FM Radio tuner of WinTV PCI (Conexant CX23881-19 chip) doesn't work

[jk]

The card (WinTV PCI, model 34519 Rev J189, using the Conexant CX23881-19 decoder chip) supports analog TV and FM radio, both of which I confirmed to be working in a Windows XP machine. TV also works on linux (Ubuntu 9.10, kernel version 2.6.31-14-generic), but the FM radio tuner doesn't work properly.

The device file /dev/radio0 is there, but every radio application I tried produces only a hissing noise on every frequency and doesn't find any channels. When I start "radio -c /dev/radio0" (from the "radio" package), the tuner frequency shown initially is "2147.", whatever this is supposed to mean. In this setting, it is noticable that there is some radio signal there - it is very faint and unintelligible, but you can tell that there are people speaking.

As soon as I try to change the frequency though, a hissing noise appears which sounds exactly the same on each and every frequency. Also, on no frequency I can set up there is anything resembling the unintelligible speech heard in the tool's initial setting.

I suspect that the code to change the tuner frequency doesn't work correctly for this card.

The dmesg output from the cx88 module reads as follows:

I made another discovery: When I load the module cx88xx with option "radio=51" (I added the line "options cx88xx radio=51" to /etc/modprobe.d/local.conf), I still hear the hissing noise in the initial setting of the radio app (with frequency display on "2147."), but when I change the frequency I get a working radio signal - rather clear and ok sounding - just that it's the same signal no matter which frequency I choose!

[jk (mail-j-k)]

The same behavior (one station on all frequencies) happens with radio=60 and radio=78. I couldn't reproduce this behavior with any other of the defined card configurations.

Hi jk,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 475734

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

I have a similar problem running Ubuntu 10.04 and HVR-3000 card.
DVB-T Tv works fine with Kaffeine.

I installed Gnomeradio 1.8 (through Software Center), it finds the device /dev/radio, but scanning the stations gives no result.

So FM Radio doesn' t work.
