Firefox Goes PulseAudio Only, Leaves ALSA Users With No Sound

An anonymous reader shares a report: If you’re a Linux user who upgraded to Firefox 52 only to find that the browser no longer plays sound, you’re not alone. Firefox 52 saw release last week and it makes PulseAudio a hard dependency — meaning ALSA only desktops are no longer supported. Ubuntu uses PulseAudio by default (as most modern Linux distributions do) so the switch won’t affect most — but some Linux users and distros do prefer, for various reasons, to use ALSA, which is part of the Linux kernel. Lubuntu 16.04 LTS is one of the distros that use ALSA by default. Lubuntu users who upgraded to Firefox 52 through the regular update channel were, without warning, left with a web browser that plays no sound. Lubuntu 16.10 users are not affected as the distro switched to PulseAudio.

Faster 3D rendering with WebGL 2.0

WebGL 2.0 Transform Feedback demo (live link, Github repository)

WebGL 1.0 first launched in Chrome 6 years ago and gave web developers the ability to create immersive plugin-free graphics experiences, from remixing World Cup plays in real-time to visualizing a rock climbing route in a news article. WebGL 2.0 makes it even easier to build 3D web applications, with faster real-time rendering, new types of textures and shaders, and reduced video memory consumption.  Techniques including deferred shading, tone mapping, volumetric effects, and particle effects can now be efficiently implemented. The new APIs also bring WebGL up to feature parity with OpenGL ES 3.0, a graphics platform commonly used in mobile games.

In addition to new rendering capabilities, WebGL 2.0 also introduces a substantially expanded conformance test suite with over 340,000 test cases to help ensure that different web browsers offer compatible graphics platforms. Chrome passes 100% of these test cases across multiple
