Besides glade and GTK Warnings this was the only output:

ALSA lib conf.c:3949:(snd_config_expand) Unknown parameters 0
ALSA lib pcm.c:2145:(snd_pcm_open_noupdate) Unknown PCM default:0
ALSA lib conf.c:3949:(snd_config_expand) Unknown parameters 0
ALSA lib pcm.c:2145:(snd_pcm_open_noupdate) Unknown PCM default:0
