ALSA NOTE: When using the alsa driver, the "default" translates to "hw", >not "default", before being sent to the ALSA API. This is necessary because >ALSA's "default" audio device has very poor buffering control capabilities. If >you really want to use ALSA's "default" device, use "sexyal-literal-default".
The problem is in src/sexyal/drivers/alsa.c:312. A call to "snd_pcm_hw_params_set_period_size()" that works with "hw" device fails with "default" device. Using a Sound Blaster Live! (emu10k1) the default device works correctly. Using "-sounddevice default" you end with

and using "-sounddevice sexyal-literal-default" with
