 |
|
Ever since i upgrade my kernel from 2.6.13 to a 2.6.15/16/17 kernel, tvtime still gives me screen but no sound any more. I didn't changed any settings on my Pinnacle PCTV Rave and it is still being detected correctly. Anyone knows what the cause of the problem is ?

WHen you have a lead connected to your soundcard's line-in, can you check if it is not muted are the volume set to 0 by accident? Also check if tvtime is using the correct input where you connected the lead to.

with kernels >2.6.15 i get a similar problem. Instead of no sound i get just noice. My fix is to do a:
| Code: | rmmod bttv
modprobe bttv |
and then it works just fine like before... If someone knows what might happen, please share..

Well i checked that several times, and again, like 10 times allready, and i am pretty sure that is not the problem. I even have static noise coming from the TV card, so i am pretty sure it is connected correctly and not muted.

Well that would imply that i need to switch from a built-in kernel to a modular kernel. Which i for personal reasons don't prefer. However there seems to be a problem that is causing it, and that should be fixed. I tried the Vanilla sources yesterday, insted of the gentoo-sources, but the problem remains the same. All newer kernels only produce static noise. I will set up a modular kernel and try what you suggested, but i don't see it as a permanent solution if it works though, |

This should not be true. I have a bttv based card running 2.6.17.1 and it works fine. What sort of static noise is it? If you're cranking the volume up really loud at one place but have it set to 0 or muted (which mine was by default after upgrading) somewhere else, then it will give static noise. I'm using tv as a module now because I can load just 2 modules to get all the others loaded, but it works fine built in. Do you have audio enabled under the V4L section and device drivers > sound > alsa > pci cards? EEPROM reader? |

i know that that solution is not permanent.. but it works. The only thing i can think of is that it's how udev loads the module at startup, but i didn't find what's wrong with it yet. Who knows... maybe a clean installation would do it, but i can't do it now..

I have the same problem, i'm with 2.6.14-gentoo-r5 from january and all the newest kernel didn't work...hours lost searching in forums and internet for nothing...
At many people the module don't recognize the right tuner, but in this case the tuner is right:
| Code: |

I tried everything, loading the module with different configuration...help  |

Ska`, I noticed the irq changed from 18 to 21. Can you pass pci=routeirq to the kernel and see if this solves your problem?

I can comfirm that 2.6.14-gentoo-r5 was the last kernel that worked. I'll try with pci=routeirq and report...

Situation here:
2.6.17-gentoo-r4 -> don't work, same bttv output again
2.6.17-gentoo-r4 with "pci=routeirq" -> also same error
But i'm not sure about my lilo.conf, i placed "pci=routeirq" here:
append="video=radeonfb:1280x1024-32@75 splash=verbose theme:emergence pci=routeirq"
Is it right? |
