comparing wodOpen() in winealsa.drv and winecoreaudio.drv

winecoreaudio

DWORD wodOpen(WORD wDevID, WINE_WAVEOUT_INSTANCE** pInstance, LPWAVEOPENDESC
lpDesc, DWORD dwFlags)

winealsa

DWORD wodOpen(WORD wDevID, LPWAVEOPENDESC lpDesc, DWORD dwFlags)

To support multiple waveoutopen, winealsa need to pass additional parameter
(i.e. pointer to the voice ) similar to WINE_WAVEOUT_INSTANCE in
winecoreaudio.drv
