I can reproduce this here with FC5 on an Asus P5B with ADI-1988B and Hauppauge WinTV. Neither vmlinuz-2.6.17-1.2187_FC5smp nor 2.6.18-1.2189.fc5smp (from updates/testing) is working. The TV card generates a signal on it's line-out so there must be a problem with the mixer. The problem has been fixed between 2.6.18-1.2693.fc6 (didn't work) and 2.6.18-1.2784.fc6 (now works). I didn't try any kernels in between those two, so I can't say which version contained the fix. Also, stereo sound is now working correctly, so this bttv version also fixed a separate problem where switching between two stations, one with stereo and one with mono, would lose the sound entirely, but could be corrected by selecting Setup -> Input Configuration -> Preferred Audio Mode and switching from Stereo to Mono and back again. I still have the problem with the stock FC6 kernel (2.6.18-1.2798.fc6) which is newer than 2.6.18-1.2784.fc6. Can someone reopen respective fix the bug, please? Thx! I'm also using 2.6.18-1.2798.fc6, but it still works for me. After a reboot, TVTime gives a "No Signal" error until I do the following: rmmod bttv bt878 modprobe bttv and sometimes this needs to be done more than once (race condition?). But the sound does work after this magic incantation. Ok, thx for your comment but this does not help in my case. But nevertheless even if this would work it does not fix the line-in problem. The output of the TV Card (which definitely has a signal) is connected to the line-in of the on-board sound hardware but I do not hear anything. I played long time with alsamixer but with no success. Reloading bttv related modules cannot fix this because they are not related to the on-board sound hardware. I got it working: I had to add a module parameter: model="3stack" e.g. options snd-hda-intel index=0 model="3stack" After this I enabled the analog mixing and then was able to hear sound from tv card. There are other models avaliable. I just looked at the driver source to get this idea. |
