The primary speed advantage, hardware mixing, a slower kludgy implementation use due to the fact that looping sound doesn't appear to be supported; although full duplex support should be easier to provide than with OSS. The major drawback of ALSA is that its mmap interface is not compatible with what is required for DirectSound unless undocumented interfaces are used. All in all it appears that using ALSA would provide some speed advantages for newer cards, but to be done properly would require a rewrite of the winealsa driver. Thus we would suggest that, for the time being, people continue to use the OSS emulation layer of ALSA with "MMap" = "Y" enabled in their config file to get the best performance if it's supported on their sound card." Apart from mmap which I guess is architectural and quite difficult to change, what about their comments on looping sound - useful?
