Hello ! I have successfully running video on this card but can't obtain the sound. Output of "v4l2-ctl --log-status --device=/dev/video0" command is:

As I understand the card can't detect audio system:
cx25840 1-0044: Detected audio standard: no detected audio standard
cx25840 1-0044: Audio muted: no
But when I'm rading from /dev/video0 I see the audio PES packets (0xc0
PID). It's looks like this packets is "fake" or "silence". This is first
64 bytes dump of this packets:
0x0 0 1 c0 7 ec 80 80 9 21 10 43 64 a9 ff ff ff ff ff fd b4 0 bb 11 11
11 11 11 11 dd 11 11 11 24 92 49 24 92 51 0 0 35 0 e aa aa aa aa aa aa
aa aa aa aa a1 86 cf 3c 30 c3 b 6d aa aa
And of course there is silence in headphones.
I'v trying to get registers with command "v4l2-dbg -R
type=i2cdrv,chip=cx25840,min=0x805,max=0x809 -d /dev/video0" and I'v get
following error messages:

and following messages in dmesg:

I'v trying to change audio_conf with following command "./v4l2-dbg -r
chip=cx25840,reg=0x808,val=0x1f -d /dev/video0". This command completed
successfully but nothing is changed.
Please, help to solve this problem.
Thanks !
