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
48 PCM:
73 As seen above, PCM and MIDI may have two devices. Usually, the first
74 PCM device (``hw:0,0`` in ALSA) is mapped to /dev/dsp and the secondary
79 snd-pcm-oss and snd-rawmidi. In the case of PCM, the following
80 options are available for snd-pcm-oss:
83 PCM device number assigned to /dev/dspX
86 PCM device number assigned to /dev/adspX
89 For example, to map the third PCM device (``hw:0,2``) to /dev/adsp0,

122 As default, ALSA emulates the OSS PCM with so-called plugin layer,
128 In such a case, you can change the behavior of PCM per application by
129 writing a command to the proc file. There is a proc file for each PCM
