Not to answer my own post, but in fact I missed that it updated
libasound2 as well. That is what broke my playback. It only happened
on a video that the card was downsampling 5.1 to stereo.. Caused it
to play half speed for some reason..
In case anyone else runs into this.. Dunno if it matters, but it is a
nvidia ion chip, using hdmi out for audio... It affected other
computers as well though (but I am not 100% sure how it streams to
frontends), so it may have been this hardware entirely, or bad
libasound alltogether..
