| Post subject: | newbie question for mythtv |
I have the following hardware for myth: AMD 1.15Ghz, 256M ram 40G harddisk Leadtek win 2000xp expert tv turner card on board via sound card After reading mythtv doc and others I still have these problem with my turner card. I have been able to watch tv with xawtv but not with mythtv. But has no sound. I can listen to cd with the cdrom sound cable to the motherboard. I unplug the cdrom cable and plug the sound cable from the tv card to the motherboard. But still have no sound. When I use mythtv, there is only green blank screen and noise of the harddisk storing data. I am in Australia. I have the set up the video source to au and device to /dev/video, sound to /dev/dsp. Would be much appreciate if someone can point me to diagnose the problem. Cheers David Kwok |

Less I'm mistaken, the "expert" doesn't work with Linux. |

It does, I think since xawtv is working. The driver used is cx88xx driver. You mean mythtv does not support it? |

I think he was remembering someone who was trying to use it with the bttv driver before. if it works with xawtv then it should work with mythtv. more than likely to get sound you will have to use the cable that goes to the line in on the sound card. not one that plugs directly to the motherboard. as for the green screen do some searching, it's been discused quite a bit, but I can't remember what all the possible causes are off the top of my head. |

When I turn on the mythtv, is there any vital sign to see if it is getting the right device, etc? |

it's going to use whatever device you assigned it to during the setup. |

Is there any way to see why mythtv is not working in this case? |

not really. my suggestion would be the same search the forums for green screen or green or something like this. there are several causes for this, my gut would tell me it is something to do with either pal or resolutions, but I've not worked with pal and the forum posts would help you more. |

autoinstall won't work with sata you might be able to use manual install, but that might not even work, because many sata drivers are not included in the knoppmyth kernel yet. |

Currently no SATA modules are in the kernel. R5 will have the SATA support, but it certainly won't be ready in a week. |

| Post subject: | Green Screen |
I have the exact same problem with my machine and the current version of Knoppmyth. My screen is green when I try and watch TV with Myth. Everything else works (the program guide, Weather, CD tunes, but no TV. So I decided to test my card this weekend with Mandrake 10 and 10.1 and iI tried XAWTV and Xine and the video works, but I get no sound This is interesting because I would have guessed that it would have been the opposite. But this was not the case. My WinTV-FM (BT878 chipset with Phillips F1236 FM tuner) is plugged into the MIC connection on the onboard motherboard sound.. During my due dilligence I found a very valuable post at http://www.linuxforum.com/forums/index. ... opic=97722 What this basically tells me is that the Kernel is having trouble even thought it is detecting the BT878 chipset it is not quite detected correctly. More specifically the audio driver of the BT878 is conflicting with other boot up processes. Here is what needs to be changed to fix this problem I think #CONFIG_SND_BT87X is not set needs to be changed to CONFIG_SND_BT87X is not set Unfortunately Debian and the Kernal is not my strong suit. I'm not sure if it iis possible to edit the modules.conf or if this is considered a Kernal recompile. I could use a little help to get this fixed. I have a lot of computer experience but not a lot in Debian. I have never recomipled the Debian Kernal before. and don't know exactly how to do it. I have recomplied Red Hat 7.1 so I get the general concept.. Here is my setup Athlon 2700+ Biostar M7nCG Nvidia Quadro Crucial pc2100 256mg WINTV -FM Model 44811 |

| Post subject: | Solution to green screen |
Well after about a week or so of fooling around with my knoppmyth setup I am pleased to have a solution to the green screen problem that plaged me for the past week. Basically everytime I tried to watch Live TV the screen was green with black static across the top fifth of the screen. However when I lauched XAWTV it showed one channel. Athlon 2700 Corsair PC2100 256mb WinTV FM model (BT878 Chipset Phillips F1236 FM tuner) Biostar M7NCG motherboard I pulled the Nvivia Quadro Card in favor of onboard GForce 4 MX built onto the board. I did this to try and isolate the issue but it really didn't make a difference. I installed the NVIDIA graphics driver with the command install-nvidia.sh which must be run as root (Ctl-ALT F1 to login and Ctl-ALT F7 to go return). First, I checked the logs and they appear to be in good shape by checking the WINTV card and Sound Options for errors. With BT878 there are BTTV options instead of IVTV option. They are located in /etc/mythtv/modules/bttv. This site has a lot of good info to fix cards that are detected improperly http://linux.bytesex.org/v4l2/bttv.html Knoppmyth has the latest version of the driver so there was no need to update it. As root check the following cat /var/log/messages | less cat /var/log/syslog | less cat /etc/modules.conf | less Lspci -v | less cat grep /proc/pci grep -rs sound-slot /etc* So with the logs looking good I figured it was time rebuild the kernel. In this case you just need to rebuild it you don't need to change it at all. Exit Myth Control-ALT F1 Log into the console as Root Enter Root Password cd /usr/src/ tar xvfj linux-2.4.25-chw.tar.bz2 make dep make clean make bzImage Reboot the system Close out myth Open Xterm type AUMIX or ALSAMIXER Select the sound input that your plugged into and leave the volume for that source off. (ie the red one MIC or the Blue One Line In). Double check that the mute is not on. The main volume is on at a halfway setting. Launch Myth and test out Live TV. Good luck it worked for me.... |
