--- Comment #64 from Raymond <superquad.vortex2 at gmail.com> ---

if you cannot find stereo 48000Hz wav file

aplay -D plughw:CARD=CA0106 -v --buffer-size=1024 any.wav

try to find minimum buffer size 1024,512, 256,128,64,... without underrun


1024 frames = 21.33 ms x 48000Hz
4096 = 85.33 ms x 48000Hz

if request tlength 85.33ms is buffer time and 21.33ms is period time

not sure why pulseaudio received latency is 26ms
