yes, "Echo Indigo IOx" soundcard seems to be supported by ALSA. I have
always wondered how important is driver support in terms of sound
quality? I mean the digital-to-analog converter should determine the
sound quality and as this is done in hardware, drivers should not
matter (very) much, should they?

thanks! I mailed my question to Linux Audio Users mailinglist as well.

I agree that USB if more future-proof and ubiquitous compared to
ExpressCard. On the other hand, for example current models of both
Lenovo T series and HP ProBook/EliteBook series support ExpressCard.
As and expansion slot, ExpressCard is currently the standard.
