| Post subject: | No sound in live TV or recordings with PVR-250 |
Just installed the latest KnoppMyth, after dabbling with Sage TV for a while. When I watch DVDs I get sound (although it is stuttering and out of sync with the video). With live TV or recordings I get no sound at all. I have this vague memory that when I last installed KnoppMyth some months back I had to delete a line of code somewhere and recompile a component to get the sound to work but now I don't remember. Hardware: Asus Pundit, P4 2.4GHz, 512Mb RAM, PVR-250, Linksys NIC (the on-board Broadcom NIC I had to disable; the driver module with the new KnoppMyth freezes up the whole system after an ifconfig of that NIC). Can someone remind me what the secret is here? |

Recompile ivtv. In the future, please search the forum before posting a question. |

does sound work when playing music or videos(not livetv or recorded from the video plugin)? if not then you have a bigger problem than ivtv and need to fix it first. |

is ivtv just completely broken in R4v4.x or is it people with the newer pvr250's or what? I've never had to recompile ivtv, of course I am using an upgraded R4V3 because of kernel problems. |

well that was my question. I don't remember having all these people having the sound problem with ivtv in the R4V3 days, but it may just be that more people are getting the pvr250's with the newer chips on them now. |

Xsecrets I think it's just R4V4 or maybe R4V4.1. I had a R4V2 install and never had to recompile ivtv, but I did with R4V4.1. It's quite easy to fix, search the forum and you will find the answer. |

Why do you want to install R4V3? That sounds like a lot of work to fix this problem. From what I have read the only problem you have is the sound and the fix is VERY easy. It took me less than a minute to search the forum and find the answer. I don't mean to sound rude but you are going to have to do some work to get a MythTV install exactly how you want it. And personally I would rather learn how to fix things then I will have a better understanding of what's going on. I don't reply to a lot of posts but I have read this forum everyday for a while and I know that Cesman and others get sick of people asking for help with a problem that is easily solved with a search of the forum. Anyway I am done preaching and I have included the fix below. Code: cd /usr/src
# The ivtv compile needs the src files. tar xvfj linux-2.4.25-chw.tar.bz2 cd /usr/local/lib/ivtv/driver make clean # I suppose I could have used 'make install' but I was testing # and didn't want to add to my problems. make cp msp3400.o /lib/modules/2.4.25-chw/kernel/drivers/media/video/ # And answer yes to overwrite the existing file. # Then, if you don't like extra files just lying around: cd /usr/src rm -rfd linux-2.4.25-chw # to delete the source files previously extracted. |

i did find that code earlier.. i just wasn't sure if it was what i needed and was scared to poke around where i didnt belong. I understand all of your frustrations, and i read enough short comments by the moderators to understand that there are a lot of SLOW people like me who are out of their league with linux. thanx for your help in confirming that was the code i needed and your reminder to me and others that there can only be so many questions that have not been asked thus far. you can lead a person to knowledge but you cant make them think.

Yes I am 99% sure that is the fix you needed. I have installed MythTV quite a few times because I messed things up and I just cringed when I heard that you were going to install an older version when I was pretty sure a 5 minute fix would get you going. Again I didn't want to sound rude I just wanted to let you know that some people get impatient with users that don't do a search first. Also sometimes you are not always sure what terms to search for to find the answer to your problem, I have been there and I am sure I will be there again someday when a new version comes out and I decide to wipe my machine to have the latest and greatest version of Knoppmyth. I can assure you that most people if not all are more than willing to help you out if you have a problem. If you follow the instructions that I gave you closely you will not screw anything up even if it wasn't what was needed to fix the problem. Once you have a good running MythTV machine you will wonder how you lived with out it. |

i had the same problem and the fix above worked for me too. the theory about it affecting never pvr250 kinda gets shot down. i have one of the older pvr250s. i is actually called the freestyle and has a heatsink on the encoder chip. anyway, it's older. |

| Post subject: | different sound issue |
After a fresh install of KnoppMyth R4V4.1, sound in all other MythModules (DVD, Video, Music) works fine, except sound from Live TV. Common problem it seems. I know the solution is well noted (recompile IVTV) and that fix worked fine for me when using the PVR350 output for TV. However, now I am trying to use the TV-out of my NVIDIA card. Anyways, when I recompile IVTV...exactly like the instructions posted to this forum, when I go to watch TV through my NVIDIA card (not the PVR, again all is fine when using the PVR-out), mythfrontend immediately quits! No picture...no sound....no myth...I can immediately relaunch the frontend but the WatchTV button quits the program....anyone else experience this. |
