When adding codecs to a card, all the controls of each individual codec are visible as controls for the complete card. But how does one handle the case of multiple codecs of the same type, for instance two identical codecs being used in TDM mode to create a multi channel card? Is there some method for resolving the fact that the control names naturally conflict? Or is this expected to be resolved in the machine driver? Currently I've been using simple-card, but perhaps this type of configuration is too advanced to be resolved for that, and a specialized machine driver is needed? /Ricard -- Ricard Wolf Wanderlof ricardw(at)axis.com Axis Communications AB, Lund, Sweden www.axis.com Phone +46 46 272 2016 Fax +46 46 13 61 30
