OSS device

From the ALSA wiki

Jump to: navigation, search

One of the aims of ALSA is to provide full compatibility for OSS applications. ALSA has a powerful OSSEmulation which provides the following OSS devices:

PCM

Mixer

MIDI

Sequencer

Probably not supported:

X is the card number from 0 to 7.

Unlike actual OSS, ALSA cannot use device files more than the assigned ones. For example, the first card cannot use /dev/dsp1 or /dev/dsp2, but only /dev/dsp0 and /dev/adsp0. In an OSS installation, symlinks without the trailing device numbers are often used to connect to devices; for example, /dev/dsp might be a symlink pointing to /dev/dsp0.

Some distributions have the device files like /dev/midi0 and /dev/midi1. These are not for OSS. They are for tclmidi, which is a totally different thing.
