Hello, I recently purchased an ASUS Xonar SE sound card and found that the IEC958 output did not work under ALSA. The attached patch to alsa-lib enables the output. I can see that the SE is among several other Xonar models which require special treatment to enable the S/PDIF output, but this one appears to be the only one which puts the digital output on PCM #2.
