* Disable ALSA backend for Firefox 55 because it makes the build failure.
This will remain disabled until somebody steps up to maintain it
So ALSA support got temporary disabled because the current state seems to be not fully compatible with Firefox 55. Hopefully this can be fxed soon but since upstream (Mozilla) does not intend to reconsider supporting ALSA again I wonder if this will get more and more tricky to maintain for downstream (Ubuntu) in the future and if at some point support for ALSA will fully stop.
I just read this on the changelog:
