Although au88x0 support hardware mixing, there is only one pair of
AC97 input CODECIN(0), CODECIN(1) for capturing stereo sound using hw:0,0

# more /proc/asound/au8830/pcm0c/info
card: 0
device: 0
subdevice: 0
stream: CAPTURE
id: AU88x0 ADB
name: adb
subname: subdevice #0

subdevices_count: 32
subdevices_avail: 32


It seem that multiple instances of arecord can be run at the same time.
1) Is this a bug ?

2) Do we need to define snd_vortex_capture_hw_adb to prevent multiple
programs perform recording while allowing multiple playback for ALSA and
OSS emulation ?
