Armory: Cannot open audio device default when running

[DrLuke]

When I try to run the default startup scene with the Krom runtime, I get the following error in the console:

ALSA lib pcm_dmix.c:1108:(snd_pcm_dmix_open) unable to open slave cannot open audio device default (Device or resource busy)

I am running on Arch Linux with pulseaudio. Please let me know if you need any more information.

Also, is there any way to disable the sound system so I can continue working?

[DrLuke]

Sound can be disabled in Armory Project -> Modules, but it still tries to open an audio device. Shouldn't it not do that when audio is disabled?

Are you a member of the audio group? I think we had that (or something quite similar) and it turned out one of the problems was a permission issue with the user.

[DrLuke]

I've added myself to the audio group but still get the same error. Good idea though!

[sh-dave]

Just to make sure, you rebooted / relogged as well?

Can you play sounds in the commandline with aplay?

• e.g. aplay /usr/share/sounds/alsa/Rear_Right.wav

Aha! Installing alsaplayer gives me the following error(s):

ALSA lib pcm_dmix.c:1108:(snd_pcm_dmix_open) unable to open slave snd_pcm_open: Device or resource busy (default) Failed to initialize plugin! /usr/lib/alsaplayer/output/libalsa_out.so failed to load connect(2) call to /dev/shm/jack-1000/default/jack_0 failed (err=No such file or directory) attempt to connect to server failed jack: server not running? /usr/lib/alsaplayer/output/libjack_out.so failed to load error opening /dev/dsp Failed to initialize plugin! /usr/lib/alsaplayer/output/liboss_out.so failed to load NOTE: THIS IS THE NULL PLUGIN.

Reinstalling the package pulseaudio-alsa fixed the issue, some auto-generated configuration probably was wrong for whatever reason. Thank you!
