VERY VERY VERY EASY (now, when I solved the problem, not before...!!!)
Insert Micropone or any jack in Micropone Input or Aux Input, on your sound card or motherboard !
AND NOW YOU CAN USE PREMIERE PRO 2.0
Enjoy

Premiere Pro 2.0 and Windows 7 - Direct Sound Input soundcard driver problem

My XP machine crashed, I reinstalled Premiere Pro 2.0 with Windows 7, and I got the following error: 'The Currently installed soundcard driver does not support Direct Sound Input. Recording audio is not possible.' The soundcard drivers are updated. Any ideas? Here's what I have: AMD Phenom II X4 965 Processor 3.40 GHz 8 GB, 64 bit. Thank you for looking.

Thanks! Though I upgraded to solve the problem, this is good to know.

Stft from sound input VI dat to plot spectrogram, whats wrong?

Hi everybody,
I listen continously
via a microphone and sound card to 25ms long pulses in the range of
9kHz to 12kHz. I get 10000 samples from my Sound Input VI and use the
STFT Spectogram to plot a spectrogram(frequency versus time). Using the
default settings or any other window lengths results into the error
message:"...possible reasons: invalid windows length".
What's wrong?
Thank you very much,
Martin

Hey Brian,
I would like to listen to 25ms long pulses in the range of
9kHz up to 14kHz
+by using a microphone and a standard PC sound card
+continuously up to 1.5 hours.
The VI should display a real-time spectrogram(frequency versus time) like in the example VI "Moving STFT PtByPt.vi". It is important that the spectrogram always shows the last 5 minutes and the current frequencies. It is not necessary that the spectrogram is very real-timed(up to 600ms delay is ok), BUT it has to be 100% CONTINUOUSLY to not miss any of the short 25ms long pulses.
In addition I also would like to determine the frequencies of the received pulses, which are somewhere between 9kHz and 14kHz and I need to count the amount of received pulses.
My issues are:
1. missing some 25ms pulses due to problems with continuous sampling of SI Read VI in a while loop(I guess there is a small break between the 1000 samplesets)
2. How connect SI Read VI output to STFT VI or STFT PtByPt VI to perfom moving spectrogram?
3. Why doesn't show my spectogram no frequenciues at all?
I hope this helps to understand what I try to achieve and in what problems I have run.
Here is a corrected and more use-friendlier version of my VI.
Thank you very much,
Martin

975x Sound Input problems

I recently build a new computer using the MSI 975x mobo. The only problem is, I seem to have some issues reguarding sound input.
All the sound features seem to be working except for sound input. In Sounds and Audio Devices, I have full access to sound output and all the different volume controls and advanced features. All is well here. But when I change it to sound input I run into my problem. In the Master Volume Control on Input all volume controls except Master are greyed out to me and can not be changed.
In properties, the advanced button for input (where you can find the useful feature of mic boost) is also greyed out.
I am running the bios off the CD and the latest sound drivers. Is this a known issue and does it have a fix?

Are you wanting Sound Capture via CD/DVD or Mic? Are you running 6.1 or 8.1 Speaker setup?

Sound input problem

I have a weird problem: in using a headset to make calls using Skype or iChat I cannot get the headset microphone to work, though the earphones work fine. Everything is plugged in correctly. Have selected the Line-In option in the Sound panel of System Preferences, but the Input Level indicator shows no sign of life. Have selected the same option in Skype. Have also tried a 2nd headset, with the same result. For reference the built-in microphone works fine.
We have 2 iMacs here displaying the same symptoms; what's happening? The headset worked just fine prior to upgrading to OS 10.6.6; is there a link here?

Having banged head against wall for too long I finally took my computer to Apple, where it was determined that there’s nothing wrong with the microphone port; however, the Radioshack headset does NOT work with the sound input device set to Line-in; input device MUST be set to internal microphone, after which the headset microphone AND the internal microphone will BOTH pick up sound simultaneously. Go figure.
May have something to do with the audio-in port requiring an externally powered microphone as per users manual. From MacWorld: If you have experience with multimedia headsets and the Mac, you know that Apple equips Macs with a line-level audio-input jack—one that doesn’t work with microphone-level audio sources without amplification.

I am not getting any sound input on my microphone. There is no microphone input on my new macbook pro, so I am using my old one. Is this a problem with the new operating system? Did they simply remove any microphone software?

Check System Preferences > Sound > Output
Make sure the correct device is selected.

PLEASE can a AE from NI take a look at my problem. Sound input read behave in strange manner then the buffer size is larger than 2X number of samples to read.

On my computer I have discovered some strange behavior then reading data from the sound card. Then the buffer size is 2x samples to read everything is as expected. But since I read the sound card 10 times pr second I feel a .2 second buffer is to small. I am using XP, and XP is not a RTOS so with a buffer set to 0.2 seconds I may lose data. Therefore I set the buffer size (number samples/ch on Sound Input Configure.vi) to be in range of 2 seconds. The result then is that then reading from Sound input.vi, a reading often take more than 0.1 second. On my computer it is often 500mSec. Then the next 5 read follows with almost zero interval. I do not loose data. But on my front panel the graphs looks like an very early silent movie. This error was introduced in Labview 8.x. To be honest I think the labview 7.x sound system was much better in many ways.
But before I point any finger NI. Other people has to verify the behavior I experience. I have made an example showing this error. It is a modified version of the "Continuous Sound Input.vi" example. Then the "buffer in seconds" control is set to 0.2 every thing works OK. Changer this to a larger number will produce the mentioned above hiccup. The larger number in this control the larger hiccup. Is it any way to fix this? My solution up to now has to use a free 3. part software(http://www.zeitnitz.de/Christian/index.php?sel=waveio) But I guess it soon will be outdated. It may not work with newer windows versions.
Any help at all will be appreciated
And yes I have the most updated version fo DirectX. Also I se this in Labview 2009 which I have trail version of. The VI I have made is in 8.6

Continuous Sound Input with timing.vi ‏23 KB

macaba wrote:
If you take a moving average of the 0.2s buffer vs. 3s buffer at an update rate of 10, then they are the same (just under 100ms), so the average refresh rate is the same. I agree that is odd behaviour that the time between sound reads go to zero quite a lot then take a long time once in a while (presumably to fill the buffer
I guess it goes to zero because it is reading data from the buffer it do not has to wait for data from the sound card. The mysterious thing is the periodic delay. You are also correct then saying that average timing is correct. And in my application I have no data loss.
If you search for sound in this forum you will find out that many people has reported trouble with the sound system.

Try going into your settings and 'reset all settings'

Sound Input Problems Using iChat..Inadvertent Loss of Microphone?

My father-in-law just bought a new 17 inch iMac with an Intel dual core, whole ten yards. Great machine. However, when using iChat with his family he's noticed the the sound input goes dead and then he's constantly searching around with on screen controls to get it back again. I thought it might have something to do with his mighty mouse being that you can sync applications with it. I've walked him through the system preferences to get the sound back, but its seems to be a niggling weird type of issue. Any suggestions?
iMac G4 Flat Screen Mac OS X (10.4.1)

Hi Phillip,
Selelcting mute is normally a mouse and click item or from the Video menu of iChat (It does not seem to have a keyboard short cut).
The Mighty Mouse does seem to be the bset place to look.

System Preferences Sound Input is stuck at Soundflower (64ch). I can't change it!

So, I have a mid-2010 MacBook Pro running OS X Yosemite (latest version). (250GB HDD, 4GB RAM, 2.4 GHz)
I wanted to record some commentary for my video and to use the mic I went into System Preferences > Sound > Sound Input.
With my mic connected, I tried all of the 4 options (picture below), but then after closing and opening System Preferences again, the sound input is stuck on "Soundflower 64ch).
When I try to change it (e.g. Built-In), it "crashes", but not really: It selects the option I clicked for a second or two, then the list disappears and says "No Input Devices" briefly, then the list reappears with "Soundflower 64ch" selected.
Please help, I've tried some solutions I found online, like restarting the laptop, repairing disk permissions, even a code for Terminal.
Thanks to anybody in advance.
UPDATE: ****, I think my Mac is possessed or something. It shows the ring of death when my mouse is on the System Preferences window, and when I try to take a screenshot of the list itself, it lags and doesn't let me take it until "No input devices found" appears.

Either remove "Soundflower" or refer to its developer for support.
Any third-party software that doesn't install by drag-and-drop into the Applications folder, and uninstall by drag-and-drop to the Trash, is a system modification.
Whenever you remove system modifications, they must be removed completely, and the only way to do that is to use the uninstallation tool, if any, provided by the developers, or to follow their instructions. If the software has been incompletely removed, you may have to re-download or even reinstall it in order to finish the job.
I never install system modifications myself, and except as stated in this comment, I don't know how to uninstall them. You'll have to do your own research to find that information.
Here are some general guidelines to get you started. Suppose you want to remove something called “BrickMyMac” (a hypothetical example.) First, consult the product's Help menu, if there is one, for instructions. Finding none there, look on the developer's website, say www.brickmymac.com. (That may not be the actual name of the site; if necessary, search the Web for the product name.) If you don’t find anything on the website or in your search, contact the developer. While you're waiting for a response, download BrickMyMac.dmg and open it. There may be an application in there such as “Uninstall BrickMyMac.” If not, open “BrickMyMac.pkg” and look for an Uninstall button. The uninstaller might also be accessed by clicking the Customize button, if there is one.
Back up all data before making any changes.
You will generally have to restart the computer in order to complete an uninstallation. Until you do that, there may be no effect, or unpredictable effects.
If you can’t remove software in any other way, you’ll have to erase and install OS X. Never install any third-party software unless you're sure you know how to uninstall it; otherwise you may create problems that are very hard to solve.
Trying to remove complex system modifications by hunting for files by name often will not work and may make the problem worse. The same goes for "utilities" such as "AppCleaner" and the like that purport to remove software.

Sound input read multiple soundcards

Heey everybody,
I have a problem. I want to read two different signals at the same time from 2 different soundcards. 1 internal soundcard from my laptop, and 1 usb soundcard.
So i used the Acquire Sound VI.
Reading both signals at the same time is not a problem until i set the measuring time to about more that 30 seconds. It gets a buffer overflow.
So i tried to do the following:
I first made this with 1 signal first, and it worked perfectly, every second it got updated.
But, when i added the second signal it only wanted to read the first second of the first signal and then it got stuck, and i had to stop the software by closing it. And then killing labview with the taskmanagement thingey from windows.
Anyone have any idea what the problem is?
Greetings,
Jory
Solved!
Go to Solution.

Ok, never mind, i've solved it. I made the buffers larger (at the sound input configure block) and now it works like a charm

Sound Input Read VI hangs

I'm using the SI Read VI to sample from the Soundblaster card in my Dell PC. I've configured the device for 16-bit mono input, sample rate 44.1 kHz, and the buffer size is 1024 samples. The SI Read VI is in a Timed Loop whose period I've set to 23 ms (1024 / 44.1kHz). Following each acquisition, I do some filtering, frequency analysis, and plotting inside the loop.
The acquisition works well for the first 10 minutes or so that it is running. But sometime after about 10 or 15 minutes, the VI hangs. I've traced the hang back to the SI Read VI, but have not yet figured out how to avoid the hang or recover from it (I have to abort and restart the program).
Has anyone had similar problems with the SI Read VI? Could there be a problem with the DLL that the SI Read VI calls? Are there any upgrades or fixes for this? Can someone suggest a way to recover from the hang?
Thanks for any help,
Mark

Hi everybody,
From the large count of how many of you guys read the above thread of messages, including myself, and who are dealing with the same problem of SI Read VI hanging found National Instrument (NI) LabVIEW (LV), I decided to share my (not so perfect) solution with you guys to save you time and frustration. Here is the story of 3 days (18 hrs/day) of my life, fighting a bug in SI Read VI (SI: Sound Input) (I am currently using LabVIEW Pro v 7.1.1):

Sound input and output not working

Last night my audio was working fine. I was going to record some stuff in garage band and had a microphone plugged into the input line-in on my macbook. everything was working fine still, turned on the "auto leveling" and then put in my headphones. i then turned on the "monitor" to get the sound to actually come to my headphones. I didnt realize until after it was done but you cant have the auto level and monitor on at the same time. There was a short blast of sound in the headphones and then everything cut out. I couldnt get sound from anything, headphones, built in speakers. No sound going in either.
I restarted my computer and if I remember correctly (maybe i'm imagining it) there was the start up chime. when I started up garageband again I got an error message reading "selected driver not found. error 10202" still no sound input or output. When trying to adjust the volume all I got was the grayed out volume thing with the little cross thingy at the bottom. I checked the sound settings and there was nothing in the input or output sound.
I did some searching around and saw people with similar problems (none with an answer).
This is what I've already tried:
I reset the permissions
I reset the PRAM
I did a hardware check (hold d which restarting) i even did the hour long check and there was no problems.
I tried putting headphones in an out (there was no red light in the headphone jack)
I updated all my software (there was an update to OS X to 10.5.8)
After the update there was no longer a startup chime, and i got no error messages when opening garage band. however there was still no input or output sound. when adjusting the volume on the screen it appears to be normal, but there is still no sound from built in speakers or headphones. I did notice there was a very faint "clicking" noise when i try and adjust the volume... like the speakers are getting power or something... but then nothing comes out. In the sound settings there everything appears to be back to normal.
I know this is long, but I wanted to be thorough in describing my problem. I'm posting this on several boards as well.

I'm having the exact same problem. I did install the newest version of Skype the last time my computer was running (with sound)... so not sure if the new Skype had something to do with it.
Also, when I try to change volume with the keyboard keys, there is a little icon (circle with slash) indicating that the sound has been disabled or not allowed to be changed.
I can't find any answers on any forums.

Bootcamp 3.1 & Windows 7 x64 - no external sound input, low speakers level

Hi all,
I just installed long awaited Bootcamp 3.1 update. I am rather disappointed.
The only thing that has changed is that the red light on the audio output is off. This thing actually bothered me the least.
External sound input line does not seem to work at all. No matter if mike or standard line device is connected. System recognizes that something is connected but there is no sound coming, level indicator does not rise.
Speakers level is still low. As far as I know all it takes to fix it is to alter some settings in the *.ini file. Someone did it and posted for other to download but why it is sho hard for Cirrus and Apple? What is the matter?
Is there any way to get sound output via Mini Port under Windows 7?
System does not even see such device.
Thanks,
Thomas

What about the iMac though? 2008 Model w/ Realtek to be specific. The audio is low and poor and I haven't even tried the audio out. I'm running Win7 x64 and everything works well aside from my audio and my external WD Studio FW800 drive disconnecting randomly with repeated directory changes. I can avoid that on my system... but the audio is a real disappointment. Makes me feel like I need an external FW sound card.

50L7300UC - sound input from Mac not outputting to ARC

I'm having an odd problem with audio on my 50L7300UC (Canadian model of the 50L7300U). I have a soundbar hooked up via HDMI ARC, and it works fine for audio from my cable PVR, from online sevices such as Netflix accessed through the TV itself, and from my PC (a Windows 8 tablet connected via a mini-Displayport to HDMI cable, which provides both audio and video). But with my wife's Macbook Air, using the same mini-Displayport to HDMI cable, video is fine but the sound won't output to the soundbar. Oddly, the sound does work if played through the TV speakers, but if I switch sound output to the soundbar (which the TV sees as "Amplifier"), nothing comes out. I've tried different settings on the Macbook's audio output (using the Midi Audio utility), but that doesn't seem to matter. Any ideas?

Hmm, if it doesn't see the internal microphone when connected via the FW cable, maybe you might have to run audio cables from the camcorder line output to the sound input on the Mac.
