Response to myself: No.

Here's the reason found in hda_codec.c:

/*
 * set up the i/o for analog out
 * when the digital out is available, copy the front out to digital out, too.
 */
int snd_hda_multi_out_analog_prepare(struct hda_codec *codec, struct hda_multi_out *mout,
				     unsigned int stream_tag,
				     unsigned int format,
				     struct snd_pcm_substream *substream)



I'll document this behavior in the wiki once this one is back online.

I'm not so sure this copy is a good idea though. It may be more clear
and helpfull to provide a switch in alsamixer.

Cheers
