It is actually more like a hoax. To wit: I have a builtin sound card into my laptop without any spdif/iec958 folderol. Now I plug in an IEC958 adapter into USB (which counts as a soundcard of its own). What happens now if I do aplay -D spdif something.wav ? Most certainly not the soundcard with the S/PDIF output gets used. Instead some nonsense happens. I have found no way whatsoever to get this card to output anything except by using Ubuntu's Sound preference setting to make the ridiculous S/PDIF only sound gadget the default sound device. Only then will I ever get aplay (which in contrast to alsamixer does not have something like a -c 1 option to specify card 1) to use the SPDIF gadget. But I don't want to use the gadget for all of my output. And I have been unable to find any man page or info or web page accessible by Google that would tell me how to do this. It is rather silly. -- David Kastrup, Kriemhildstr. 15, 44793 Bochum
