[CM] snd: xruns with alsa spdif device

[Orm Finnendahl]

Hi,

trying to transfer soundfiles from dat to computer using the optical
spdif input of an alsa supported terratec soundcard I get very
sluggish behaviour of snd and lots of xruns. Using "arecord -D spdif
-f cd <filename>" works fine without reporting any xruns, so I guess
it's not the soundcard.

I set SNDLIB_ALSA_CAPTURE_DEVICE to "spdif" (alsa's name for the spdif
in pcm of the soundcard) before starting snd. Everything works as
expected except for the abundant xruns. Do I miss something?
