Hi,

the chip CX23103 that is used in various devices sold e.g. in germany works 
with the cx231xx stock driver.

The author of that driver is not reachable via the email adress stated in the 
source file: srinivasa.de...@conexant.com
[ host cnxtsmtp1.conexant.com [198.62.9.252]: 550 5.1.1 
<srinivasa.de...@conexant.com>:  Recipient address rejected: User unknown in 
relay recipient table]

In drivers/media/video/cx231xx/cx231xx-cards.c the struct usb_device_id 
cx231xx_id_table[] needs these lines added:

   {USB_DEVICE(0x1D19, 0x6109),
   .driver_info = CX231XX_BOARD_PV_XCAPTURE_USB},

While the change is minimal due to the fact that no real technical 
documentation is available on the chip the support was guessed - but worked for 
video.

The videostream can pe played using mplayer tv:///0  - proof: 
http://streibelt.de/blog/2013/06/23/kernel-patch-for-cx23103-video-grabber-linux-support/

However when trying to capture audio using audacity while playing the video 
stream in mplayer my system locked (no message in syslog, complete freeze). 


I posted this one month ago to this list without any reaction so I ask if this 
is the correct way to get that grabber really supported.

I am willing to do any tests neccessary and try out patches.


/Florian
