Hi,
does anyone know if the EM2800 is capable of delivering audio via USB ?
AFAIK, it doesn't have AC97 included.
I recently got some real legacy hardware: a Terratec Cinergy 200 USB
(EM2800 + SAA7113 +TDA9887).
This device has an audio line-in input (also SVIDEO + Composite), but no
extra AC97 IC.
I wonder how this is supposed to work (I actually can't get it working ;) )
Thanks,
Frank

Most of those really old devices don't actually make the PCM audio
available over the USB. That's why they provide an "audio out"
connector - you're supposed to connect it to the line-in on your sound
card.

Yes, I remeber these days ;)
I just wonder why it has a "line-in" input. It seems it is completely
useless...

Just a guess: The line-in is patched through to line-out when the TV
tuner is not in use. That way you do not have to move cables all the
time if you have another device you want to use with line-in on your
soundcard.
