Manual Reference Pages - OSS_USERDEV (7)
oss_userdev - OSS client/server audio pseudo device.
This audio device is not designed to be used as-is by the users. It requires
a specially designed server application that implements the actual service
(please see the OSS programming documentation for more info). The server
application will then create the audio devices that can be used to record
and/or play audio.
The oss_userdev driver is a special purpose loop back audio device that can be
used when implementing OSS audio devices based on a server running in the
If this option
is set to 1 then OSS will create separate client device nodes for each
instance. Applications will have to open the right device nodes. This
alternative is best when oss_userdev is used to create different kind of
services in one system. In this way for example a VoIP link can be accessed
by opening a different device node than when opening some other service.
By default (0) common client device node (/dev/oss/oss_userdev0/client) will
be created for all server instances. The clients will then get directed to the
right instance based on some search criteria (for example UID). This
alternative is best when using single server application that can serve large
number of different sesions.
