Yes. 32 bit.

My gentoo /etc/make.conf contains
CHOST="i686-pc-linux-gnu"
CFLAGS="-march=i686 -mmmx -msse -msse2 -O2 -pipe -fomit-frame-pointer"

Yay!

Sorry.
alsactl -f /etc/asound.state store
asound.state file attached.

I re-pulled alsa-lib, and now:
arecord -D plug:spdif -d 10 -f dat -t wav |aplay
And
arecord -D cards.pcm.iec958 -d 10 -f dat -t wav |aplay
In both cases, I hear nothing, and they end with the same output:
Recording WAVE 'stdin' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo
Playing WAVE 'stdin' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo
arecord: pcm_read:1324: read error: Input/output error
I re-pulled alsa-lib, built successfully, and retry record, with same error:
rm -rf alsa-lib
hg clone http://hg.alsa-project.org/alsa-lib alsa-lib
pushd alsa-lib
./hgcompile && make install
popd
arecord -D plug:spdif -d 10 -f dat -t wav |aplay
At this point, should I pull from your daily builds?
I retried arecord with verbose mode on:
arecord -v -D plug:spdif -d 10 -f dat -t wav |aplay
