Why in the world would you try to play 8000- Hz Mono? It will sound awfull. Also it may be that your card cannot do mono. (that is what the error message seems to say) Get a proper .wav file and test with that.

What are you trying to play?
OK i ripped a proper wav from a CD.
$ aplay -D hw:0,4 track_01.wav
Playing WAVE 'track_01.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
Warning: rate is not accurate (requested = 44100Hz, got = 48000Hz)
please, try the plug plugin (-Dplug:hw:0,4)
aplay: pcm_write:1083: write error: Input/output error
$ aplay -Dplughw:0,4 track_01.wav
Playing WAVE 'track_01.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
but my DAC reports that there is no signal being sent.
$ aplay -D plug:spdif track_01.wav
plays, but sounds awful... very tinny, distorted, brittle, I've tried this DAC with my old CDP as the transport and I know the DAC can sound a hell of a lot better than this.
$ xmms track_01.wav Message: fmt 5, channels: 2
The player just 'hangs' in the play mode until i configure the alsa plugin to output to hw:0,0....
Also, is there a way to get the device to not upsample the spdif output to 48khz? hmmm I'm getting ahead of myself here...
cat ac97#0-0 ... SPDIF Control : Consumer PCM Category=0x2 Generation=1 Rate=48kHz
And if anyone knows of an affordable firewire, usb, or cardbus device that can give me 44.1khz spdif output with ALSA i'll drop this thread and buy that instead.
Thanks again for any advice! I can post my .asoundrc or my asound.state if it would be any help.
