I'm used to cards like the Hauppauge HVR1110, which exports an ALSA interface for audio capture; the HVR1600 doesn't do this. Instead, it exports a "video" device, /dev/video24 that appears to have some variation on PCM audio on it instead of video. How should I handle this in Xine's input_v4l.c? Should the driver be changed to use ALSA? If not, how do I detect this case, and how should I configure the PCM audio device? If the driver needs modifying, I can do this, but I'll need an explanation of how to do so without breaking things for other people - I've not done much with ALSA drivers or with V4L2 drivers. -- Simon Farnsworth
