Default ALSA for audio

Hence I'm currently trying to decide if his working on having EZCap output
audio (without some further processing on the computer) is chasing a
boojum. So not an 'alsa' problem at all. But I dunno as I know zero about
the EZCap. My experience is only with the 290e and FUNcube.


I have the Easycap dongle and a couple of USB tuner sticks and they are
very different devices. The Easycap (or EZCap) is basically a digitizer
which samples an analogue composite video or S-video input, with audio,
and sends PCM data to the USB. I don't know to what extent that data is
compressed, but I do know that it requires a fast USB connection and a
fast processor otherwise it simply won't work.

EZcap can be used with VLC if a driver is installed, but this is as a
video capture device and not as a tuner device such as the Hauppauge,
which supplies an MPEG2 or H.264 transport stream.
