Making it Work
Basic support since kernel v4.6.
Assuming video device is `/dev/video1` and audio device is `hw:2,0`:
- under vlc (recommended):
vlc v4l2:///dev/video1 :input-slave=alsa://hw:2,0 :v4l2-width=720 :v4l2-height=576 :live-caching=10
NOTE: vlc apparently can't deduce all acquisition parameters on it's own, so we have to specify width/height parameters. Also, a bit of caching is necessary to have proper audio/video. Here I use 10ms to have minimal latency.
- under mplayer:
mplayer tv:// -tv device=/dev/video1:alsa:adevice=hw.2:audiorate=48000:forceaudio:immediatemode=0
NOTE: we need to force audio, disable immediate mode and set proper audio rate to have sound. However, I can't get non stuttering video when I enable audio, which is not that great for video-gaming purpose.

Status
On a Debian Stretch with a 4.7.8-1 kernel, the Grabby v3 works with ffplay and qv4l2, but the picture quality is not very good, sometimes some lines or the whole display "jumps". And with some video sources captured on Linux, there is more noise than signal while those same video sources display ok with the Windows drivers.
Audacity can capture the sound properly but qv4l2 sound output stutters a lot and keeps displaying the following errors :
ALSA lib pcm.c:8251:(snd_pcm_recover) underrun occurred ALSA lib pcm.c:8251:(snd_pcm_recover) overrun occurred
Firmware
The driver loads v4l-cx231xx-avcore-01.fw into the Grabby.
The windows drivers CD also contains a firmware with the following MD5 hash : a9f8f5d901a7fb42f552e1ee6384f3bb
Drivers
The Grabby v3 use the following kernel module : cx231xx
