if you have two alsa sound cards (onboard HDA and another PCI sound card/USB
audio ), you should notice that you have two waveout devices with name
"default" and two wavein devices with name "default" but two mixer devices with
"hw:0" and "hw:1" 

WINEDEBUG=+mixer winecfg

wine use alsa "default" device instead of hw:0,0 or hw:1,0 / plughw:0,0 ,
plughw:1,0 after alsa drop the support of default:0 , default:1 (i.e. wine had
actually drop the multiple sound cards support after this change )


wine use snd_card_get_index() to find all alsa cards and use snd_ctl_open() to
use the control interface ( need patch to skip those rawmidi cards
http://bugs.winehq.org/show_bug.cgi?id=21361#c2 ) and call snd_mixer_open() to
use the simple mixer interface to find all the volume controls and switches of
the sound card and add "hw:n" to mixer devices list

if you are using Puleaudio , (winealsa.drv with alsa-pulse plugin )

pcm.default has been configured to use pcm.pulse
ctl.default has been configured to use ctl.pulse

pasuspender is not easy to temporarily suspend PulseAudio when 
1) your distribution turn of auto spawn feature of PA server , 
2) unless you disable all system event sound  after libcanberra ( system event
sound ) use pulseaudio
