[Bug 1315212]
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
alsa_output.pci-0000_06_00.0.analog-stereo with sample spec s16le 2ch 48000Hz and channel map front-left,front-right
