I'm running Void Linux, and seem to remember sound with recharged when I first got it, so maybe a recent change?
Just FYI ... I'm using both classic and recharged on a Xubuntu 14.04.4 64-bit Linux machine and the sound works well for me. No problems whatsoever... I'm using pulseaudio backend.
No, nothing has changed, except that the new version is built with a new version of Unity (That is used for development).
The Unity team will hopefully fix the Linux build issues in some coming update.
Glad to hear it works fine for you Misklach.
