (sp64360).

  Once this is done, go to the Device Manager and click on the peripheral plain high-definition audio (not the IDT one).

  Click on the driver tab, click on set to update driver.

  Select her browse my computer for driver software option and navigate to the driver 7-Zip created folder.

  Make sure that the include subfolders is enabled, and must install the audio driver.

  Restart the PC, and you should now have the video and audio via the HDMI out port.

• There is no audio signal of chronology in PREL12 the .m2ts files

  Windows 7-64, first 12 items (64 and 32 - the same result)

  Panasonic SC - 920 X camcorder, recoding format 1920x50p + DD5.1

  1. If I just copy the files .mts from an SD card into the PC and import it into PREL then there no problem with audio. It is to play the preview and timeline window.

  But in this case, I have a problem with the long record - camcorder breaks large files.

  So I use the SD instead of the simple copy import.

  2. the import of the SD using PREL12 (Get media of-> cameras Flip, AVCHD,...). In this case I get at disk .mts files and no audio timeline with these files. But in all other programs, these files are played with audio.

  3. import the SD using Panasonic HDWriter program. In this case, I get .m2ts files (and some metadata files.). These files read normally (with audio) in any player and the program I have (WMP, MPC, Corel Video Studio Pro X 6 etc.). Except the chronology of the PREL12.

  There is no audio signal of PREL timeline. And at the same time there is audio of the preview in the same PREL window (after double clicking on the item in the active project)!

  There is no yellow bar above these clips. Project settings - 1980x50p PAL AVCHD

  How to get audio of time?

  dik07

  Something for you to try.

  The quick and very rough to solve this way...

  Expert workspace...

  Before you import your media into the project, set the predefined project manually to

  PAL

  AVCHD

  Full HD 1080i25 5.1 channels

  To manually set the project preset

  • Open the project in the workspace Expert and go to file menu/new project and change the settings.
  • In the settings, set the project preset to match the properties of the source media. OK to get out of there.
  • In the dialog box new project opens, rename the project and make sure you have a checkmark next to the "Force selected setting on this project." OK to get out of there.

  And then import your source files in the project by the different ways you have tried and found not to work for your application.

  If it works, then the real solution...

  Premiere Elements does not come with a preset project to PAL AVCHD AVCHD 1080 p 50 5.1 channels.

  But, you can create one for use if gross suggests you need a project that is pre-configured with 5.1 channels included in its description. Please see details

  RTA Premiere Elements troubleshooting: PE11: export a file 1080 p 50 or 1080 p 60 with Audio to 5.1 channels

  Let know us the results and then we can decide what then.
