Hi Mauro,
You've been working on cx88 for a long time. Can I ask you
something? I have a cx88 based card and I tried to get audio coming
from "Line In" of my card. However, it seems like the audio always
comes from TV input. I looked into the code and it seems like
VIDIOC_S_AUDIO is not working in cx88. Can you help please?
Thanks.

The better is to ask such questions on linux-media@vger.kernel.org. Anyway, the
issue is likely due to a wrong entry at cx88-cards for your board. In order to
fix, someone with your board (probably you)should get the proper GPIO pins for
your device. Please read the following wiki articles:

Cheers,

In Linux cx88 driver, is it possible to stream audio only without
video Risc engine running? If so, what tools/players and commands can
I use to stream audio only from cx88 card?
I appreciate for all your help.

Sorry for not answer before. I got flooded of emails.
AFAIK, the cx88 internal RISC processor is responsible for moving the sampling
data. I don't think you can have the device working without uploading the risc
firmware.
