     I'm not sure, but I think you might be able to write an .asoundrc which 
could accomplish this using ALSA's OSS emulation.  Take a look at:

http://www.alsa-project.org/alsa-doc/doc-php/asoundrc.php3?company=Generic&card=Generic&chip=Generic&module=Generic

(If the link above doesn't work, go to alsa-project.org, and choose 
"Documentation", and then ".asoundrc".)

Hope this helps,
