Second Life - Linux Voice Support README -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= WHAT IS IT? -=-=-=-=-=- Linux Voice Support is a feature in testing which allows users of the Linux Second Life client to participate in voice-chat with other residents and groups inside Second Life, with an appropriate headset/microphone. Linux Voice Support is currently EXPERIMENTAL and is known to still have some compatibility issues. SINGULARITY MULTI-VOICE -=-=-=-=-=-=-=-=-=-=-=- Singularity multi-voice is an experimental feature that allows you to run multiple SLVoice daemons at the same time, in order to do this, the debug setting VoiceMultiInstance must be TRUE, this allows multiple instances of the viewer to run concurrently and each connect to voice. REQUIREMENTS -=-=-=-=-=-= * A headset/microphone supported by your chosen version of Linux * The ALSA sound system (you probably already have this - i.e. the alsa-base and alsa-utils packages on Ubuntu) Success with Linux Voice support has been reported on the following systems: * Ubuntu 6.06 (Dapper) with Intel ICH5/CMI9761A+ audio chipset * Ubuntu 6.06 (Dapper) with SigmaTel STAC2997 audio chipset * Ubuntu 6.06 (Dapper) with Creative EMU10K1 audio chipset * Ubuntu 7.04 (Feisty) with USB Plantronics headset * Ubuntu 7.04 (Feisty) with Intel HDA audio chipset * Fedora Core 6 with (unknown) audio chipset * Ubuntu 8.04 (Hardy) with (unknown) audio chipset TESTING YOUR SETTINGS -=-=-=-=-=-=-=-=-=-=- * The Second Life region 'Voice Echo Canyon' is a great place for testing your hardware settings and quality - it will 'echo' your voice back to you when you speak. KNOWN PROBLEMS -=-=-=-=-=-=-= * The 'Input Level' meter in the Voice Chat Device Settings dialog does not respond to audio input. TROUBLESHOOTING -=-=-=-=-=-=-=- PROBLEM 1: I don't see a white dot over the head of my avatar or other Voice-using avatars. SOLUTION: a. Ensure that 'Enable voice chat' is enabled in the 'Voice Chat' section of the Preferences window, and that you are in a voice-enabled area (you will see a blue headphone icon in the SL menu-bar). b. If the above does not help, exit Second Life and ensure that any remaining 'SLVoice' processes (as reported by 'ps', 'top' or similar) are killed before restarting. PROBLEM 2: I have a white dot over my head but I never see (or hear!) anyone except myself listed in the Active Speakers dialog when I'm sure that other residents nearby are active Voice users. SOLUTION: This is an incompatibility between the Voice support and your system's audio (ALSA) driver version/configuration. a. Back-up and remove your ~/.asoundrc file, re-test. b. Check for updates to your kernel, kernel modules and ALSA-related packages using your Linux distribution's package-manager - install these, reboot and re-test. c. Update to the latest version of ALSA manually. For a guide, see the 'Update to the Latest Version of ALSA' section of this page: or the official documentation on the ALSA site: - reboot and re-test. PROBLEM 3: I can hear other people, but they cannot hear me. SOLUTION: a. Ensure that you have the 'Talk' button (at the bottom of the Second Life window)activated while you are trying to speak. b. Ensure that your microphone jack is inserted into the correct socket of your sound card, where appropriate. c. Use your system mixer-setting program (such as the PulseAudio 'volume control' applet or the ALSA 'alsamixer' program) to ensure that microphone input is set as the active input source and is not muted. d. Verify that audio input works in other applications, i.e. Audacity PROBLEM 4: Other people just hear bursts of loud noise when I speak. SOLUTION: a. Use your system mixer-setting program or the 'alsamixer' program to ensure that microphone Gain/Boost is not set too high.
