- 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

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
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.
