WRT54GS V.1 and SOE Games , Voice Chat

After a few weeks of trying every method of troubleshooting.. the voice chat feature from SOE games still does not work when connected through my router. If I connect dsl modem directly to pc, the voice feature works.
This was their last recommendation, which btw I have updated firmware to the latest version already:
"Hello again,
From the results you've just shared it looks like your router is unable to send/receive VoIP data, because the packets are too large. In order to fix this, you will need to update your router's firmware, hopefully Linksys has a new firmware with a VoIP data fix to allow the router to process the larger data packets."
How can I verify the packet size being too large? Is this true?

Have you ever used the voice chat feature from SOE games when connected through the router ?
I doubt it...It seems there is no such firmware with a VOIP data fix...
Remember, after a firmware upgrade, you must reset the router to factory defaults, then setup the router again from scratch. If you have not done this since your last firmware upgrade, please do this now and see if it corrects your problem...
To reset the router press and hold the reset button for 30 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and re-connect the power cable...Now re-configure your router...

Voice chat issues in games

I try to voice chat with my head set in games and on steam voice chat they can hear me in steam voice chat but I cannot hear them. It is not the headset since I’ve tried many of them. Voice chat work with my account and headset fine on other computers. When
I voice call people I don't hear the ring of the call when I call them unlike I do in other computers but I can hear the sound in most games fine and I can hear the beep when someone messages me. I can see the in the voice chat their volume of how their speaking
go up and down the bar that show how loud they are speaking but I can’t hear them and the ringing when I call the in steam voice chat.
I have Windows 10 Enterprise Technical Preview build 10041

Hi,
Do you mean that you can hear others' voice, but all your friends can not hear you? Have you checked the volume mixer to adjust the volume of the video chat or check the volume settings on the game page? Are they all set in correct configuration?
When does this issue happen? recently? or since you installed 10041? I recommend you manually reinstall the driver for the headset and check if it works.
Regards.

Whiteboard-Voice Chat archiving

Hi,
I am developing an application which uses 2 applets in a single jsp page one as a whiteboard where we can draw and another a voice chat cum text chat application.
I need to save both the drwaing and the chat content in the database and retreive and show it to user which contains the drawing and the voice chat content in sync.
How can this be done?Please advice me.
Thanks
Ram

Hi,
Creator 2.0 does not have support to create Applet. You could use free tools like netbeans (http://www.netbeans.org) to create the applet and then import it in to Creator.

Free Voice Chat Code

Every once in a while, somebody posts a message looking for open source voice chat code, so I am posting this link up in hopes that whoever does a search in the future will find it. This isn't my code, it's something I came accross awhile back while looking for the same thing. It is an applet (also a non applet version). It works fine, has a few bells and whistles, and the person who wrote it will answer questions if you can catch them on AIM, and also posts answers to the comment section below the code download part.
This is the direct link:
http://www.planet-source-code.com/vb/scripts/ShowCode.asp?txtCodeId=4644&lngWId=2
If it doesn't work for any reason go to Planet Source Code (www.planet-source-code.com), and type in "voice chat" in their search bar, with "java & javascript" selected in the language selection menu.
Have fun.

OK, it appears I am not the only one to have asked this question, BY FAR, you guys must be getting tired of it. Sorry about that. I now searched the forum as I should have done before. I found:
http://java.sun.com/products/java-media/jmf/2.1.1/samples/samplecode.html
Is JMStudio what I should look at to learn it? Or is there a more basic voice chat program out there. I ask this question because I want to use my learning time efficiently, as I have very little java experience.

Multicast Voice Chat - Best Way To Handle (Multicast /w more than one broadcaster)

Hello. Currently I am working on a multicast voice chat application. I am a bit new to the multicast scene and I could really use some help with how to go about the next stage of coding.
The plan is to make an application that allows 5 (expandable later) users to connect to each other through stratus and communicate using voice chat streams. Right now, I have been able to accomplish a typical broadcaster to receiver application, but I am not sure what the best way to go about adding multiple broadcasters is.
I can currently see two real choices. Assign each member in the group a number (or use the ID's) and then create an additional receiving stream for each member that connects, or create 5 differen't group specifiers basically making 5 different instances of the application with one broadcaster and 4 receivers.
If anyone can help me think of a better way, that would be great.
Also, is there a way to find out the total number of users in a group or to access their ID's?
Thanks.

Take a look at the 3 packages that start with "java.util.concurrent", and the methods of java.util.Collections that start "synchronized. . ." and you can probably find something that will work for your situation.

Disabling Voice chat in game Center games

I would like to disable the voice chat feature entirely out of Game Center based games. My kids occasionally play the iPad and I've heard them conversing with random people over games.

Just for the record and for the other concerned parents, I've taken the iPad away for now until I can get this figured out. Thank you all for your forthcoming help!

Sound, voice chat, yahoo messenger and VPC 6

Okay perhaps off topic..perhaps not......how do I get sound to work in Yahoo messenger v 7 w/ voice chat via VPC 6 on an AL 15 Powerbook???
And does the AL 15 have a built in Microphone??

Does the microphone work while running VPC?
I don't know, but I think you can easily check. While you're running VPC, go into System Preferences > Sound > Input. (You can access System Preferences from the Apple menu in the upper left-hand corner of your screen. I'm assuming that you can do this while running VPC. If I'm wrong on this, please stop reading this worthless post. ;-))
Look at the meter that reads "input level," just above the slider that reads "input volume." If there's any significant ambient noise where you are, or if you speak at a decent volume out loud (it doesn't even have to be near the mic, which is located beneath the left speak grille), you should see the "input level" fluctuate if the mic's working properly. (The default setting for the "input volume" is midway on the slider. If it's all the way to the left, the mic will not pick up any sounds.)

HP Pavilion dv7-6b78us Sound Problem (sound routes to built-in speakers during voice chat)

I'm having an issue with my laptop. When I play using Steam with headphones plugged in, and I attempt to start a voice call, the sound routes to the built-in speakers and I cannot switch it back to just headphones.
I tired unplugging and replugging the headphones, that didn't work,and turning down the speaker sound made the game sound not go through the headphones. What could be wrong? Restarting fixes the issue, but it happens everytime I attempt to voice chat...

This used to happen to me when I 1st purchased my laptop. Heres a solution that worked for me.
RIght click on your audio icon next to the clock, then left click the "Playback Devices" option.
On this window, look for the tab named "Communications" at the top. Heres a screenshot: http://puu.sh/4OtOO.png
When on this tab, click on "Do Nothing" this will prevent windows from switching your headphone to the speakers everytime you get a new notification.
Cheers.

Trouble With Voice-Chat In Ga

Hi I have an Audigy 2 Platinum and am currently having problems when using voice chat when playing games. Whenever I speak I hear myself being repeated through my speakers a second or so after, so that I can hear what I am currently saying along with what I've just said at the same time. I am using a Labtec PC mic connected to the Mic In 2/Line In 2 connection on the break-out box at the front of my computer. I thought it might just be a latency issue causing a delay from when I say something to when I actually hear it but I'm not sure how to confirm this or how to change the settings in the mixer. Could anyone please help me with this. Thanks very much!

Since Yahoo Messenger is not an Apple product you should look to Yahoo support for answers:
http://help.yahoo.com/l/us/yahoo/messenger/mac/index.html
Of since you're friends are the ones who receive the error message, perhaps they should upgrade their messenger.

Voice chat in ut2k4 won't work [not solved yet]

I have already tried the following resources:
http://www.linux-gamers.net/modules/wfs … ticleid=34
http://www.thehaus.net/Tips/UT/ut2004icculusfaq.shtml
my ~/.openalrc:
Contains user settings for OpenAL
; Which backend? Tried in order of appearance.
;(define devices '(native alsa sdl esd arts null))
(define devices '(alsa sdl esd))
; Four speaker surround with ALSA.
(define speaker-num 2)
;(define alsa-out-device "surround40:0,0")
(define alsa-out-device "hw:0,0")
; For alsa-in support. Mainly for using voice chat.
(define alsa-in-device "hw:1,0")
;hw:1,0 because i use my second sound card to record on many programs (ie audacity) bc emu10k1 only records the sound out not mic.
; Some drivers do not support select.
;(define native-use-select ;t)
symptoms:
sound works great, clear and not laggy at all. i have all the voice chat keys mapped and all the good voice chat options enabled. everytime i press a key that chats, either teamchat or public-chat the sound gets sort quiet (like it's supposed to, to avoid feedback). the problem is nobody hears me at all, not even a "turn up you volume dude!" or "what was that?!"

this is what i see on "alsamixer -V capture" i turned on the mic capture and encreased it's volume. still the same syptoms persist in any recording app set to use the audigy gamer. no matter where i plug in the mic the app only records the outgoing sounds from the sound servers and apps but never the mic.
btw: on all distros my kmix has never had anything in the input tab, (no record sources) when you click mixer in the tray of kde.
