Echo audio interfaces typically don't cope well with bridged PCI slots.
If it's working well for the OP, I'd stick with that exact adapter.
Interesting, Jim, thanks. I'll bear that in mind. For what it's worth, I did a recording session this morning with a decent-sized project (adding some tamborine!) and didn't encounter any glitches at all. Smooth running.
So, as a Heinlein True Witness, I can say that the combination of this PCIe/PCI adapter, plus ECHO Layla 3G, works, at least in my motherboard, in my machine, THIS morning. :-)
If I encounter problems in the future, I'll post an update.
