The cx18 driver seems to be working wonderfully, other than I get no audio.
$ cat /dev/video0 > test.mpg
$ mplayer test.mpg
[snip]
Audio: no sound
[snip]
So it's looking like it's not finding any audio at all, it's not low or
anything.
I read it only supports mono so far, so let's check that:
~$ v4l2-ctl -IT
Video input : 0 (Tuner 1)
Tuner:
Capabilities : 62.5 kHz multi-standard stereo lang1 lang2
Frequency range : 44.0 MHz - 958.0 MHz
Signal strength : 100%
Current audio mode : mono
Available subchannels: mono
~$ v4l2-ctl -D
Driver Info:
Driver name : cx18
Card type : Hauppauge HVR-1600
Bus info : 0000:02:00.0
Driver version: 65536
Capabilities : 0x01070001

~$ v4l2-ctl -l | grep -i audio
audio_sampling_frequency (menu) : min=0 max=2 default=1 value=2
audio_encoding_layer (menu) : min=1 max=1 default=1 value=1 flags=update
audio_layer_ii_bitrate (menu) : min=9 max=13 default=10 value=13
audio_stereo_mode (menu) : min=0 max=3 default=0 value=0 flags=update
audio_stereo_mode_extension (menu) : min=0 max=3 default=0 value=0
flags=inactive
audio_emphasis (menu) : min=0 max=2 default=0 value=0
audio_crc (menu) : min=0 max=1 default=0 value=0
audio_mute (bool) : default=0 value=0
The only strange thing showing up in dmesg is:
[158086.417606] cx18-0: i2c ID 0x00000000 (gpio) not found for cmd 0xc0185650!
repeatedly.
This is on Ubuntu 8.04, 2.6.24-16-generic #1 SMP Thu Apr 10 12:47:45 UTC 2008
x86_64 GNU/Linux
Any help would be greatly appreciated.
