"Digital" radio (1 Viewer)

First I would like to say that MP is really cool! It's not finished yet, but already much better for the tuning of the TV compared to SageTV and BeyondTV (possibility to enter the frequency) :)

Could 'digital' radio playback be supported? With this I mean the use of the radio trough the MPEG encoder like for television. This is needed for some cards, because there are cards that don't have an analog audio connector. Like the AverMedia M150. This card has the same MPEG encoding chip as the Hauppage PVR 150 and 250.
Currently MP tries to find an AUX plug on the selected sounddevice. Like this:

Code:
23-12-2004 0:06:03 RadioGraph:Link the CaptureGraphBuilder to the filter graph (SetFiltergraph)
23-12-2004 0:06:03 RadioGraph:Add graph to ROT table

23-12-2004 0:06:03 Player.Play(90600000.radio)

I already looked into this problem and found a very easy solution using Graphedit. It is just the same setup as for TV, disconnect the video pins and set the tuner to radio (That is currently working as I see the log above). I can send the .gph file if needed (uploading is not allowed on this forum).

I hope this can be added. It would also introduce the possiblity to implement timeshift radio for these cards.

And of course many thanks for MP! :D

    I have the Dvico DVB-T and it has 2 Digital Radio channels....in Australia...they are SBS and ABC. They play 24/7 and sparkling crystal quality...so it would great if these could be implimented....the tuning and playback would be required i guess

    Nice to see it now in version 1.0.3. Unfortunately version 1.0.3 doesn't work correclty on my system yet, but I didn't had much time to find the problem.

    BTW, realized I never replied back on this one, in case anyone else runs into it. @Stéphane Lenclud Got me pointed in the right direction. My TV Has an option HD Deep Color Mode, turning this on or off will get the desired results.
