# jacklaunch(1)

launch sound program as JACK client

## NAME

jacklaunch - launch sound program as JACK client

## SYNOPSIS

**jacklaunch** application-name  options

## DESCRIPTION

The **jacklaunch** command can be used to turn sound programs that are accessing the OSS sound system into JACK aware applications. It is using a library called libjackasyn, which is preloaded with the LD\_PRELOAD environment variable.

The same effect can be achieved by setting the LD\_PRELOAD variable globally.

export LD\_PRELOAD=/usr/lib/libjackasyn.so.0

In this case all of the programs using the OSS API will be run as JACK clients if the jackd is started. If jackd is not started they will behave in their normal way and use the OSS sound I/O directly.
