Public bug reported:
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:
