And if I specify my analog output in the "slavepcm" attribute of the a52 plugin, I can hear a "pop" sound when I do the switch. So yeah, I guess it sent a bit to data to it when I switch.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
