1Second Life - Linux Voice Support README 2-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= 3 4WHAT IS IT? 5-=-=-=-=-=- 6 7Linux Voice Support is a feature in testing which allows users of the Linux 8Second Life client to participate in voice-chat with other residents and 9groups inside Second Life, with an appropriate headset/microphone. 10 11REQUIREMENTS 12-=-=-=-=-=-= 13 14* A headset/microphone supported by your chosen version of Linux 15* At this time, the PulseAudio audio system is recommended; this software 16 is already part of most modern (2009+) Linux desktop systems. Alternatively, 17 the ALSA audio system may be used on systems installed from around 18 2007 onwards (again this is likely already installed on your system). 19 20TESTING YOUR SETTINGS 21-=-=-=-=-=-=-=-=-=-=- 22 23* The Second Life region 'Voice Echo Canyon' is a great place for testing 24your hardware settings and quality - it will 'echo' your voice back to you 25when you speak. 26 27KNOWN PROBLEMS 28-=-=-=-=-=-=-= 29 30* Compatibility with old ALSA-based audio systems (such as Ubuntu Dapper 31 from 2006) is poor. 32 33TROUBLESHOOTING 34-=-=-=-=-=-=-=- 35 36PROBLEM 1: I don't see a white dot over the head of my avatar or other 37 Voice-using avatars. 38SOLUTION: 39a. Ensure that 'Enable voice' is enabled in the 'Sound' section of the 40 Preferences window, and that you are in a voice-enabled area. 41b. If the above does not help, exit Second Life and ensure that any 42 remaining 'SLVoice' processes (as reported by 'ps', 'top' or similar) 43 are killed before restarting. 44 45PROBLEM 2: I have a white dot over my head but I never see (or hear!) anyone 46 except myself listed in the Active Speakers dialog when I'm sure that other 47 residents nearby are active Voice users. 48SOLUTION: This is an incompatibility between the Voice support and your 49 system's audio (ALSA) driver version/configuration. 50a. Back-up and remove your ~/.asoundrc file, re-test. 51b. Check for updates to your kernel, kernel modules and ALSA-related 52 packages using your Linux distribution's package-manager - install these, 53 reboot and re-test. 54c. Update to the latest version of ALSA manually. For a guide, see the 55 'Update to the Latest Version of ALSA' section of this page: 56 <https://help.ubuntu.com/community/HdaIntelSoundHowto> or the official 57 documentation on the ALSA site: <http://www.alsa-project.org/> - reboot 58 and re-test. 59 60PROBLEM 3: I can hear other people, but they cannot hear me. 61SOLUTION: 62a. Ensure that you have the 'Speak' button (at the bottom of the Second Life 63 window) activated while you are trying to speak. 64b. Ensure that your microphone jack is inserted into the correct socket of your 65 sound card, where appropriate. 66c. Use your system mixer-setting program (such as the PulseAudio 'volume 67 control' applet or the ALSA 'alsamixer' program) to ensure that microphone 68 input is set as the active input source and is not muted. 69d. Verify that audio input works in other applications, i.e. Audacity 70 71PROBLEM 4: Other people just hear bursts of loud noise when I speak. 72SOLUTION: 73a. Use your system mixer-setting program or the 'alsamixer' program to ensure 74 that microphone Gain/Boost is not set too high. 75 76FURTHER PROBLEMS? 77-=-=-=-=-=-=-=-=- 78 79Please report further issues to the public Second Life issue-tracker 80at <http://jira.secondlife.com/> (please note, however, that this is not 81a support forum).
