How to select default output device (microphone) in ALSA?

Hello,
My webcam microphone does not work.
It is not set in ALSA, and pulseaudio points back to ALSA. As a consequence, skype doesn't work.
I have read a bunch of wiki and manpages, found no answer. https://wiki.archlinux.org/index.php/ALSA#Configuration
Hence, how do I set usb webcam microphone as the default input device in ALSA? It is set by alsamixer, but
$ arecord -d 5 test-mic.wav
$ aplay test-mic.wav
produces nothing except files.
I've installed archlinux only because OpenBSD doesn't support skype. That's what I need from archlinux for.
I appreciate your answers and thank in advance.

To use arecord with your webcam you need to know and specify the device:
arecord -l; # Look for your usb device
arecord -D hw:X,Y # where X is the card number and Y the device number
As for skype, it should have some configuration options.
I know the device. I can see it by various commands. I know for various config options. That's now what I'm asking.
I am asking how to specify it. Where is the config file for ALSA? Is it input or output device?

How to set a default output device for FAX outputs

Hi Experts,
Business requires to set a default output device for fax outputs ( Medium as 2 Fax medium ).
as fas as print output ( medium as 1 print medium ) is considered we can maintain output device in condition record--> communication
I tried maintaining output device in VP01 for my condition type based on sales org but it did not worked.
Can you please suggest ways to achieve default output device for fax outputs.
Thanks,

Well, obvious solution would be to either update user profiles or change the output from 'process immediately' to 'process by a background job'. Then create a generic user ID with any fax number desired and use that user ID to process the output through the background job.
This is not really an SD question, so if this simple option doesn't work for you, I'd suggest to discuss other custom solution with your ABAP / Basis team.

How to redirect built in mic to default output device

Is there a program i can get that will take my voice from the default input device (built-in mic) and redirect the audio to the default output device?
Note: i do not want to record my audio.
Thanks for your time.

Ask Microsoft.... I'm not kidding either. This is a mac forum. You could try to be more specific but, I really don't know if anyone will have an answer.

Default output device not coming

I made one PDF form and attached it in List LG01 in CB85 to print process order through COR2 output device is mentioned as LP01 in list Lg01, but while printing, output device is coming as which is mentioned in user profile.
I want that output device which i mentioned in configuration should come as default during printing through COR2....Pl. help
Edited by: lisa harley on Feb 26, 2010 11:09 AM

Hello,
Please check the below settings at "Printer Specification" for CB85,
If output device = 1 ,then it will select the output device for user profile
if output device = 2 , Output device from configuration, ie CB85

Default output device for smartform

Hi all
how can we assign a default output device to a smart form so that the every time we execute a smartform it doesnt ask for a output device?
thanks in advance....

Hi
First see what your default out put device is.
That you can see in SU3>Default>OutputDevice.
Suppose it is set as 'PRINTER' .
Then in ur print program you have to write the logic as below.
CALL FUNCTION 'SSF_FUNCTION_MODULE_NAME'

Settings to set default Output Device in FPCJ

Hi,
System is taking LP01 as default Output Device instead of the custom made Output device(ZLOCL) while executing the Z smartforms using transaction FPCJ.
In user setting I have defaulted ZLOCL as default output device & desired page format type is also assigned to the smartforms.
Is there any other system/config setting to be done to make ZLOCL as default.
Please advice.
Thanks in advance
Sunil

Sunil,
Check your user profile using tcode SU3 and make sure you do not have LP01 there as your default OutputDevice. If you have it then your printing jobs will default on that.
I hope this helps you.

The device is in use by another process - error - cannot select Multi Output Device - Mac OSX 10.8.2

Dear Adobe Users!
Please help!
I'm using Adobe Audition CS5.5 on a Mac - OSX 10.8.2 (latest version of Mountain Lion) and I'm trying to select a Multi-Output device.
This was working FINE last few days - today, I get an error. I've tried to re-install Adobe Audition and that hasn't fixed the problem. When it first started up it said it couldn't find any audio devices at all.
Please can you help? I'm getting a message saying the device is being used by another process - but it's not being used by anything else at all!
Hope you are able to help! I use the multi output device option so I can record what I can hear. I spent two days trying to sort that out after it all-of-a-sudden didn't work last Thursday.
Now just spent last two hours trying to get Adobe to recognise the Multi Output device - it's been working fine last few days!
Many thanks if you're able to help!
- Rory

Durin,
May have sussed it! It seems that Built-in output was the way to have it for Audition CS5.5 to record what I'm hearing! Yes, the multi-device needs to be used - but in another settings.
Here's how I have each section configured and it now works!
First of all, in Audition > Preferences > Audio Hardware:-
Then, on the Mac's OS - System Preferences > Sounds (input settings)
Then Output settings :-
Then Midi Settings found in Finder > Applications > Utilities > Audio MIDI set up
All now seems to be working! I'll let you know if anything further happens!
I was certain I had the output device as Multi Device Output on Adobe before, perhaps it should've been set to Built-in Audio all along. Anyway, I re-installed my Mac from Time Machine, logged in as another user and it worked under that profile, then logged back in as me - and am using the settings in the pics above and all seems to be working!
It's been a long week, perhaps I was just going around in circles and didn't actually test these particular settings yesterday in this order after all.
Thanks again for your help! Sorry if I've caused any confusion!

Selecting audio output device in iTunes.

I currently have two sound cards installed.
My computer is defaulting to playing sound through one of them, but I would like to play iTunes through the other.
Is there a way to select the audio output device that iTunes outputs to?
I have no been able to find the option anywhere.
Thanks!

Hi
What program are you refering to ?? Or do you mean you have deleted the driver for your Audio/output device ??

How to change default audio device for gnome?

My laptop has an integrated sound card, but I lately got a USB headset (headphones+mic, which works with linux btw, I tested it with GizmoProject which lets me choose which /dev/dspXX I want): http://www.geeks.com/details.asp?invtid=U200&cpc=SCH
So, how do I change the default audio device for *all* desktop sounds to the headphones? I tried the two gnome sound properties, and when I select the headset device they let me configure it but ALSA still uses the internal audio card. Why isn't there a way to easily select which device you want for your sounds as there is for BeOS, Windows and OSX?

Eugenia wrote:Well, it's still not good enough.
We can't satisfy everyone. What you want is a corner case. For most people ALSA and dmix works appropriately, and that is what esd uses by default. We cannot document and automate every configuration possible. That's up to the users.
However, if you don't want to restart gnome, try the below... I make a few assumptions, but even if they're wrong, they're hardly difficult to work around.
Just copy the /etc/esd.conf to ~/.esd.conf, make your change, then do killall esd. Presumably gnome will restart esd, and it ought to read your local config. If it doesnt, start it yourself.
Feel free to write a script that automates this, or document it on the wiki.
I have to restart Gnome to get this thing working. Other OSes *automatically* can use an alternative device. But if I change ESD, I will have to restart Gnome, no?
Well, if you try my suggestion above, no. You can restart esd yourself. And that's what all the other distros do, except with some fancy GUI.

How to chang audio-output-device(s) in Windwos 8

Hi,
currently I’m working on an application that starts by changing the audio-output-device and ends with re-setting the old one.
On Windows XP I do this by changing the Registry-entry “Sound-Mapper” and it works quite well.
I hopefully assume it works on all Windows Systems from XP to Windows 7.
The background is that our program is supposed to play certain multi-channel sounds over an external USB-multichannel-soundcard and it should switch to that device on start. To actually play the sounds we use the AxWindowsMediaPlayer-Class
to integrate the Windows-Media-Player in our application.
However, on Windows 8, it is possible to set multiple Audio-Outputs and the Windows-Media-player has a setting to choose from them (under Options). I was unable to use the Registry-trick to switch the output-device and I could not find
a way to programmatically tell the AxWindowsMediaPlayer to choose the USB-soundcard as an output.
Is there a Way to programmatically(c#) ether change the audio-output-device(s) in Windos8 or to tell
AxWindowsMediaPlayer to use a certain device?
Thank you.

Hi Kristin,
I think your reply pushed me in the right direction.
The waveOutOpen-function is part of the
winmm.dll-API and I think, that API is the solution to my Problem.
Unfortunately I am stuck at this point. I tried mciSendString and mciSendComand. Both are cappable of playing sound, but I am unable to change the output Device.
This is my c# code to open a WAV-File via mciSendCommand:
MCI_OPEN_PARMS open = new MCI_OPEN_PARMS();
open.wDeviceID = 0;//this is somehow ignored
open.lpstrDeviceType = Marshal.StringToHGlobalAnsi("waveaudio");
open.lpstrElementName = Marshal.StringToHGlobalAnsi(@"test.wav");
IntPtr ptr = Marshal.AllocHGlobal(Marshal.SizeOf(typeof(MCI_OPEN_PARMS)));
Marshal.StructureToPtr(open, ptr, false);
mciSendCommand(Convert.ToUInt32(textBox2.Text),
MCI_OPEN,
MCI_WAIT | MCI_OPEN_TYPE | MCI_OPEN_ELEMENT,
ptr);
Afterwards I use mciSendCommand to start the playing of the sound, which works fine, but no matter what I enter in the “open.wDeviceID”-Line, I always get sound over
the default output.
I use waveOutGetDevCaps to get the number and kind of the output-Devices and this works fine.
Regards, Marc

Default output device for ALV report

Dear friends,
Here there is a user requirement that he want print a particular ALV report in a
perticular output device. and want to fix that output device for that report instead of changing everytime.
Kindly suggest.
Regards,
Praveen Lobo

Hi,
This way system is expected to search for default printer. What I would recommend you to do is call transaction SP01 within the report and pass the initial screen parameter thru FM.
Hope this lead, help you solve your issue!

VB6 Using MCI Commands to Select MIDI Output Device for Playback in Windows 8.1

I have written a MIDI Player program in VB6 that uses the multimedia control. In Windows 8.1, I understand that midimapper is no longer available so the third party softwares which can set the output devices for MIDI do not work as they did for
Vista and Windows 7. I found this Microsoft example code that selects sound cards using MCI code and was able to modify the code to show me the MIDI output devices. In particular I need to output to a USB to MIDI cable. Can this code be modified
to do just the PLAY function for midi out to the USB to MIDI cable? I do not need the record side of the program. Here is the MS article number since I can not post the link to the the VB6 program: q182799
With a modified code to play midi, I can then pull the necessary code into my MIDI Player Program. Thank you for the help on this.

Allow user to select default sound device.

Currently Spotify defaults to using the default sound device under windows when launched, it would be neat if you could choose which sound device you want to use isntead in the options screen, Thanks

I really need this feature. I use multiple soundcards to split outputs into different sets. For example. I do not want Spotify to playback using my headphones but my speakers while I play a game or anything else for that matter. I also tend to Stream some of my games and don't want Spotify to be recorded- This is the whole reason I had to set up another soundcard by the way.
Please, just add this small but essencial feature like any other Audio related product.
