H A Doss-emulation.rst2 Notes on Kernel OSS-Emulation
11 ALSA provides a powerful OSS emulation on the kernel.
12 The OSS emulation for PCM, mixer and sequencer devices is implemented
13 as add-on kernel modules, snd-pcm-oss, snd-mixer-oss and snd-seq-oss.
14 When you need to access the OSS PCM, mixer or sequencer devices, the
22 Only necessary step for auto-loading of OSS modules is to define the
