> Hello All,

> Has anyone had problems getting an SAA7134 TV Tuner card working? 
> Mine is not being detected as an audio device, and I'm not sure what

> card is a Compro VideoMate TV Gold Plus which uses the SAA7134 
> driver (I use: # modprobe saa7134 card=41 tuner=17).
> 
> Currently my video works perfect but I get no audio from television.

> I rule out my sound card and the line-in/out settings by plugging my

I also find that i2c_scan=1 added to the modprobe helps, as well as ensuring
you have saa7134-dvb loaded too.  This is for Compro DVB-t300.
