alsa-lib 1.1.2 breaks Firefox html5 sound.

Hello there,

running a jack-only system which used to work 100% fine. Nevertheless, since upgrading Firefox to 48.0-2 and especially alsa-lib to 1.1.2-1 breaks sound on all videos (vimeo, youtube).

When loading such video, the playback doesn't progress, no video and no sound.

Downgrading alsa-lib to the previous 1.1.1-1 makes everything work again, allthough there is a slight digital distortion after a while.

Anyone got a clue what could have lead to this?

Many thanks in advance,

m.
