Increasing buffers helps reduce skips by creating a larger buffer space in memory so that the program can keep up with the recording. The trade-off is that there is a bigger lag between when the audio enters your computer and when you hear it playing back, but that doesn't really matter much when you're just digitizing LPs or cassettes.
Yeah, I fully expect it to skip again when I try to digitize "A Love Supreme", with its side-long tracks.
I've purchased an AC adapter for the preamp to see if that helps with any power issues. Basically throwing shit at the wall at this point. stay tuned....
EDIT: Now using the AC adapter. No skips, no hiccups, perfect! Still very low levels of confidence though. I'm going to crank back on the buffers to see if skips come back. If not then that lends some credence to the theory that the USB power in this laptop is shite.
EDIT: Well , runs perfect with buffers reduced, and the Windows device disconnect sound reinstated. It would seem at this point that the root cause is lousy power control through the USB cable to the USB powered preamp causing the pc to think the USB has disconnected. When this did happen I noticed that the level meter for the USB audio codec "microphone" in the windows sound manager still showed input !! Even though there was nothing coming out of the speakers AND SIA was not picking up anything either, apparently thinking that the USB was gone and not checking to see if it had reconnected. Note that by hitting the "NEW" button in the SIA recording window made SIA re-check to see if there was USB audio coming in, and it would start to "hear" it again.
In the end, not SIA, but rather the horribly crappy USB power on this less-than-a-year-old Lenovo T510 Thinkpad. Boy have they gone downhill since IBM.
Anyway, Greg, thanks for your tips and guidance, kept me focused on looking for the real cause.
Now, where's that drink?
