Created attachment 535182 [details] emerge --info vlc vlc doesn't output any sound when playing a video with an opus audio track, although I compiled it with opus support (see emerge --info). My test video is one downloaded from youtube with youtube-dl, resulting in an h264 video and opus audio track. mpv can play that video without any problems: $ mpv Silverstein\ -\ Ghost\ \(Official\ Music\ Video\)-SqDR4TW2vfs.mkv Playing: Silverstein - Ghost (Official Music Video)-SqDR4TW2vfs.mkv (+) Video --vid=1 (*) (h264 3840x2160 23.976fps) (+) Audio --aid=1 --alang=eng (*) (opus 2ch 48000Hz) AO: [pulse] 48000Hz stereo 2ch float VO: [opengl] 3840x2160 yuv420p Below the console output of VLC. The filter errors also appear with videos where the sound works fine.

The Opus sound in a WebM (a Matroska subset) container video plays for me if the matroska USE flag is set, and not otherwise.
I have this same problem when USE=matroska is not enabled.
Are you still hitting this with 3.0.18?
