Why Renoise isn’t able to play when other applications are playing (or after other application have used the audio resource)?
As far as we know, in many desktop manager an audio manager is provided (ex. aRts on KDE or ESD in GNOME). The audio manager often locks the audio resource for it’s own use (this may happen while and after an application used it for playback). So, to solve the problem try disabling the audio manager and set all your audio application to use ALSA directly: ALSA is capable of sharing the audio resource out-of-the-box. Renoise gives out of memory errors when loading particular songs / samples while i have enough memory Be sure that you have not restricted your virtual memory settings on any global level in Linux or that no virtual memory restrictions are set. You can check out your virtual memory settings by entering ulimit -a in a console.
