Dear Folks I don't expect many of us will have any reason to upgrade the sound card on this puppy, but I thought y'all would know whether it was possible, and if so, within what limits. Trying to layer recordings with the standard sound card results in a seemingly inevitable latency - so you make a recording, and then record over that, and the second track has a half-second delay. This is widely attributed to cheap sound cards; this explanation is further reinforced by the fact that I have another rather old machine that has a fancy sound card, and never have this problem on it. There may be software solutions, I'm not sure. But I thought if anyone knows the viability of a hardware solution, it's you folks. Thanks for your consideration, your presence, and this great forum.
