Greetings all,

I have an old card that I am trying to use for Analog cable. The video quality is good for what it is, but I am getting no audio from it. 

I have tried tvtime, and also getting no audio.

I have installed the snd_bt87x module using the option load_all=1 that is supposed to handle this card, and it installs, but when using the following command: 

cat /proc/asound/cards
There is no reference to to any bttv, only to my intel sound.

I did try looping the sound out of the card via the audio in, and I do get audio(Very scratchy), but was not able to bring this audio in to mythtv. I do get good video.

I haven't figured out how to hook the audio up internally on the motherboard(2007 vintage intel model) as there is no analog connector that matches the old style cd audio connector.

I was hoping to get the sound directly via the snd_bt87x module.

I know there used to be a btaudio module, but from what i gather it is mostly deprecated.

Information from lsmod:
