Using 64bit Arch Linux, installed OpenRA via pacman.

Try installing the OpenAL library. If you already have and this solves nothing start the game without sound as a workaround by writing this into $HOME/openra/settings.yaml

Code: Select all

Sound&#58;
	Engine&#58; Null

I'm using the ALSA > JACK PCM plugin in .asoundrc, see: http://jackaudio.org/routing_alsa

If I disable that then OpenRA starts up as normal.

The errors I posted earlier are with the ALSA JACK plugin and JACK is running. I don't know if it's a problem with openal or with openra.

Thanks.

Does sound work without jack through default device? If so you should probably post bug on http://bugs.open-ra.org.
