installed orca without problems. However, running orca gives following error: orca -s Traceback (most recent call last): File "/usr/lib/python-exec/python3.5/orca", line 44, in <module> from orca import orca File "/usr/lib/python3.5/site-packages/orca/orca.py", line 80, in <module> from . import sound File "/usr/lib/python3.5/site-packages/orca/sound.py", line 163, in <module> _player = Player() File "/usr/lib/python3.5/site-packages/orca/sound.py", line 55, in_init__ self.init() File "/usr/lib/python3.5/site-packages/orca/sound.py", line 123, in init self._pipeline.add(self._sink) File "/usr/lib/python3.5/site-packages/gi/overrides/Gst.py", line 62, in add if not Gst.Bin.add(self, arg): TypeError: Argument 1 does not allow None as a value changing profile from default/linux/x86/17.0 to default/linux/x86/17.0/desktop/gnome/systemd did not help. emerge -a gst-plugins-good gst-plugins-pulse solved this problem. background: intention is to have an accessible setup to run a few gui apps (e.g., firefox, evince) while mainly using emacspeak as an environment --> purpose is to avoid as much as posible unnecessary gnome stuff. This is probably the reason why these packages were not installed and would ideally be pulled in by emerging orca.
Need gst-plugins-good for autoaudiosink, maybe more. This needs grepping the sources for the explicitly created elements and possibly maybe also gst-plugins-meta, though I'd expect more the explicit kind than needing support to play any kind of media, in case of orca.
