[LAU] jackdbus in playback mode

Hi all, I need to start jackdbus in --playback only mode as this seems the only way to avoid xruns on my setup. Is that possible? Please find below my jackdbus configuration. thank you, Stefano <jack> <engine> <option name="driver">alsa</option> <option name="realtime">true</option> <option name="realtime-priority">80</option> <option name="clock-source">0</option> <option name="port-max">256</option> <option name="sync">true</option> </engine> <drivers> <driver name="dummy"> </driver> <driver name="netone"> </driver> <driver name="alsa"> <option name="capture">none</option> <option name="playback">hw:0</option> <option name="rate">48000</option> <option name="period">128</option> <option name="nperiods">3</option> <option name="duplex">false</option> <option name="softmode">true</option> <option name="dither">t</option> <option name="shorts">true</option> <option name="midi-driver">seq</option> </driver> <driver name="firewire"> </driver> <driver name="loopback"> </driver> <driver name="net"> </driver> </drivers> <internals> <internal name="netadapter"> </internal> <internal name="audioadapter"> </internal> <internal name="profiler"> </internal> <internal name="netmanager"> </internal> </internals> </jack> ~
