--- Comment #2 from Austin English austinenglish@gmail.com 2012-11-19 14:27:14 CST --- A) Please retest in 1.5.17. B)
ALSA lib conf.c:3314:(snd_config_hooks_call) Cannot open shared library libasound_module_conf_pulse.so ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM default
you may be missing 32-bit alsa/pulse libs
C) Native dotnet may work better than mono, if those two suggestions don't help.
