It is either a problem with the analog tuner driver or the driver for the MSP chip. Either way there is not much you can do to fix it without someone fixing the broken driver.

Please provide the output of
v4l2-ctl -d /dev/videoN --log-status
when using ivtv-radio to tune to FM radio

That might help narrow down the problem driver.

Andy

Hi,

Since I upgraded to Ubunutu 11.10, ivtv-radio stopped working.
In particular, it now produces high-pitched noise.
The kernel version is 3.0.0-13-generic #21-Ubuntu.
If I boot an older kernel (2.6.38-12-generic #51-Ubuntu),
ivtv-radio does work.

TV capture works for both kernels.

Any ideas how to solve this problem (except for simply booting
the old kernel)?

Thanks,

It's an ivtv bug which has existed since 2.6.39. Although the ivtv driver
claims to support radio, it fails to enable the radio function of the tuner (a
simple bit-flag error iirc). I'd forgotten about it, but I do have the patch
somewhere.

Oops. Yes you sent that to me in september IIRC. Ill repost it when I get back home, if you can't find it.

Ian's patch, which he sent me on 12 Aug 2011, is available here:

http://git.linuxtv.org/awalls/media_tree.git/commitdiff/110c7cd65328c6ed336daeffefad57aed3e4f028

I suppose I havent't been a very responsive maintainer lately. :(

Does this really mean that radio is broken for all ivtv devices in Kernel
2.6.29(.x) and 3.0(.x) ?
I am wondering why there are no more bug reports.

Any chance to get this patch in Kernel 3.1?

Greets,
Martin

Probably. I have not searched for the affected versions. I will guess
that the rework of the tuner and tuner-simple modules, and how those
modules handle the mode_mask, is what introduced the problem.

I myself use FM radio alot, but not with the latest kernels.

Mauro has it queued up for the 3.2 merge window:
http://article.gmane.org/gmane.comp.video.linuxtv.scm/11388

I think I missed my last chance for 3.1.
Linus announced 3.1-rc10 (!) on 17 October:
