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?

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 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

How to change default action "alarm" for all signatures ?

My question belongs to a Cisco 1712 (128 MB, IOS 12.3T, SDM 2.5 installed):
I'm trying to change the default action "alarm" to "alarm,reset,drop" for all signatures of my custom set.
However doing so via SDM fails. First, it appears as being done correctly, but after compiling the signatures again, the default values are back there (in the same sense, I was unable to delete signatures, works just using the CLI).
I followed the instructions at cisco.com:
router(config)#ip ips signature-definition
router(config-sigdef)#signature 6130 10
router(config-sigdef-sig)#engine
router(config-sigdef-sig-engine)#event-action produce-alert
router(config-sigdef-sig-engine)#event-action deny-packet-inline
router(config-sigdef-sig-engine)#event-action reset-tcp-connection
router(config-sigdef-sig-engine)#exit
However ip ips signature-definition is not understood by the router, so the procedure fails.
Can you please assist me ?

You can use IOS command-line interface (CLI) to change signature actions for one signature or a group of signatures based on signature categories. The following example shows how to change signature action to alert, drop and reset for signature 6130 with subsig ID of 10.
router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#ip ips signature-definition
router(config-sigdef)#signature 6130 10
router(config-sigdef-sig)#engine
router(config-sigdef-sig-engine)#event-action produce-alert
router(config-sigdef-sig-engine)#event-action deny-packet-inline
router(config-sigdef-sig-engine)#event-action reset-tcp-connection
router(config-sigdef-sig-engine)#exit
router(config-sigdef-sig)#exit
router(config-sigdef)#exit
Do you want to accept these changes? [confirm]y

How to change default response encoding for not jsp files

Hi
Question about Weblogic Portal&Serwer 10.
For standard web applications from war archiwes, html etc. files are send with default server response
"Content-Type: text/html; charset=ISO-8859-1".
The question is how to disable this default header
or how to change this header to correct encoding.
PS.
I found solution only for ear' applications ...
with file META-INF/weblogic-application.xml and webapp.encoding.default parameter. This works well for ear's.

Thanks. I feel a bit like a dummy for not seeing that but so it goes. What I was looking for, in a perfect world, was to set a preference to permanently sert a default folder on an external drive to store the .dvdproj files once they are made.......but your suggestion is close enough to my original intention.
Thanks again.

How can I change default audio peripheral for Flash Player ?

Hello,
I want to stream music from youtube vidéo to my TeamSpeak3 Client. For now I use VB-Audio Virtual Cable to spread my music with VLC. But the problem is that i can change output peripheral for VLC, but i can't find this option for Adobe Flash Player.

How to Change Default Iview Properties for Role Upload?

Hello,
We have many roles to upload from R/3 ABAp system to NW2004s EP.
We use the Role Upload tool in the Portal to achieve this.
It works fine, the roles are created in the portal and can be assigned to users.
The fall back is that we have to modify every single transaction iview in the portal after the upload to modify the SAP GuiType from "SAP GUI for HTML" to "SAP GUI For Windows".
How can we change the default model used of SAP GuiType for uploading transaction iviews in uploaded roles?
Also, the uploaded role is not flaged as an "Entry Point", is there a way to set this marker to "Yes" as a default value for all uploaded roles?
Best regards.

This is one of Acrobat's less intuitive areas!
For defaults, right-click on the text box that is as you want it: then select menu item 'Make current properties default'
Use Ctrl-E to bring up the Properties toolbar: its content will change depending on whether you have the box or the text selected, and selecting the box or text can be a bit clunky.

How to change Default document size for CC Library Graphics (InDesign)

Good morning --
I have just discovered the amazing uses of the CC Library setup in InDesign and would love to be able to use it as a tool to collaborate template galleries amongst coworkers.
I work in an industry that offers many different templates for our Marketing pieces available to the sales team. What we have in place right now is about 50+ different templates in their own packaged files. Now, this isn't all that difficult to maneuver around, but the CC Library has made it so I can "drag and drop" templates into place. This drag & drop feature is easy enough for me to grasp, and with the proper training it should be with the rest of the team (should being the keyword). However, in some cases if you double-click on Library graphic it opens the file in it's own editable file with a custom document size of 8.5x11 Portrait (which I imagine to be the internal InDesign preset).
My questions therefore are when I double click on the library "Graphics" can the document size be anything other than 8.5x11? Can each Graphic have it's own document preset?
- If I open a file that is set for landscape, all of the "Graphic" falls off of the spread.
- Some "eblasts" are much longer than 8.5x11 (sometimes as much as 8.5x20), thus knocking some of the "Graphics" into that weird space area.
Please let me know if I am not being a clear enough.
Thank you!
Steve

@Steve – you are totally clear what you are doing and what you like to do.
But I fear an automatic setting that is creating the page size according to an asset's size does not exist right now.
I can change the size of a new document beforehand, if no document is open and create a new size in the document's properties dialog with the keyboard shortcut alt + cmd + p (in my German InDesign on Mac OSX 10.7.5). But you have to know in advance what size that should be.
Example: If I chose A3 instead of A4 (my default) when no document is open and double click an asset in a CC Library the asset will be placed in a one page document sized A3.

How To Change Default Expiration Date for Portal User in Linux and Windows?

Hello,

2. Oracle Application Server 10g Release 2 (10.1.2) Enterprise Edition on Linux
I heard the portal and orcladmin user passwords will expire in about 60 days. I want to prevent this from happening. How can I set the expiration date to never expire for both these users? Or at least give me some warning?
I heard that you can do this through the Oracle Directory Manager. However, I am unsure as which server to enter on the field. I've used the following:
<servername>.hostname.com/389
<DBname>.hostname.com/389
They say 389 is the default port. Since I did not really
Does anyone have any ideas?

You have the answer in yours hands:
Search for "60 days" in the forum

for instance.
For the servername, it's the name of your server and the port is depending of your platform (have a look to $ORACLE_HOME_INFRA/install/portlist.ini) and

How to change default memory storage for music in ...

i want the memory card to be default in the phone, so that i can just put all my music on it and forget about it. at the moment i use ovi player but this just puts it on the mass media memory, therefore filling it up quickly. is there a setting in either the phone or the application to put memory card as default?

There are some serious flaws in the Nokia software when it comes to saving your music to your phone's memory card instead of the mass storage area.
I have an N8 with a 32GB MicroSD card and I keep all my music there. It totals over 18GB at the moment so it won't fit on the mass storage area (16GB) no matter how much the Nokia software might want to put it there. This is how I get around the dilemma:
Nokia Music Player is what I use to handle my music collection. However, I don't use it to transfer the music to my phone because it will only copy it to the mass storage area. You can not configure Nokia Music Player to transfer to the MicroSD card so you can stop trying!
Nokia Suite on the other hand can be configured to save to your phone's MicroSD card and happily, it reads and respects the music library that Nokia Music Player has prepared. Unfortunately, Nokia Suite has very limited abilities when it comes to managing your music. It can't sort out the album art for example.
So you will need to use both programs, Nokia Music Player to manager and prepare your music library complete with embedded and optimised album art, and Nokia Suite to tranfer it to the MicroSD card on your phone once it's all ready to go.
Alternatively, you can connect your phone to you PC and treat it like a disk drive, copying all the MP3 files over manually. That's what a lot of people do because the Nokia software is awkward to say the least.

How to change default alarm sound for events

I remember initially when setting up ical, it gave an option to set a default sound for messages. I want to change the sound, but cannot find the option to do so. currently when creating a nerw event, the message with sound option shows up with the default sound (Basso) that I selected initially. And I have to change it manually every time a new event is created. Is there a way to change the default sound?

Settings > Sounds > Calendar. Maybe it was inaudible because yoursound was not turned up.

How to change default number format for saved data in signalexpress

I cannot find an option for determining format and precision of saved data. By default it is scientific with i think 3 siginificant numbers. How and where to do it?

Stjepan, it sounds like you're right where I was 2 months ago! Glad to see I'm not the only one struggling w/ SE.
Here's what I've had to do to control the precision of the data in my ascii file.
Insert an Amplitudes and Levels step from Analysis>Time Domain Measurements.
In the A&L settings, deselect Export RMA Value (keep Export DC Value selected).
Now drag that DC signal from the A&L step into your data view (literally drag and drop this signal onto the graph). From here you can configure the data view's properties to your likings, I.E, significant digits or digits of precision, floating point, etc.
I've found that Floating Point, 2 Significant Digits, and uncheck Hide Trailing Zeros to work well (visually speaking).
Insert your Save to ASCII step after the A&L step, and be sure to save your A&L's DC signal.
The data will export exactly as it's shown in the display.
TIP: you can rename your signals from any of the steps. This is handy because it's the renamed channel names that show up in your data headers (much more descriptive when you have multiple channels).
My apologies if this is all information you already know...

My Ipad 2 external speakers does not work and headphones has popping sound. This all occured at the same time as my Iphone and Ipod headphones only played mono (no, the "mono" option is not on). How can there be audio issue for all these devices?

My IPad 2 external speaker does not work and the original headphones have popping sound when used. This all occurred at the same time as my IPhone and IPod headphones only plays mono (and no, the "mono" option is not on) with the original headphones, as well as, other headphones tested. How can there be audio issue for all these devices at the same time?
As you may have noted from the list of Apple devices I own, I believed in the Apple and the products it was producing; but it is hard to believe from my experience and the other voices within the Apple Community that we are all experiencing the same hardware issues. Especially since I recently, I upgraded to an IPhone 4g (no, my faith in IPhone 5 series is very little) and is experiencing the same audio problem as described above. So now, I am off to the Apple store again to be told that it’s a hardware problem on new IPhone. Really? Apple, what happen to the pride in the product you were producing?

Everyone does things a little differently. I love to "jam " along with iTunes ( or old Lp's) . Always have. That's where/how I've learned to play .
I'm sure leonieDF is giving a proper way to jam along on a keyboard with an iTune. He blows my mind all the time with what he knows. Nuff respects to him !
What I do is make a GB project I call "Jam With". I'll make several new tracks that are blank. Just has a few instruments named in the blank tracks. You can change those per song ...
Because I'm not concerned about changing the pitch / key.... of the iTune or the tempo ... I can simply play along with it.
Peace,
P. Dreadie

Where is the registry key for the default audio device in Windows 7?

Win 7 only allows playback out of one device (ie front or back audio jack) at a time. If you have something plugged in to both at the same time, it will only play out of the one that is set to be the default audio device. This can be changed
in the 'Manage Audio Devices' window by selecting the the desired device from the Playback tab and clicking Set Default. What I would like to do, as it is very annoying to have to go here every time I want to switch between my headphones and speakers,
is write a script that will change which device is the default playback device, so if I push one of my extra keys on my keyboard it will change it to speakers, and if I push a different button, it will change it to headphones (or one button that will switch
to whichever one is not the default). I have a script currently that opens the window and simulates clicking the set default button, but it is not ideal as it has to actually open the window. I figure if I can just change whichever registry key
is storing the default playback device, it will work a lot better.

Once again, a clear cut case for it being ABSOLUTELY WRONG for anyone but the original poster to mark a question as answered.
I've tried 3 different machines of difference pedigrees (all x64 though) and none of them have that key.
DAS
The question is not about x64 machines, The answer was correct for the question. The question is closed. If you have a new question please start a new topic.
Please review the forum guidelines.
