I think I found the bug that caused the FM radio not being stereo in 29xxx devices. The bug was (not so) surprisingly in the msp3400 module. Thankfully, this bug is already fixed by Hans Verkuil's commit ec5a9f0bca164ccf62399b37394d7a98f7e9be3d in v4l-dvb repository. If you have a recent kernel (say >= 2.6.18/19) and you don 't want the whole v4l-dvb repo, you can isolate this patch using hg export 4982 >From the commit log of this: "The wrong matrix was used when an external input was selected instead of the tuner input. The rxsubchans field was also not initialized to STEREO for an external input. And finally the msp34xxg_detect_stereo() should not try to detect stereo for an external input, that code is for the tuner input only. Together these bugs made it hit 'n miss whether you ever got stereo out of the msp3400 for an external input." This, together with the fact that as far as msp3400 is concerned, radio is just an external input (SCART2 IIRC), explain why this bugfix resolves the radio problem. Thanks Hans for fixing this :-) -Pantelis P.S., I also applied the "mplayer pan" test to tv input and (un)surprisingly I found this to be mono as well. That could be the station though, but I 'm sure I 'll have to investigate more :-( _______________________________________________ pvrusb2 mailing list [email protected] http://www.isely.net/cgi-bin/mailman/listinfo/pvrusb2
