Hi, pulseaudio ALSA emulation doesn't work correctly me still believe it's cause of the resampler. If you want to see an application crash because of pulseaudio virtual device, please visit ags.sf.net At least want to complain about not able to shut down pulseaudio to uninstall is the only option for me. Generally I like pulseaudio. My project was initiated in 2002 and many efforts were done in testing for reliability. You may experience thread tree hanging up at start time so you have to restart Advanced Gtk+ Sequencer. Contributions are appreciated. What buffer time do you recommend? Me preferring 943 frames per buffer. thank you in advance Jo?l
