Hi there,
I have a WinTV Go and a TwinHan VisionPlus DVB card. I would like to be able to
capture the audio from the WinTV board. I have loaded snd-bt87x and it would
appear that it has found the WinTV audio, but no ALSA devices are created. Can
anybody provide information on how to get the audio output working for this
card? Some relevant information is below:
