Hello, 31 kernels and boots later I have worked out how to detect and setup stereo/mono(/bilingual) mode in case of the german stereo system. There is a significant difference to the nicam system used in some other countries. With a nicam source the 3410d is able to do nearly everything by itself. In the german B/G FM mode one has to read out the stereo level register and set the output matrix to stereo, mono or bilingal mode. After puting the 3410d into autodetect mode one has to wait about 220ms to a maximum of 500ms for a result of the autodetect. Depending of the value one will do the switch to stereo and set some spatial effects like wider stereo base or pseudo stereo in case of mono station. The patches are again available at http://www.radio-do.de/~fn/bktr.patch.gz They are mainly for german WinTV owners, but should not break the non german cards. Please have a look at the patches and give me responce in case of errors or if you have just recommendations. The next step should be to set up a set of ioctls to make setting of the effects and such more easy at application level.
