Output Sound

I see how to change the output in the Preferences. However, I have an older set of accessory speakers that are quite good with a sub woofer. The difficulty SEEMS to be that it does not connect to my iMac with a USB but simply plugs in to the jack on the rear of the iMac that is marked with the speaker icon. The speakers have been working fine on my PC before I switched to the Mac. Now I get no sound because the Preferences is not recognizing that I have connected external speakers. Suggestions, help, please!!!

It sounds as if you need a driver for the speakers. Not all speaker systems are natively Mac/Leopard aware.
I would search for new drivers, both USB and any firmware that might also be necessary for the speaker system.

Help! No output sound

Hi,
I'm in an emergent situation where my Macbook have no output sound. It's a Macbook, but the new lines all call them Pros. Here is what happens:
1. There is a Red Light inside the MIDI port, only in the one where the microphone sign is (the output one). I have never seen this red light before, but after a restart, it went out.
2. I checked System Preference and it says no output control device even though the laptop itself DOES have built in microphone. And the funny thing is, when I restart it, it gives me the 'boo' sound, but when the OS loads and the GUI shows, no sound.
3. I plug in an external microphone, the sound is there. But once, the external microphone is plugged out, the red light shows up again.
Please help,
Regards,
Angela

I did a quick AHT, but funnily, it reports no problem. However, the system shows a 'built in input microphone', but no 'built in output microphone'; it only shows 'built in output'. It's quite terrifying, it works just yesterday, and now, I can't even find it in the system.
I did check Audio MIDI setup application, but the IAC driver is labeled red. I mean, what is wrong with this?

Help with timing, input from Daq, output sound

Hi
I am a student member of OSA, working on a laser listener project to be used in examples for high schools students. It is a pretty old and simple experiment but something I think students would be into. {any suggestions for other experiments anyone might have I would love to hear}
I read a voltage from a Daq off a reciever circuit, that signal is noisey so I filter it for the human voice range, 60Hz - 2000Hz. Then that filtered signal goes to the play waveform express VI. It works but the snag is I keep getting a "beeping" in the output sound, I believe this is from the loop cycling. I have thought of something like a master/slave loops, storing the data in an array then waiting a sec or two and playing the sound from this data so I dont have to wait on the Daq to acquire new data. Any help or suggestions are greatly apprciated.
This is a rough version sorry about the mess. I think it should also be noted that if the "Time Duration" is larger that 0.02 then that makes the number of samples larger than what the Daq can handle.
Thank you very much in advance for all of the help and your time.

OSA example.vi ‏42 KB

Hi Jason,
I took a look at what is happening in the play waveform express VI and the issue may be related to starting/stopping the sound card every time the loop iterates, similar to what I suggested with the DAQmx VIs in my previous post. To look into the code behind an express VI, you should copy the express VI to another section of your code or to another VI completely, because once you show the block diagram for it, you will not be able to use the express VI configuration dialog anymore for that instance of the VI. Once you copy the play waveform express VI, right click on the copy and select "Open Front Panel." Then, navigate to the block diagram and keep opening the subVIs until you find the "Simple Write" VI (see below for a screenshot of this VI). Here, you will see that there is a "Sound Output configure" VI as well as a "Sound Output Clear" VI. Since these are within the while loop of your top level VI, the "beeping" in your output may be caused by the constant configuring and stopping of the sound card with these VIs. What I suggest is that you use the code in the express VI as an example to code your own sound output vi that is configured once outside the while loop and stopped once after the while loop. Hope this helps!

Trying to Output Sound to Speakers and TV Simultaneously on H8-1360t

Hi everyone -
I have an HP H8-1360t with an AMD HD 7570 video card, running Windows 7 64-bit. I have speakers hooked up to the on-board sound via a standard 3.5mm cable. I run DVI to my monitor and HDMI to my TV. I am trying to get sound to go to the speakers and the TV simultaneously, without having to keep swapping the default playback device. I tried the following that I found online:
Open Sound panel
Select Speakers as the default playback device
Go to the "Recording" tab
Right click and enable "Show Disabled Devices"
A recording device called "Wave Out Mix", "Mono Mix" or "Stereo Mix" (this was my case) should appear
Right click on the new device and click "Enable"
Right click on the new device and click "Set as Default Device"
Double click on the new device to open the Properties window
Go to the "Listen" tab
Click on the "Listen to this device" checkbox
Select your HDMI device from the "Playback through this device" list
This worked the first time I tried it and I was getting audio through both the PC speakers and from the TV. Since then, it no longer works and I am only get audio via one or the other, depending on what device I select as my default. It's more of an annoyance than anything else - having to manually switch between output devices every time I want to watch something on my TV instead of my monitor. I assumed I could get dual audio output and simply not turn on the PC speakers when I wanted to watch something on the TV and it worked the first time! I don't understand why it is no longer working. Thoughts?
TIA!

Thanks for the reply!
I believe that the answer is answer is yes to both questions - it defintely worked the first time. I'm not sure if I tried it on the first reboot or not but it did not work the next time I tried it. As far as what may have changed - I have no clue?!? I do not see that the 7570 or the Beats audio had any updates. According to Device Manager, I am running the latest IDT High Definition Audio CODEC driver.
i did notice a couple of things tonight. The video I used as a test the other day, that had audio and video going simultaneously on both displays, is displaying video on both the monitor and TV today but no audio on the TV. That said, when I open up the Sound control panel, and click on the AMD HDMI Output, right-click, and click "test", I do get test "beeps" through my TV (while the audio from my video is running through my PC speakers). So, it appears that it is indeed capable of outputting sound to both the PC speakers (via the onboard sound) and the TV (via the HDMI) - just not the same sound anymore! Another thing I noticed is that when I go to the Recording tab, the Stereo Mix selection is noted as the Default Device, and I can watch the "meter" on the right move up and down in sync with the volume of the video I am playing back - only there is no sound via the TV.
As usual, when I switch to the HDMI Audio Output as the Default Device, the sound plays fine on my TV.
This is strange...

Ipod touch no longer charges with USB nor does it output sound through the connector

2 problems after the latest iOS update:
(1) my 3rd generation iPod Touch no longer changes when connected to the computer through the USB connection. It says that the device is not supported for connection through USB. My computer is running Snow Leopard and all software is up to date.
(2) it also does not output sound through my clock radio nor through the built-in ipod connection in my MINI.
This all worked great until the latest iOS update. Something broke in the latest update.
anyone else seeing this issue?

You can try the standard fixes:
- Reset. Nothing is lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup
- Restore to factory defaults/new iPod.
If still problem then the iOS broke full compatibility. you have to then wait for either Apple to fix the problem in an iOS update or for Honda to fix it via a firmware update/
Have you contacted Honda?

Output sound distortion when USB Mic Connected

Hi everyone,
Really appreciate anyone’s help on this sound distortion problem.
I have been using the new 2014 iMac 27' for last 8 Months, bought Brand New, and recently updated to Yosemite. Everything worked fine including recording, until this update.
I'm using Blue Yeti USB Mic for recording, and few days after the update I was trying to record in GarageBand and the output sound (via headphone connected to USB MIc) started to distort and then suddenly dropped the bitrate/ sound and I could only hear some clicks. I reinstalled the GargeBand, still its the same distortion happens. The sound gets back to normal, only for few seconds, after I unplug the USB cable from the Mic device. And I tried changing the bit rate and again sounds starts to drop after few sec. This happens only when I connect the Blue Yeti USB Mic and sound output from the Mic itself. Same thing happens with iTunes as well. Output sound from Internal mic and speakers are working fine as normal.
I tried connecting the USB Mic to my Windows laptop and its working fine with the Cubase 5 without any problem. So the problem is with the output sound, when external Mic connected.
I don’t know the solution for this. Have checked on every single blog/ thread, sill couldn’t find the answer I’m looking for, to fix this.
It would be great if you have any kind of a solution for the same.

Nope. The larger buffer didn't work. What did work was running a cord out of the 1/4-inch jack from the direct box to a 1/4-to-1/8-inch adapter and then into the mic/line-in jack on my computer. I set GarageBand to use the built-in line-in and had no static problems. It's a stopgap until this gets fixed.

Docked iPod only outputs sound during video to TV

I have a 5G iPod in an Apple dock, connected to my TV using a Monster audio cable and an S-Video cable. For some reason, it only outputs sound during videos or a photo slide show - not at all for music only playback. I'm baffled! Any idea why? It's a Panasonic plasma, and I've tried three different inputs. None work for music, but video is fine.

The iPhone 4, unlike iPod, doesn't ask you to set for PAL or NTSC. In fact, in the SETTINGS/Video menu it only asks if you want to "Start Playing From Beginning", "Closed Captioning" and "Home Sharing". I was surprised it had no settings like the iPod at all.

How to output sound from Zen Neeon to speaker without using

how to output sound from Zen Neeon to speaker directly?
as far as i know, i can only play content in my mp3 player using speaker with usb cable connected to pc
i just wonder how i play using "play" button in mp3 player and the sound will output to speaker directly?
need extra line-in cable?

my speaker system is subwoofer,but i not very sure it's 2. system.
the cable from the speaker is slightly too big to connect to the player headphone jack. and no sound come out after i play.
why?

Hello gail from Ajijic,
If you'd like to change the audio output of your Mac, you can do so by accessing the Sound preferences in your System Preferences.
Before you start, open the Output pane of Sound preferences (choose Apple menu > System Preferences, click Sound, then click Output).
Choose a sound output device
From the list of sound output devices, select the one you want to use. All sound output devices available to your Mac are listed, including the computer’s internal speakers, devices plugged into your computer’s sound port (), USB speakers, and AirPlay devices.
For any device plugged into the computer’s sound port, choose Headphones.

Media applications fail to output sound. [SOLVED]

The issue here seems to be that for some reason or another applications such as VLC, Nightingale, clementine and amarok fail to output sound while system sounds, flash media, and notification sounds from applications such as Skype and Thunderbird continue to work. With each of the music players respectfully there seems to be an error output that amounts to not being able to connect to the sound device. As nightingale is what I currently have installed, the error output is such when I attempt to play any sort of media.
Configured audiosink audiosink-bin is not working.
I am using E17 after formerly having used KDE however I had similar problems with the initial install that were fixed after setting the default device in alsamixer.

Every thing seems to be loaded correctly and speakertest -c 2 seems to be working. The problem I had last time was with flash blocking sound output from other programs, but this problem subsided after having correctly set my default with alsamixer. I began to have the problem of flash blocking other applications from outputting sound when a browser was open a couple of days ago, but this has somehow progressed to any media application failing to output sound at anytime regardless if a browser has been opened or not. I uninstalled flashplugin and now rely on the plugin packaged within chrome but the problem persists. Any suggestions? I have read the wiki on alsa and on the flash plugin and have searched around but have found nothing that addresses my problem or that I have not already implemented or tried.
EDIT: It seems that I have gotten vlc to start working again. The issue here seems to be that /etc/alsa.conf had been marked by pacman as /etc/alsa.conf.pacorig and renaming it and setting vlc to output directly to the default device instead of having set to default has gotten sound working for it again. It seems the only problem that remains and I have gotten this error is other applications and it is probably the problem behind XBMC not playing audio but the audiosink-bin is not working error is most likely the source of the additional problems. I will look into it and see if I get any reply in the meantime.
EDIT: Due to something beyond my intelligence it seems that nightingale now plays sound and can even do so with chrome and a youtube video open. I am guessing the problem lied in the gstreamer plugins and when I removed all of my orphaned dependencies that may have been what had done it, something may have been in conflict or maybe just from the couple of reboots I have had since then. I did reinstall the plugins but there was a package that was removed called smpeg and another called sdlmixer those may have had something to do with it. So the moral of this story is to remove orphans on a regular basis, which I have been doing but just got around to today. If anyone has any input, which I doubt at this point. I will mark this as solved

I fixed it (for now, at least!)
I ran the below command:

Basically, my USB webcam, which also acts as a microphone, was being treated as my default sound card. I changed this by creating a file in /etc/modprobe.d with the following:
options snd-hda-intel index=0
Which set my real sound card as default:

The problem isn't ENTIRELY fixed. Skype's still being a bit buggy, but at least Chromium is now playing sound, including in Flash media. Strangely enough, after playing a Flash video (e.g. on YouTube), Skype's sound seems to fix itself if it's defunct.

["SOLVED"] PulseAudio - some applications won't output sound sometimes

So, I have KDE 4 and PulseAudio installed, with VLC as Phonon's backend software.
After startup, I often find that Skype won't output sound at all for seemingly random periods of time. This also often happens (sometimes simultaneously, but not necessarily) to Chromium. Pavucontrol and the KDE audio mixer, don't show anything useful at all in terms of the output of Skype and Chromium, and messing with master output in Pavucontrol doesn't affect anything.
After a completely random period of time (usually a very long period of time), these applications start outputting sound again. It's very frustrating, and restarting the applications doesn't help whatsoever. While these two applications are affected, all other applications output sound perfectly.
I don't even know. I've searched, but I haven't found any similar problems documented elsewhere. Any advice?
EDIT: Solved, for now.

I cannot hear any songs or movies from my laptop speakers - the headphone port works and a red light is showing? The output sound settings are showing as digital optical only? Any ideas :)

I cannot hear any songs or movies from my laptop speakers - the headphone port works and a red light is showing from the port? The output sound settings are showing as digital optical only? I used the headphones in the laptop for the first time yesterday and have had this problem ever since. Any ideas

The internal switch in the audio output port is stuck. Try inserting the earphone plug a few times. If no success, try jiggling a tooth pick inside in order to trip the switch.. If still no success, have the technicians at the Apple store genius bar do it for you.

Labview Synthesiser: Problem outputting sound via MacBook soundcard

Hi all!
First time posting here, hopefully i'm in the right section of the forum. Anyway, i'm a part time student and currently studying a module on Labview in university. As a mini project i decided to build a synth using Labview. I've it mostly built but i'm having a bit of trouble outputting sound to the soundcard. I'm also having a bit of trouble getting the waveforms to play for a longer time period.
I was sort of copying the setup of one of the example VIs (generating sound vi i think) and another vi i found online but i can't seem to get mine to work using my synth design. I've two problems, one is that the waveform only plays for a very short time but the main problem is that i'm getting an error (error 4803) saying the soundcard cannot accomodate the specified configuration but as far as i can see my setup is more or less the same as the generating sound vi (which works on my fine macbook). Obviously i'm missing something so i decided to come on here and ask for help.
I'm guessing the datatype connected to my sound output configure vi could be causing a problem since it has a red dot on the input terminal. Any suggestions on how i should fix this?
I've my vi attached. Any help would be appreciated!
Cheers!
Edit: I've already fixed the error 4803 problem. Had to change the input to the sound output configure sub vi. Now i just have to figure out how to get the sound to play for longer. Any ideas anyone?
Solved!

OK. You have several problems.
The cluster order in your Format cluster is Rate, Bits, Channels while the order in the "sound format" cluster on Sound Output Configure.vi is sample rate (S/s), number of channels, bits per sample. LabVIEW connects clusters according to the cluster order. How to avoid this: Pop up on the sound format conpane terminal on the Sound Output Configure.vi icon on the block diagram and choose Create Control. That will put a control with the same names and cluster order on the front panel. You can edit the names if you wish as long as you do not change the cluster order. The alternate is to Unbundle the data from your cluster control and then bundle it to the input cluster. I show this in the modification of your VI attached.
The VI does not respond to the Stop button until the event structure executes, which only happens when a key is pressed. Fix: Add an event case for the Stop Value Changed event. I show this in the modification of your VI attached.
The VI does not recognize changes in Octave, Amplitude, Osc Select, or Filter Frequency until the second keypress after changing any of these controls. Why? Dataflow. Those controls are probably read within microseconds after an iteration of the for loop starts. They are not read again until the next iteration regardless of when or how many times they are changed. The loop will not iterate until the Event structure completes, which only happens when a key is pressed. The Fix: Event cases for Value Changes on those controls. Note that this does not work because now there is no defined frequency. So, you also need some shift registers. Because of the problems mentioned, I did not put this into the modified VI.
Next, the event structure freezes the front panel until the code inside has completed. This becomes quite apparent when you set the duration to 2 seconds and press several keys quickly. The fix to this and the problem in the paragraph above is a parallel loop archtitecture, such as the Producer/Consumer Design Pattern.
Not a problem but a different way of doing something: Use Scale by Power of 2 from the Numeric palette in place of the case structure connected to Octave. I show this in the modification of your VI attached.
Now to your question about tone duration: The duration of a signal generated by the Sine Waveform.vi and the others is determined by the sampling frequency and the number of samples. You are a student so you can do the math. You need to adjust the number of samples because the sampling frequency is fixed.
The modified VI works fine on my iMac.

Output sound to multiple devices without delay

Hi there
I'm using Audio MIDI Setup on my 27" iMac running Mavericks to ouput sound to 2 devices (both iMac speakers and a Big Jambox, a bluetooth speaker), it works but with some latency. I tried drif correction in Audio MIDI Setup but doesn't change a thing.
How can I output sound to multiple devices without the latency issue ? I'm pretty sure that's possible. Maybe with a 3rd party software?
Thanks

I am not sure how I would do this if I am using Airplay as one output and hard plug for Computer speakers as the second output. The bosie system is in another room (why airplay) and the computer speakers are in a different room. Thanks for the reply.

Change Output Sound Device

Is there anyway to change the output sound device in iTunes without going through System Preference?
I have an iMac with built-in Speakers, and a 5.1 Griffin Firewave over Firewire. I want my music to come through my external speakers but I don't need my system sounds to come through those, right now I can only change it through System preference and haven't found a way to divide them up.
This is do-able in the Apple DVD Player... any thoughts for this function in iTunes? Is there some place I can put this in a suggestion box if it's not already a function?

It is a great pity you are using Leopard. Up until Tiger there was a great little free app called Detour that let you assign separate audio channels for different apps. You could Google "Detour" and see if there is another utility that will work for Leopard?
There is also an app Soundflowerbed that lets you route the output from one program and port it into another. Unfortunately, those programs must have 'audio channel recognition' (not a technical term - I just mean that they must be able to take an input and deliver an output, e.g. like GarageBand). iTunes doesn't.
