Hi folks, I’m also having problems getting passthrough to work. It worked under Kodi 16.
In the log file I see the message “ERROR: PulseAudio: Waited for the stream but it failed”
Playing standard scene MKVs with h.264 video and ac3 5.1 audio. I’m using PlexKodiConnect to play media from a local Plex server. I have Passthrough and AC3 enabled. Video sync is disabled. Plays in PCM 2-channel mode fine.
Computer (ASUS Chromebox with Matt Devo’s coreboot) connected to TV with HDMI, TV connected to Receiver with S/PDIF

Kodi version: 17.1 Git:20170320-nogitfound
OS: up-to-date xubuntu 16.04.2 LTS (GNU/Linux 4.4.0-71-generic x86_64)
I started with a clean profile with just PlexKodiConnect and YouTube added.
