On 2.6.38 it still fine work and form 2.6.39 to present it is not. I have seen to source's different for BTTV code from 2.6.38 to 2.6.39 and have not seen any functional changes then the problem is generic for radio API. For test I call command "v4l2-ctl -d /dev/radio --all -L" on 2.6.32 and 3.1.4 kernel's versions: ***************** 2.6.32 (OK) ************************* [root@roman ~]# v4l2-ctl -d /dev/radio --all -L Driver Info (not using libv4l2): Driver name : bttv Card type : BT878 radio (ProVideo PV951) Bus info : PCI:0000:01:09.0 Driver version: 0.9.18 Capabilities : 0x00010000 Tuner Video input : 0 (Radio: ok) Audio input : 0 (Radio) Frequency: 1040500 (65.031250 MHz) Tuner: Name : Radio Capabilities : 62.5 Hz stereo Frequency range : 65.0 MHz - 108.0 MHz Signal strength/AFC : 13%/0 Current audio mode : stereo Available subchannels: mono mute (bool) : default=0 value=0 ***************** 3.1.4 (Wrong) ************************* [root@roman ~]# v4l2-ctl -d /dev/radio --all -L Driver Info (not using libv4l2): Driver name : bttv Card type : BT878 radio (ProVideo PV951) Bus info : PCI:0000:01:09.0 Driver version: 3.1.4 Capabilities : 0x00010000 Tuner Video input : 0 (Radio: ok) Audio input : 0 (Radio) Frequency: 0 (0.000000 MHz) Tuner: Name : Radio Capabilities : 62.5 kHz Frequency range : 0.0 MHz - 0.0 MHz Signal strength/AFC : 0%/0 Current audio mode : mono Available subchannels: mute (bool) : default=0 value=0 Regards, Roman
