@Jens -- whatever DNS server you are using while connected to VPN probably doesn't quickly return an answer for a AAAA query for "localhost," while your non-VPN DNS does. alsa-utils 1.0.17-0ubuntu3 should avoid it in all cases. Also, see below.
@kungmidas -- when I change my DNS to some bogus address, I see this delay. When I use good DNS servers, the delay is gone. alsa-utils 1.0.17-0ubuntu3 should avoid it in all cases. Also, see below.

@all, please see https:/ /bugs.launchpad .net/ubuntu/ +source/ network- manager/ +bug/274995/ comments/ 273 -- if you were seeing a delay -- even if it is fixed now, you probably also have or had that separate network configuration bug 301430 that allows DNS queries for localhost -- however generated -- to escape your local machine and network.
