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

Title:
  [CA0106 - CA0106, playback] Playback problem - Surround dies, no valid
  output

Status in ALSA driver:
  Confirmed
Status in alsa-driver package in Ubuntu:
  Incomplete

Bug description:
  This is tested against a Creative Labs Sounblaster live! (sb0410) card
  and a SoundBlaster Audigy se (sb0570). Both of them behave strangely,
  output coming through some, but not all speakers, etc. This was
  working in 13.10 under the sb0410. the ca0106 driver is the same for
  both cards.
