I don't think so. On soundcards able to play multiple streams at once, it's possible to open /dev/dsp multiple times even with OSS. So if the emulation is done correctly, and it operates over dmix, it should be possible to open /dev/dsp by more applications. Actually I've read in some dmix how-to this is supposed to work. But I'm also a little puzzled with the magic of /etc/asound.conf and with what it's supposed to contain to make dmix and oss emulation work (and the last step, make them work together). I would recommend asking on alsa-users at alsa-project.org. With regards, Hynek Hanke
