Hartmut was aware of it too, but who likes to work on > analog radio these days ... I do. As we embedd these cards on our servers we'd like to add this = feature to our products (analog to digital streaming servers). Anyway, this is a feature of the card which is lacking under Linux so = the question of who is interested in analog radio is not a good = question. The question of why not going as far as possible when = supporting a card is a good question. So yes I am not afraid of saying I'm interested in analgo radio :) > = > It is not implemented yet, if it should be related. > = > Cheers, > Hermann > = > = > = Ok so if I get it right, what you're saying is that stereo radio isn't = working on HVR 1300 with FMD1216MEX but mono radio is working ? If yes = I'd like to know how ... shouldn't I just set frequency to /dev/radio, = then get it from /dev/dsp ??? This for me isn't working and providing = only noise. Now if you tell me this is just not implemented yet, then how could I = help you to implement it ? If it's not scheduled to be implemented one = day then I might be able to work on it at my office (maybe not me = directly but one of my coworkers). Btw I tried on my KNC TV Station DVR (FM1216ME MK3, saa7134, saa6752hs) = with no success : if I tune to an analog TV station through /dev/video, = I will get sound from /dev/dsp. Then I tune to a radio through = /dev/radio ... but I still get the TV sound from /dev/dsp ... -- = CAND Frederic Product Manager ANEVIA _______________________________________________ linux-dvb mailing list linux-dvb@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
