How to set default audio device for java apps on Linux?

I would like to find a way to choose a particular (ALSA) audio device for java applications. How can this be done without reprogramming the application or changing the default ALSA device? I came across "sound.properties", but could not find any information how to use this file on an ALSA system.
Thanks for any help, Mark

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 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?

How to set default number format for whole app

Hi!
I have a bunch of View Objects and I have to set the format for each attribute of type number. I've tried using
MyAtt_FMT_FORMAT=#,##0.00
MaAtt_FMT_FORMATTER=oracle.jbo.format.DefaultNumberFormatter
on just a couple of attributes and it works OK. But since I have a lot of number fields across application in a lots of view objects, I would like to set this format as default for all the number fields in my application.
Can I do that and if yes, how?
Thanks

you can use Domains.

Set default audio device?

Prior to installing OSX Yosemite, the system audio output would be automatically switched to my USB audio device as soon as it was plugged in and detected by the OS. In Yosemite, I have to manually switch the output from Internal Speakers to the USB device.
Is there a way to force the setting to change on its own, as it did before?

Hello
I do not want to hard wire the Ipod HIFI. I understand that if I used the line out feature the system would recognize the device. I would like the system to recognize a remote speaker connected by wireless network and to accept this remote speaker as the default audio device. Not likely but should be an option.

Can you use different audio devices for different apps?

I've paired my iMac with a set of Bose Companion 20's - they connect via the headphone socket. I regard these as my default audio device. However, when I work from home I need to use Lync 2011 for Mac and want to be able to use a bluetooth headset for lync enterprise voice calls (my employers chosen platform). Is it possible to use my bluetooth headset for incoming / outgoing calls when using Lync but the Bose speakers for say internet radio? If this is possible, any guidance as how to configure would be much appreciated. Thanks in advance....

After going to a particular folder and selecting a view, click the little Action Gear and select "Show View Options" and at the top check the box "Always open in xxx view" where xxx will be the view you presently have selected.
Do not check the bottom box to use this as a default or else all folders will then open this way.

[SOLVED]How to set default audio playback device?

I have an X-fi forte soundcard that doesn't work on linux, so I'm just gonna use the onboard realtek chip, but I get no sound from that either unless I physically remove the X-fi card.
I use the X-fi when I boot into windows though, so I'd like to keep it...
How do I change the default playback device?
I didn't find anything that worked in the wiki or with google.

oh wait... I just spotted this in the wiki guide, a little too late
NB: Some modules do not support indexing options eg. snd-hda-intel. If you experience problems on reboot edit /etc/modprobe.d/modprobe.conf to just have the modules.
what does that mean "edit /etc/modprobe.d/modprobe.conf to just have the modules.".... what modules? :S
should I just remove "index=0" from the line?
Edit: yes I should. It's working
Thx man

Set default audio track for playback in Source monitor

So I'm an editor that is somewhat new to the profession and I am working on a project right now with close to 100 video clips in my project. Most of the clips have their audio recorded to track 2 but when I load the clips into the source window to find the footage asked for in my script there is no audio playback.
They play fine in the program monitor once placed in a timeline, because I have all the audio tracks are turned on until I do my mastering at the end of the project. To get audio playback in the source monitor I have to change the view option to audio waveform which shows a blank screen because there is no audio on track. I then go to the drop-down menu just below the video display and select track 2 at which point the audio waveform shows up and plays back fine. This isn't too arduous a process and isn't a great burden but it slows my workflow down considerably as I have to repeat the process for each new clip I load into the source monitor.
My question then is if there is anywhere in Premiere that I can set which audio track is the default audio playback track for clips loaded in the source monitor. I work on a lot of similar projects like this for the same client and they don't have the most rigorous standards for their shooters. This problem has come up before and will most assuredly arise again in the future so any tips/advice on how to fix this on my end would be much appreciated.
Thanks!

I'm not really sure.I don't do any shooting for the client and in fact don't have any contact with the shooters, we just do the post. They use a number of different freelance videographers all of whom have different equipment and procedures when it comes to formatting, orginization, etc.

Setting default volume level for Java Desktop

Hello,
I am running Sol 10 11/06 for sparc. How do I permanently set the default volume level for the Java desktop? If I change the volume manually and "save settings" on logoff, the saved setting is not saved after a reboot, after which I have to set it again.
Thank you......

Annoying, isn't it?
Unfortunately the only thing you can do is lower your system volume before opening those pages. The volume could be controlled by the Web page author but most are clueless.

How to Set Default Printer Just for Safari

I use 2 printers.
One prints paper docs etc. The other prints labels only. When i want to print the labels I have to select that printer in the print dialogue in Safari every time. Super annoying.

How to set default email address for contact with multiple addresses.

Apologies if this has been asked before, it seems a very basic question but I'm unable to find an answer.
Can a default address be set in Address Book for a contact with multiple addresses? Or if not, which address does it send to "automatically" when this condition exists? I know you can manually select the address you want to use, but what if the contact is added to a group?
Thanks
Denis

Thanks for the reply, buy I have no idea what this means.
I have the same question. I have a contact that has five email addresses. When I add the person to a group, Mail automatically selects one of the addresses, but not the one I want. I need to go back and manually select the correct address. Can't I select one of these addresses as the default to be used all the time?
Apologies for not quite understanding the first reply.

How to set default file permissions for applicatio...

I have the nokia n86 and was wondering if there was any way of setting the file permissions of a program via the phone. To put it in context, i downloaded a program that edits photos but everytime i try to load a picture from my phone it asks me (for every single folder in my phone, not just the photo ones) if the program can open it. I can be there clicking yes all day as i there is a lot of folders and subfolders on the phone. I know sony ericssons had an option where you could select the programs permissions to always ask or never ask but i cant seem to find a similar option on the nokia.
Does anyone have any ideas?

Same issue here. Everything I put on the drive is set to Read-only for the group.

How to set flex builder profiler for AIR apps ?

Hi everybody !
I am trying to profile my AIR app but I can't run the profiler....
For flex app (in web browser) profiler works fine, for my AIR app, debug works but profiler just display 'socket timeout'.
I also try to profile my air app as an external application profiler start but crash saying NativeWindow not found (like AIR sdk was not found...)
SO How I can't set my AIR player or my profiler to work ???
Thx all and happy christmas !

Hello,
I would be glad if someone show me how to accomplish those. I am new to Java so I am not sure how to do those.
Best Regards.
1. create a batch file to launch your 'desktop' app - the batch file should set the proper environment (JAVA_HOME,, path, etc)
2. create a small wrapper application that is launched by Java web start.
3. the wrapper app will do nothing more use ProcessBuilder to execute the batch file you created which will then launch the app
That way Java web start can use 1.7 to launch the wrapper app but the batch file will set the environment to 1.5 for the other app.

How to set my own icon for java frame ??

I create a java class it extends JFrame. I want to change default icon on the left_top corner and using my own icon. It is a --.gif file. How to do it. When I try to modify it using setIconImage( Image image), I met problem. I cann't new Image("--.gif"). I don't know how to create a Image object using a string(file name). I try to use ImageIcon , but it is not image obj. Thanks. Gary

According to the documentation setIconImage does the following: Sets the image to be displayed in the minimized icon for this frame. Not all platforms support the concept of minimizing a window.
So,
1) It does not change the icon in the top-left corner
2) It does not work on all platforms.
