Avl is right, mplayer does still work and also kradio. So the trouble happens in the v4l1 compat layer. Symptoms are, that you just have loud static noise and tuning has not any effect. Also no signal and/or stereo detection. "fm" gives now "ioctl VIDIOCGTUNER: Invalid argument". qtradio Using v4l Video4Linux detected 87 - 108 SIGNAL = 0 SIGNAL = 0 VIDIOCGAUDIO: Ungültiger Dateideskriptor VIDIOCSAUDIO: Ungültiger Dateideskriptor VIDIOCGAUDIO: Ungültiger Dateideskriptor VIDIOCSAUDIO: Ungültiger Dateideskriptor Tested on old style simple tuners, some tda9887 stuff and tda8275a/tda8290/saa7131e, on both x86 and x86_64, with some 2.6.29 and some 2.6.30.
