OpenALException: Invalid Device

Troubleshooting sound
1

Hello Guys,
Anyone knows what this exception might be? I understand that it is an “invalid device” but what is the common issue in such cases? need to update the card driver?
Does any of the capabilities list below indicate what the problem might be?

Thanks!

If the application doesn’t need audio/sound, you can simply disable it using AppSettings.setAudioRenderer(null). If it needs sound, then OpenAL needs to be debugged.

Thanks a lot! it’s not on my computer so I cannot debug it but I will add the option to disable the audio renderer in next version and hope it will solve such cases.
