At Mozilla, we're in the process of adding support for WebRTC (http://webrtc.org/), which is being standardized by the IETF (their part is 'rtcweb'), and the W3C. This adds real-time audio and video (and data) communication to browsers, peer-to-peer over encrypted channels. We have a sound library that can load either Pulse or Alsa. However, for Alsa, it wants to look at snd_device_name_hint() and also _get_hint() and _free_hint(). It lazy-binds to libasound, so it will dlopen() it and then dlsym() all the symbols it uses; if any fail it unloads the lib and says it's not there. It uses the hint functions to build a device list, for example for presenting to the user. I have two problems: 1) Firefox is build on machines configured with I believe Centos5, and I'm told the machines run Alsa 1.0.12, while the hints() functions were added in 1.0.14 (released June 2007). Right now I can't build release or 'try' builds on the build servers because of this. 2) We'd like to run on older machines if possible, and official release builds are made on those servers. On older machines, _hint() aren't available, so even if I make them optional to dlsym-loading, I would need some other method to get the information I assume using older, now-deprecated-or-gone interfaces. Any suggestions? Tips? Should I ask in -devel? See http://code.google.com/p/webrtc/source/browse/trunk/src/modules/audio_device/main/source/linux/audio_device_alsa_linux.cc?r=347#2348 for how they're used currently.
