Radio not playing all channels

reprive · 2006-12-20, 23:42

I discovered MediaPortal this week and decided to give it a try. After some experimenting with the various configuration options I have most of it running (config below) and I've become quite enthousiastic. Great work! One thing I can't figure out (but suspect to be codec related) is how to get all DVB-C radio channels to work while also keeping TV audio.

First I had an issue with mute TV channels but this was fixed by using the DScaler audio decoder in stead of the nVidia one. However now a lot of radio channels are mute (also with nVidia). I then switched audio decoder to AC3filter which gives sound but it is stuttering (some kind of regular hiccups) on all radio channels and makes some TV channels go mute. Couldn't see any irregularities in GraphEdit but I must admit I don't know exactly what to look for as I'm certainly no expert in this area, but at least all boxes are connected and run from capture to rendering.

I've done some browsing on the support forum and found some potential solutions (e.g. AC3-PID for television) but none seemed to be applicable.

Strange thing is that with Showshifter, which I also have on the machine (and intend to stop using if I get this all fixed), the radio as well as the TV sound are fine on all channels. I'm a bit hesitant to play around with codecs etc. because that may mess up Showshifter which I don't want to do just yet.

Attached a logfile, what I did is start MediaPortal, go to TV and view Sailing Channel for a while (worked fine) then go to Radio and listen to 3 voor 12 BPM (also works) and then switch to Radio Donna (mute). Interesting to note (don't know if it's a coincidence) is that all channels with working sound are on the same frequency. I've been looking at the logfiles myself as well and I'm not sure what the 'Harder than Hell' reference comes from (e.g. EPG log), it's also a radio channel but I didn't use it in this session.

I've done all I could think off, and I'm a bit stuck now. I would appreciate if someone could help me out.

Thanks in advance for any suggestions!

Same here... I installed a Twinhan CAB CI card yesterday and I can play some radio stations (e.g Q-Music) but others remain mute (Studio Brussel). Didn't test them all yet (no time) but Studio Brussel definitely plays fine with the TwinhanDTV program and not in MP.

On the TV side I got no sound on EuroSport until I switched to DScaler.

Same here... I can't even get DVB-C radio channels tuned when autotuning!! Previously, this was not a problem, but I couldn't get any sound, whatever channell I chose.

I'm going to give it a try once more by choosing one channel, then select every available codec on my system (and I've got a few... :-)).

Let you know if anything positive comes out of it.

Tried it guys. But unfortunately, I got no radio channel when auto-tuning....

Sorry.

guido66 · 2007-02-12, 23:02

Exactly the same radio problem over here. Thanks for the tip on the DScaler audio decoder, at least I now have sound on all the TV channels

I could be barking up the wrong tree but could it be due to different bitrates? Maybe lower bitrates aren't playing? Any thoughts anyone?

I tried the nVidia PureVideo codec (trial version) as TV codec (both video and audio). All radio channels play fine now. Seems that some stations come in a format that DScaler or MPA can't handle (?) I have no idea how to see the actual format that's coming in (codec, bitrate...) from within MediaPortal, is this info available in the logfile?

Just tried the same, but the purevideo codec didn't work for me. All TV channels had sound, but most of the radio stations remained silent, exactly the same as with the DScaler codec.
