As you may have read Mozilla has discontinued ALSA support with Firefox 52. It is no longer included by default. Pulseaudio is the only supported sound server under Linux now. The SeaMonkey team has decided to enable it for ESR 2.49 which corresponds to ESR 52.

As a test if it still works ok it has been enabled in aurora (2.51) builds for now. It would be great if someone can test if this still works as expected. If pulseaudio is available it will be used. ALSA is the fallback. It is a stopgap solution and ALSA will not be enabled for SeaMonkey beyond 2.51 (already broken in tests sourcecode by Mozilla devs in 2.52 a week ago).

The latest build is here: ... mm-aurora/

2.51a2 has known problems e.g. formhistory in Data Manager and other places is broken. Lightweight theme support and other things are also broken but for general browsing it should be ok. Please backup your profile before testing.

Thanks for testing.

Let's move this to SM Builds given that it's about testing a feature in pre-release versions.

Noticed this in the changelog for Firefox 52.0.2, Ubuntu.
Thought it might be of some interest even though it's not SeaMonkey.
* Fix LP: #1671273 - Build with --enable-alsa for now to re-enable the
unmaintained ALSA backend. Note that problems with the ALSA backend will
not block future updates and Ubuntu flavors that ship without Pulseaudio
need to participate in maintaining this code

Yes, OpenSUSE has it enabled on their regular Firefox 52 builds as well, so it works and shouldn't be a problem for the 2.49.x releases from the 52 ESR branch.
