The problem in your waveout.c 

 waveout_count = ALSA_WodNumDevs;

ALSA_WodNumDevs is the total numbers of playback device 0 of alsa sound cards

So you need at least two sound cards so that waveout_count > 1 for your
waveout.c to allow multiple open

if AutoScanDevices="Y", this will be the number of all playback devices (
including spdif, hdmi, ...) of alsa sound cards 



for hardware mixing sound cards, the therotical maximum number is the value
returned by snd_pcm_info_get_subdevice_count();

**** List of PLAYBACK Hardware Devices ****
card 0: Live [SBLive! Platinum [CT4760P]], device 0: emu10k1 [ADC
Capture/Standard PCM Playback]
  Subdevices: 32/32

however the practical number can be reduced when the other application is using
the WaveTable Synth 



you can try waveout.c in bug#22880  comment#4

which limit the maximum number of waveoutopen to 16

Allow multiple waveoutopen to the same device is depend on the result of
snd_pcm_open

Not sure wine can open "plug:dmix" or "pulse" device how many times ?
