I’m not sure if this a problem at the Pencil side but when adding audio tracks to Pencil2d I can’t hear them when playing the movie in Pencil. When exporting to mp4 sounds is there as expected. I guess is something misunderstanding between Pencil and GNOME audio system.
Using Fedora 26 with GNOME 3.24.2.
I can reproduce that with 0.6.1.1 on Arch Linux. Seems to be another shortcoming of linuxdeployqt, see https://github.com/probonopd/linuxdeployqt/issues/96 and https://github.com/probonopd/linuxdeployqt/issues/123. Apparently it’s possible to work around that problem somehow, but I haven’t looked super closely at those issues yet. I’d consider this a relatively major problem for us, though, since sound is one of our core features, so we should look into getting this working for us. I think I’ll open an issue in our bug tracker for this.
