Setting up audio input/output devices

I'm running AA3 with an Alesis USB 2.0 mixer attached to my computer. I want the mixer to act as my audio input device, and the computer's soundcard to act as the output. Now, when using AA1.5, I could simply set the audio input device as the USB mixer, and the output device as the soundcard, and I could record and playback without any issue. However, when I go to set the mixer as my input device, AA3 also seems to want to make this my output device. I do not want the mixer to act as the output, I want all output to go through the soundcard. How can I make this distinction in AA3? Let me know if you need more information, I'll be happy to provide it.
Cheers!
Sean

>So, while working in AA1.5, I'd arm a track for recording, hit record, and it would record the sound source I plugged into the mixer. Then I'd hit play, and it would play what I just recorded through my speakers, which are hooked into my soundcard. Then, I'd arm a different track for recording, and once I hit record, I would hear the track I'd just recorded playing through my speakers, while recording a new track, which was being brought in through the mixer. I'm still not entirely clear on why this isn't possible in AA3, or if it is, and I'm just missing something.
That's a different issue. And it's perfectly possible in 3.0, assuming that you have your sound device set up correctly to use ASIO, and Audition's input and output assignments set to use what's available in it. In fact there are more options in 2.0 and 3.0, because if you use the ASIO driver directly, you can use real-time monitoring
through Audition rather than through the mixer direct path (which is the usual way). The advantage is that you can add channel effects like reverb to the monitor mix, which often helps singers. This only applies to the monitor feed though - what's actually recorded is 'dry', so you still have all of the effects options available afterwards. To use this mode set the monitoring to 'Audition Mix'.
But however you look at it, the overall monitoring situation works fine - or believe me, just about every user going would have complained about it by now!
So, you can't really compare AA1.5 and 3.0 from a monitoring point of view - the ASIO situation makes them look somewhat different. 1.5 effectively ignores monitoring - it just uses the Windows APIs and DLLs to record, which is essentially what's provided by the operating system. And that's why it works with any sound device that the OS recognises. But with 2.0 and 3.0 you are entirely reliant on a system that bypasses most of the OS in order to work faster (lower latency).
One of the snags with this is that a lot of sound device providers that aren't producing what might be described as 'pro' devices - in other words the providers of on-board sound chips, and a few more besides - don't always provide anything like an acceptable ASIO driver for their devices, and that's why ASIO4ALL was developed.

Utility to switch between Bluetooth headset and built-in audio input/output

I'm looking for a utility that will switch the Sound preference settings between my Mac's built-in audio input/output device and my Bluetooth headset for use with applications such as Skype.
The way I envision it working is that I would click an icon at the top of the screen and it would toggle the Sound preferences settings from
Output = Line Out (or Digital Out)
Input = Line In (or Digital In)
to
Output = (my Bluetooth headset)
Input = (my Bluetooth headset)
or vice-versa.
That's it. It doesn't need to automatically detect my headset as I might be using the headset on another device. Just a button that would toggle between the built-in and Bluetooth device settings.
Has anyone seen anything like this?

Thanks, it works great.
It would be even better if one could define device groups. e.g. Headset, built-in devices, etc. I'll drop a note to the developer.

Can I set the audio INPUT to my pre-amp, and audio OUTPUT to the built in?

I am using Logic Express 7. I want to set the audio input to my Firefox pre-amp, but set the audio output to my computer's built in speakers. I want to essentially record into the pre-amp and listen to the playback through my speakers. I can easily do this in GarageBand, but haven't found a way in Logic.

The remaining problem I'm having is when I record into an "Audio" track via my microphone which is plugged into the Firebox, I'm still only hearing the playback from the Firefox headphone jack, not the computer's built in speakers.
Did you select your new aggregate device in Logic's audio preferences? If so, then the problem is probably with your settings in the control panel which controls the Firebox - I don't use it, so I don't know what it's called, but it controls the routing and monitoring for the Firebox. Check the Firbox manual - there are probably two settings, one for playback and one for direct monitoring when tracking.

Audio Input Output on MacBook Pro 13 inch

I want to buy a MacBook Pro 13 inch but the problem is the audio input output port.
I usually need to use both jacks because in one I record my guitar and in the other I use my headphones.
Is it possible to get a splitter and to make from one jack, two, input and output or do I need to buy USB headphones?
A splitter would be the best solution

From the manual:
+"*Audio out port.* Connect external speakers, headphones (including iPhone), or digital audio equipment. You can specify audio analog line in functionality, to support line-level microphones and audio equipment, by selecting Audio In in the Sound pane of System Preferences."+
+"Choose Apple () > System Preferences, and open Sound preferences. Specify whether you want the port to be used for audio input or audio output."+
This means you must choose whether you want the single audio port on the 13" MBP to be input or output. It mentions iPhone headphones, but those will work only as headphones, not as a combined mic/headset when connected to the MBP.
(As in, "Oh, now I get it!")
Thinking on your comment, I see what you mean by 'an extra port' - the iMic has both in and out, meaning you'd actually have three counting the internal port on the MBP.
Looking back at your first post, you mention USB headphones. That would be fine as well - set the MBP's audio port to be used for input, and connect the USB headphones and use those for output. No 'extra' port that way, and USB headphones are cheaper than an iMic.
EDIT: The caveat there is that the audio in on the MBP (true for all MBPs, not just the 13") is a line-level input, not a microphone input. So, the MBP is expecting a line-level signal, meaning preamplified audio. If your guitar puts out a line-level signal or you're using a powered mic, fine. Else, you may need the iMic, which can take either line-level or microphone (non-preamplified) input.

After OS Upgrade, System Preferences won't recognize audio input/output.

When I got an iPhone, I had to upgrade to OS 10.5.8, as well as upgrade Safari (to 4.0.3) and iTunes (to 9.0.1) for everything to run smoothly, and it does.
However, since I went though the motions last week with these upgrades, System Preferences or Utilities doesn't want to recognize my audio input/output jacks. It won't recognize when I plug in my stereo or my headphones. I hook up my computer to my stereo all the time to listen to music in the living areas of my apartment, and now I can't because it isn't reading the jack.
Any suggestions? How can I get the system to fix this problem?

Check your Audio MIDI Setup settings.

Audio: no input - output devices macbook pro late 2011

My computer has no audio input or output devices anymore.
This problem appeared after I had used a software oscilloscope to test an amplifier. The amp was connected through the mic input. It worked for a couple of minutes and then the audio went mute. I'm suspecting, that the circuits took a hit although the input power wasn't excessive.
I have reinstalled the OS, restarted the coreaudio daemons, plugged-in / out a mini jack, reinitialized the audio preference files but all with no results. The audio is dead... as if the relative circuits where non existant .
The Apple hardware test doesn't seem to see the audio circuits and ends with a "all ok".
I'm left with the following questions :
Is there a hardware test for audio ? Is there a fuse / protection circuit for the audio circuit ?
Thank's for any ideas.
See sig. for hardware

Hi,
I have exactly the same problem and It happened in a similar situation.
Did you find a solution?
Thanks

Garageband Quits Every Time I Change Audio Input/Output

Hi. I own a Plantronics headset that came with MacSpeech Dictate when I bought that software a few years ago. It shows up on my Mac as a C-Media USB Audio device.
I'm trying to use it with Garageband. So, in Garageband, I've gone into Preferences and the Audio/MIDI section.
When I choose the C-Media USB Audo device as either "Audio Input" or "Audio Output" (I want to use the headset for both), Garageband asks if I want to "Change audio driver" and I then click yes. Then Garageband has a status bar saying "Initializing audio driver." Then, before it finishes initializing, Garageband quits. This happens every single time.
So, I'm not sure what to do. I don't even understand why Garageband is looking for a driver when my headset is a USB device that works with all programs -- it's not a MIDI keyboard.
Sometimes, after I restart Garagband after the quit, I see that it has changed the device. But this happens more frequently for the Audio Output Device. For instance, the C-Media device is now selected for Audio Output. But I keep selecting it for Audio Input as well and Garageband keeps quitting and when I restart it, the Audio Input device hasn't changed and still says Built-in Microphone.
I can't imagine I'm the only one who's had this problem. If anyone knows the solution, I'd appreciate it.
Thanks!

Thanks for the reply. it got me halfway there. Now it will open for the audio side, but still crashes as soon as I switch to Midi.
There were no Midi configs in my library, but there's a folder full of them in the main Library. Most of the files in there I don't care about, but there are several that I don't want to lose. Should i trash the folder and then re-install the ones I want?

Set several printers as output devices when scheduling a job

Hi experts,
I am working on ECC 6.0. I am scheduling background jobs through sm36 and I must configure 3 different printers as output devices, that is to say the output must go to 3 printers at the same time. I can not find how to do it. Could you please help me ?
many thanks,
Best regards,
Guislain Libessart

Hi,
I am really sorry, about those responses but it is possible. You will have to create a POOL printer for the same.
Goto SPAD
Create a New Printer with
Device type : It should be common for all those actual printer where the printing will happen.
Device Class : Device Pool
(When you set this Device Class It will open one more tab "Device Pool" and the tab "Acces Method" will no more be there)
Goto the "Device Pool" Tab Add the printers to which the print will redirected to. And choose the option "Send to All Devices in Pool".
Now assign this POOL printer to the background job from which you want to print the outout to all those printers.
Regards,
Sanujit

Setting value of input/output field of screen in abap program

I have a screen.I have added a input/output field in my screen.The purpose is i just want to display a text in that field upon PBO through my abap program.I m a newbie.PLS help me
Also can i use textfield instead of input/output field for this purpose.if so then wats the difference between both of them

Hi
To display a text in I/O element, go to the PBO of this screen and
assign the text to your I/O element.
Lets say if TEXT_IO is the name of ur UI element, and you want to display "Hello" into it, do it as follows:
TEXT_IO = 'Hello'.
Must ensure that the type of this UI element is CHAR type and you define its lenght properly.
to display "Hello", length would be 5.
Hope it will solve ur query.

Audio input/output issues

I just bought a Mac Book Pro and realized there is only one jack for both input/output. How do I record a guitar directly into Logic while still monitoring through headphones if there is only one jack for both?

there is a USB dongle for that, they sell them at Guitar Center or online for about $30

About the digital audio input/output

So, those accept optical digital audio, and what kind of other digital audio signals?, what kind of adapter i need to use this feature?, so it is compatible with any 5.1 audio system like home theathers etc?

so it is compatible with any 5.1 audio system like home theathers etc?
As long as the stereo has a digital optical audio input, yes.
The port is a "mini-Toslink" port so you'll need a mini-Toslink to Toslink adapter and then a standard digital optical audio cable (Toslink cable). Sometimes you can find a cable with one of each plug at either end.

[SOLVED] Switch all audio input/output to USB headset

Hi, I have a USB headset that I frequently plug/unplug from the computer. Is there a way to make it the default sound device when plugged, and automatically switch back to the motherboard's on-board audio device when unplugged?
Last edited by stavrakis (2012-04-26 15:57:56)

I have an Intel HDA 5.1 internal audio card, and a 5.1 USB headset, using the modules snd_hda_intel and snd_usb_audio respectively. The internal card is set as card 0, and the usb headset is set as card 1.
I'm using ALSA right now, but I wouldn't have a problem switching to Pulseaudio if it's easier.
EDIT: I used pulseaudio and solved it for applications that are not already playing sound (not shown on pavucontrol's Playback tab)
I created a udev rule, which executes a script when card1 is inserted, since I know it is the USB sound device:
SUBSYSTEM=="sound", KERNEL=="card1", ACTION=="change", RUN+="/home/stavros/bin/pulse-ins.sh"
This script (pulse-ins.sh) executes another script as the current user:
#!/bin/bash
su -c "/home/stavros/bin/pulse_insert_card.sh & exit" stavros
pulse_insert_card.sh contains the following:
#!/bin/bash
/usr/bin/pacmd set-default-sink alsa_output.usb-0d8c_USB_Sound_Device-00-Device.analog-surround-51
/usr/bin/pacmd set-default-source alsa_input.usb-0d8c_USB_Sound_Device-00-Device.analog-stereo
These 2 scripts and the udev rule automatically change pulseaudio's default output & mic input when the card is inserted. However, applications already playing music have to be switched manually through pavucontrol.
Sometimes, the card is incorrectly identified as "Analog Stereo Duplex", with no 5.1 option. In that case killing pulseaudio and letting it start again solves the problem.

Maybe check your settings in the following locations:

• Audio Midi Setup in Utilities folder
• Garage Band Preferenes (Audio/MIDI)

Audio input/output problems with Mac Mini

at first, my sound just stopped working all together and for some reason the monitor was getting no signal from the mac mini. i unplugged everything for a minute and plugged it back in and the monitor was working again, but still nothing with the sound. no sound coming out from even the internal speaker, and the audio in jack (which i use frequently) stopped working as well.
this is the really strange part: after tinkering around trying to fix the problem i realized the only sound that comes out it is from the internal speaker, but it only comes out when i have something connected to the headphones jack.
has anyone ever had a problem like this? i'm just trying to figure out if it is something i can take care of myself, or if i might need some repairs done.

OK, then two things to do.
First reset parameter RAM - it's an area of non-volatile memory used for system settings and hardware configuration. It it gets corrupted, it can cause odd problems.
Reset PRAM
-Shut down the computer.
-Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in the next step but one.
-Turn on the computer.
-Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
-Hold the keys down until the computer restarts and you hear the startup sound for the second time.
-Release the keys.
Next, perform an SMC reset. The SMC is the device which controls system hardware and devices, so if there is a problem with hardware components not functioning, it could be that.
To reset the SMC on an Intel mini:
-From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off).
-Unplug all cables from the computer, including the power cord and any display cables.
-Wait at least 15 seconds.
-Plug the power cord back in, making sure the power button is not being pressed at the time.
-Then reconnect your keyboard and mouse to the computer.
-Press the power button on the back to start up your computer.

Audio Input - Output

I am inputing a mixer/compressor signal to my Mac and want to be able to pass that signal through my system to my amp. Is this done through Garage Band or through the MIDI set-up? I also want to be able to record while simultaneously playing music. How is this possible?

Plug the headphone jack of the computer into the input on the amp, turn on Monitor for the track on which you are recording.
