I can't really comment on the bug that this has been hijacked into, which there's apparently been progress on, but if anything the "no sound" behavior is actually *worse* in 6.1.18 than 6.1.16 from a user perspective, as toggling the Audio Out enable state (which used to successfully restart the audio close to 100% of the time) has yet to work for me even once in .18.(COULD just be bad luck, but the chances of that are getting very thin already).
