Please note: Viewers play a minor part in voice functionality. The bulk of voice support is given by the external application called SLVoice, which is made by the SL voice provider, Vivox. Voice failures are almost always due to one of the following reasons:
Please go to Voice Echo Canyon when trying to get voice to work. If voice is working correctly for you, anything you say there will be echoed back to you. Once there, relog to last location.
Due to the many different versions of each operating system (Windows, linux distros, Mac OSx's), it is very difficult to give specifics for each one. Nonetheless, make sure that your operating system is correctly configured for voice: that voice is going to your headset (or speakers, as you prefer), and that your mic is enabled and configured.
If voice still does not work, then continue working through this page.
If using Firestorm 4.5.1 and 4.6.1 on Windows, please see here.
If you find that voice cuts in and out, particularly right after a TP, and at the same time, you notice that things are not rezzing in for you very well (avatars, objects, etc), then the likely cause is that your router is being “overwhelmed” with texture transfers. So try the following:
If that does not help, then proceed with the section below.
Chances are good that the problem lies with the SL servers or the voice provider, Vivox. Still, there are things you can try:
Don't do this section if using Firestorm 18.104.22.168833.
Some have issues with voice on Firestorm 4.5.1 or 4.6.1 - specifically, “stuttering”. The only work-around currently is to swap out the voice files.
To this end, download this file; save it to your hard drive. Make sure you do not have Firestorm running. Then extract the files to your Firestorm install folder. (For Firestorm 32-bit viewer, this is typically located at C:\Program Files\Firestorm on 32 bit Windows, and C:\Program Files (x86)\Firestorm on Windows 64-bit. For Firestorm 64-bit Viewer, this is typically located at C:\Program Files\Firestorm.) When prompted, allow the replacement of existing files.
Try disabling compatibility mode, if enabled:
On Windows 7, if you find yourself being able to talk but not hear what others say, then a possible solution is to use the sound drivers from Vista. (This needs further confirmation.)
Check that slvoice.exe is not muted in the speaker/headphones icon (located in the notification area) → mixer.
Every linux distro is different; and each distro may have more than one window manager to further complicate things. So tips can't be “absolute”; you will need to experiment and see what works for you. The following have been suggested by some as effective. But first….
In the Firestorm install directory, there's a text file (originally from LL) with tips on getting voice to work in linux. If you haven't read that, then you can try to see if it helps.
Below are results for selected linux distros, based on input from Phoenix and Firestorm users. This will be updated as more information becomes available.
sudo apt-get install gstreamer0.10-pulseaudio:i386 libidn11:i386 libuuid1:i386 libstdc++6:i386
If you are unable to connect to voice and you are also having problems with teleporting and/or loading your friends list, perhaps along with other things, then see the “Mac-specific” section of this page for instructions and more explanation.
Some Mountain Lion users experience a problem with voice output, while input works fine (that is, you can hear but you can't speak). To fix this, open the voice preferences for your viewer (Preferences → Sound & Media -> Voice Settings in Firestorm). Click the device settings button and select “built-in microph” as the audio input device and click OK. (OK is important, Apply doesn't work.) Reopen Preferences and go back to the device settings button to ensure you're getting sound in on the mic.
