+++ This bug was initially created as a clone of Bug #680813 +++

Description of problem:

The original kernel package in Fedora 14, 2.6.35.10-74, included support for the FM tuner for the Avermedia GO 007 FM card in the saa7134 module that worked fine, as did the kernel package in previous Fedora versions. I followed the recent kernel upgrade to 2.6.35.11-83 and found the FM tuner support no longer working, although the TV tuner continues to run fine. A /dev/radio0 device is still created, and can be opened, but an ioctl call that has worked for years now returns an error code.

Version-Release number of selected component (if applicable):

2.6.35.11-83

How reproducible:

Always

Steps to Reproduce:
1. Upgrade to 2.6.35.11-83
  
Actual results:

struct video_audio audio;
radfd = open("/dev/radio0",O_RDONLY);
status = ioctl(radfd,VIDIOCGAUDIO,&audio);
  returns an error status with the "Invalid argument" error number

Expected results:

Current FM tuner audio state returned in audio structure.

Additional info:

Booting back into 2.6.35.10-74 allows the FM tuner to run as before.

Mauro, any ideas on this one?

Can you provide dmesg output after a fresh boot for the non-working kernel? You might also want to try this kernel here:

http://kojipkgs.fedoraproject.org/packages/kernel/2.6.35.11/85.fc14/

It carries a tuner-related fix that *might* be relevant here as well...

Jarod,

It is simple: VIDIOCGAUDIO is an old V4L1 call. V4L1 API were removed.

John,

You need to use an application that works with V4L2 API. You can use "radio" application shipped with xawtv. I've ported it recently to work with the new API. I just built a new package for rawhide at:
