11 ALSA provides a powerful OSS emulation on the kernel.

35 On ALSA, you can symlink /dev/sndstat to this proc file.

69 Unlike the real OSS, ALSA cannot use the device files more than the
74 PCM device (``hw:0,0`` in ALSA) is mapped to /dev/dsp and the secondary
122 As default, ALSA emulates the OSS PCM with so-called plugin layer,
186 As default, ALSA behaves as original OSS drivers, i.e. does not block
224 Since ALSA has completely different mixer interface, the emulation of
225 OSS mixer is relatively complicated.  ALSA builds up a mixer element
226 from several different ALSA (mixer) controls based on the name
234 As default, ALSA uses the following control for OSS volumes:
237 OSS volume		ALSA control		Index
266 The second column is the base-string of the corresponding ALSA
282 the base-string of the corresponding ALSA control, and the third the
