The saa7146 is a generic chipset that is used on quite a few different cards. You only compiled and inserted the generic driver core for the saa7146. > Does the saa1746 module plays as a common driver for all the device > with that chip? No. You are missing the extension module for the specific card you have. For example, if you have a so-called "Multimedia eXtension Board", you need to insert the "mxb.ko" driver as well. Please tell me what kind of card that is, ie. brand, manufacturer, card id etc. so I can tell you if there is a driver that supports it or not. > Thanks! Best regards Michael.
