--- Comment #14 from Alex axfelix@gmail.com --- Yup, 90% of my audio comes over USB A2DP Bluetooth via Pulse -- /that's/ why I know actually problematic latency when I hear it :)
I get my wine builds from the ubuntu-wine PPA, per https://www.winehq.org/download/ubuntu, on the assumption that this represents the closest-to-intended "stock" environment. Would be happy to switch to some more "official" build if it's as easy to maintain.
