The Site With the Lamp

Yipeee. After a quite a struggle, the analog TV tuner on the P7131 is working fine with mythtv and tvtime. However I cannot say the same about it's radio. The radio doesn't work at all. The only thing I can get out of it is an entry in /var/log/messages that says "tuner' 1-004b: tuner has no way to set radio frequency".

A google search for the error does not brings up anything usefull. But there was one post in a mailing list that included a patch for the saa7134 drivers.

In fact during my countless searches over the past few weeks I have seen innumerable patches for the saa7134 and other drivers. Many of the posters claimed that they were required to make even the TV tuner work. The truth is that none of them were needed. My kernel is supposed to have support for this card already.

This particular patch though, appeared different and I got the feeling it might address the issue. It's been a long time since I last compiled a kernel. I am very reluctant to go through all that again so decided to apply the patch and compile just the relevent modules.

make M=drivers/media/video/saa7134/
make modules_install M=drivers/media/video/

Once compilation was completed, you need to remove the modules in memory and insert the new ones. The order in which some of these modules are inserted matters (it shouldn't but it does). So I thought, that's the reason that for continuing to get the "tuner' 1-004b: tuner has no way to set radio frequency" message. The only thing left to do is to reboot. What do I see after the reboot?

"tuner' 1-004b: tuner has no way to set radio frequency"
