Subject: [mythtv-users] Audio from SAA7134
> 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
> steps I have to go through to get it in the audio device list. The
> 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
> speakers direcly into the line-out of the tuner. I used to do that on
> my last card and it would have sound, just the preproccessed sound so
> it's 2 seconds lagged.
> >From reading Wiki's it seems this card is generally plug and play. But
> I can't get it to work. I'm fairly good at Linux for server
> configurations but not much for desktop things such as audio/video.
> So I don't know where to start for troubleshooting.
> These are some outputs from commands:
> # arecord -l

> I use:
> modprobe saa7134 card=41 tuner=17

> I'm currently using the newest version of KnoppMyth and MythTV. But I

> Any help troubleshooting this would be greatly appreciated.
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.
