sound generation

I'm trying to use the example of OR generate Sound.vi in LV2011(32-bit) running on Win7 64-bit. The VI is set with the default settings and the setup of sound card on Windows via the control panel is the same: SR 44.1 kHz, 16-bit depth. Windows media player works well, but the VI, I think, does not see the audio (device inherent high-definition Intel S5520SC MB). I read a text of somewhere in the developer area while ensuring that DirectX is installed. As the OS Win7 is a new facility, it would be supposed to be installed when the OS was, and indeed, there are dozens of references to directx DirectX in the x 86 program files folder. Anyone can shed some light on this problem?

Thank you

Hi, if you look at the helpof the screw sound you can find that in the Act of DirectX 8.0 or later are required to run the code. Now, drilling screw you will find that they all use a shared library called lvsound2.dll. My suggestion, try upgrading DirectX and confirm that the library is on the PC.  Another problem I can think of is perhaps linked with the device ID. Try to play with values between 0 and 10, where the audio output is indexed from 0 (default).

  • Sound is played at the first time when it is called by VI

    Hi, I am creating a VI that creates bursts of noise of specific terms in the sequences. My problem is that the sound generation VI only plays the sound the first time it is called. I tried to put VI in a for loop to see if I can get to play several times, but no matter what I do it plays only generated sound once.

    I found the problem. Thank you. The problem was with the timer not reset in the loop (it fixed with a shift register) on second or other calls. Thus, the loop was ignored that the timer has been greater than the value specified after the first time through the loop.

  • video iPod 5.5 generation, Sound of Dock - None of helmet

    Hello

    I've been browsing the forum here among others trying to figure that this somewhat strange question out and I finally decided to see if anyone here has an answer. I recently bought an iPod video 5.5 opportunity generation 30 GB (A1136, model #: PA446LL, SN: * V9N) out of craigslist. The iPod seems to be fully functional, aesthetically and hardware wise. Up to what I tried to listen to a song via the headset. To my surprise, there was no sound coming through the socket. If I turned the volume all the way to the top, I could hear a slight static noise (not related to music), so I guess that is under tension. I read online that this can be caused by welding cracked on the audio decoder or dac, so I tried pinching right/bottom right corners without changing the static at all. Thinking that I had just bought a broken iPod, I tried to play this music even through my car stereo receiver using the dock/usb connection and it worked perfectly. A little confused at this point, I took the thing out and inspected the cable jack and Ribbon of the helmet, the motherboard and audio chips. Everything went perfectly well, including headphones and cable, it was not folded connections inside and it was clean. I tried to press the chips on the motherboard, while playing music once more it is taken apart and it was not even a change of the static (when volume is 100%). I tried various headsets/headphones and with each of them, as you are connected to the socket you can hear precisely the left channel and then the right gets their power.

    I've read only a few cases of this particular issue happening and the response to each of them was to get a replacement headphone plug. I am skeptical to do what I can hear both channels is fed fine, there is no audio. I ask if someone who has some expertise on this motherboard (820-1975-A) knows where the problem lies (audio impeccable out Dock but headphone jack has absolutely nothing). I have the tools needed for soldering and re-flow if necessary.

    I tried the things:

    -Different headphones/earphones

    -Cleaning of the headphone jack/re-seating the ribbon cable

    -Tighten more integrated chips while music played

    -The 5 'R' apple suggests (including restoring w / mac & windows several times).

    -Different file formats (ALAC, MP3, WAV (16-bit, 44.1 kHz))

    -Hard reboots

    -Possibility of other things I don't forget

    Things I'm NOT willing to do:

    -Return to the craigslist seller

    -Apple call / go to an Apple store for a replacement

    -Buy a new logic board (I understand the one I may be impossible to fix)

    I appreciate your time and I hope that the heart of this problem can be highlighted!

    Current configuration is a Samsung TV with a Samsung blu - ray surround sound.  When both are on they use anynet to communicate. Now with the new apple TV 4, any click on the apple TV remote will send my TV HDMI 2 (where the entourage of blu - ray is connected). How can I stop this? The apple TV is HDMI 3.

    Any type of error handling?  My guess is that the paths changed on you and the executable knows more where the .wav files.  But you won't know unless you make your own error handler because the automatic error handling is disabled by default in an executable file.

  • Generation safely notification that emits a sound custom installed

    My application needs to read a custom (specific sound which is subject of the application) when it alarms.  Since there is no stripped of notification settings control which would allow me to install the mp3 and set it as the default notification, I resorted to the construction of a custom notification and the consequence, based on the example of Notifications.  However, when the notification is issued from my background thread, there is no way to detect the keys (since this cannot be done in the background), in order to stop playing the sound.

    My questions are the following:

    1. What is the best way to approach a sound packaging custom notification so that the user has normal BB experience, including the silent power all sounds press a key?

    2. in case I do is on the right track, can you think of a way to get a notification that a key has been pressed to cancel playback of the sound?

    Thanks in advance for any thoughts!

    No, it is not possible to capture the keys while a BlackBerry is locked.

  • 3rd generation ipod white screen

    I know it's old, but working well... so far.  White screen.  It is recognized by itunes when plugged into the computer.  Restored successfully on the itunes screen, always white.  Tried the fix with holding home and power button.  Tried to hold the House, volume and power.  Screen remains white.

    My question - is all hope gone and I must finally remove this ipod?  It's been great and it's a sudden death - hard to see it go.

    Thanks for any help...

    The 3rd gen iPod "classic" has a great sound.  If you tried to do a restore already, its likely to be a hardware problem, unfortunately.

    These older iPods are easier to repair because they are assembled from items separated and not so integrated and miniaturized.  My work 3rd generation iPod was reassembled broken iPods that I bought on eBay, by swapping pieces.  The screen is not the thing that is broken, most of the time.  If you are somewhat technically inclined, you can remedy.  You can post back for more information.

  • Does anyone have a work around for the design on PowerMac G5 2005 flaw that causes noise interference on the outputs? (Audiophile, sound engineer)

    OK, here's my problem - I have a set of audio interface Protools Digi 002 via Firewire 400 on a PowerMac G5 I was lucky enough to be given last year. I finally managed to connect my home recording studio system, he wire of mixer etc, but when I listen to the music coming from the outputs of the Digi 002 there in a great cacophony of audio interference, so much and so well, when I mount the system I can move my pointer between two monitors and it plays a different frequency of buzz. Everytime I open a window, Soft etc it is more electronic noise.

    He took a while to limit, but after reading this excerpt from wikipedia, it seems that it was a fault common to this particular model until Apple released the revised version of the B of the G5 (?);

    ' The first versions of the dual processor G5 have problems of noise . The first is ground loop- based interference,[5] that sometimes causes noise seeps into the outputs audio analogue. This bug has been fixed in Rev. B G5.'

    and

    ' Well that the noise problems do not prevent computers affected work, they asked problems for audio professionals and enthusiasts as well, especially for models to liquid cooling, which had been expressly designed as mechanically quiet for listeners. "

    Well, that's no euphemism - in fact it makes the mac completely useless for my needs, I need the outputs clean digital noise to send for outboard effects/EQ/etc.

    As it was a common fault, I was hoping someone might be able to shed some light on a workaround solution, as I can't imagine recording ground studios just stop until this has been fixed by releasing a new G5?

    The only idea that I came up with so far is to buy a transformer of isolation, but I'm not entirely convinced that will solve the problem?

    Any help on this would be greatly appreciated!

    Thanks in advance

    Have you tried CHUD Tools & turn off NAP mode?

    The first versions of the dual processor G5 have problems of noise . The first is ground loop- based interference,[5] , which causes sometimes analog audio output sound leaks. This bug has been fixed in Rev. B G5.

    The second problem of noise came from his "tweets", which can be triggered by power fluctuations. For example, display or hide the Dock makes a short beep. Many blamed the power supply used in the G5 as the cause, but this theory has never been confirmed. A very effective workaround is to disable microprocessors 'siesta' using Apple CHUD Tools, but this was not recommended by Apple. This noise problem has not set until the generation of dual-core G5s was produced, but it does not affect the model of "Late 2004" (at least there have never been reports). Draw of power fluctuation has been later attributed to the lack of power management features in processors simple heart. [6] Apple eventually posted information bug tweets on its support site. [7]

    Although noise problems did not prevent the computers assigned to work, they were problematic for audio professionals and enthusiasts as well, especially for models with cooling liquid, which had been expressly designed as mechanically quiet for listeners.

    https://en.Wikipedia.org/wiki/Power_Mac_G5

    Just one last note on the use of CHUD tools to disable the 'Nap' on the G5 Dual functionality: restart your machine reactive 'Nap '. You may have already seen this on the Apple forums. Kind of a bummer - although I rarely shut down my machine. In any case, running with 'Nap' off today seems to have resulted in a significant increase in general speed/responsiveness for me (I'm still running the stock 512 MB RAM, with another 1 GB on the way).

  • ATV4 - bad sound

    Hello

    So I have this problem with Apple on the ATV4 music. The sound is really muffled and distorted. I changed the output 5.1 auto in settings and it seems to be a slight improvement, but is not the only striking sound is still not clear. Songs played on TV channels or Youtube all the normal sounds, but the app Apple music songs are suppressed. Apple music is called to play always more high quality, whatever the internet resources. And internet high speed is 1 Gbps.

    Config: ATV4

    TV: Sony 50W815 (2014 model)

    Audio system: Sony DAV-TZ140

    ATV4 connects via a HDMI cable to the TV. There is highspeed, latest standard. It connects to the internet via an ethernet CAT7 cable.

    Help, please!

    I know you said the sound is muffled and distorted but there could be something in this support article for help.

  • 4th generation Apple TV connected to the projector

    I have an Apple TV 4th generation connected to a projector with a Kenex of HDMI to VGA with Audio for the 4th generation.  Whenever I want to play Netflix or HBO NOW I get a black screen. I can only here the sound and I get a black screen.  It works fine when I use other applications.

    What can I do to fix this?

    I would really enjoy HBO NOW and Netflix with this number.

    I think that your card does not support HDCP on the HDMI connection, which is required by these suppliers copy protection. Because you want to convert it to VGA, this isn't surprising, because an enterprising hacker could extract the digital video stream. Most of these adapters are sold "educational purposes", not the home entertainment, and that's why. That said, if you look diligently, you can find a suitable adapter. The educational goal of the KENIMBENI is actually mentioned on the Apple store page http://www.apple.com/shop/product/H9139VC/B/kanex-atv-pro-x-hdmi-to-vga-adapter-avec-audio-prise supported, as well as a comment by the user that it cannot handle the HDCP.

  • IPad 4th generation a worthy upgrade?

    Hello, I guess the title speaks for itself. I have an iPad 2 and explored a generation IPad 4th instead of one of the most recent Air.  The thinner air worries me a little after reading the reviews on the problems of vibration, but at the same time, I don't want to get something that will be essentially unusable in a year. I mainly use my iPad for navigation, email, youtube, netflix, and some older games. I have my laptop for heavy lifting.  All thoughts and opinions will be greatly appreciated.  Thank you.

    Forget an iPad 4.

    They came out the same year as the iPad 3 and a 4 year old machine, may be rendered obsolete earlier than the most recent models of iPad.

    Get the new iPad 2 air or if you want stronger, better sound quality for music and movies, consider the iPad 9.7 inch Pro.

    If your budget allows, for the iPad 2 Air, Apple is only in charge $100 more for three times the size of the basic storage model of 16 GB which, IMO, is a real bargain!

    Newer models of the iPad don't WILL NOT go unusable or obsolete in a year!

    I don't know where your thinking with this, but Apple will always come out newer, faster, better iDevices each year (just like cars).

    You should get at least another 4-5 years, or more, out of the current range of iPad. NOT FOR A YEAR!

    The only iPad, which took his life cut short/low was the original iPad in 2010.

    The original iPad was only about a year and its iOS has NOT advanced before iOS 5.1.1.

    Vibration problems were not a problem if your put your iPad into a kind of light and protective case.

    So your new iPad AppleCare extended supplementary estimates a 2 years warranty complete Apple for all the problems.

    Good luck and have fun with your new iPad.

    It will be a difference noticeable a lot in performance than an iPad 4 years 4.
