Post subject: | DVB-S Radio |
In NZ we have a number of radio stations that heve feeds to the satellite where I get my DVB-S Freeview TV channels. In knoppmyth (R5F27) the sound never comes up. I just get a black screen (which is OK as there is no video PID), but the lack of audio makes it worthless It works fine in mythbuntu 7.10 (used as a livecd with knoppmyth as the back end). Does anyone know how I can fix this? Nick |

Post subject: | Same here! |
I seem to have the very same problem. I am running Knoppmyth R5.5. My Hardware is a PCChips Mobo with an AMD Geode NX1750 CPU and 768 MBytes of RAM. The graphics card is an Nvidia FX5200 and the TV card is a Skystar 2. Connected is a Switch with two LNBs (Astra 19° and Astra 28°). Everything else works fine, i.e. TV reception is no problem with both sats. I also tried to play radio via mplayer (e.g. mplayer dvb://"BBC R2") and this also works without troubles. So I think it is not a problem with HW, signal strength or drivers. But in mythtv I get a black screen and a partial lock message (with LmS). I believe this is a mythbackend problem, because in the mythbackend.log I get these weird errors: Code: 2009-07-26 19:25:15.073 Using runtime prefix = /usr

Can anyone steer me towards how to narrow the problem down any further? |

Re you trying to play back the audio over spdif? My digital spdif system won't play it, I guess because of a funny bitrate or something. It plays over analogue just fine. |

Ah that's a different problem then. I don't hear anything, even via analog out (but I do get sound during liveTV or video playback). Didn't try SPDIF out. |
