Thank you so much. I had read through both the "asoundrc" document on
the alsa site, as well as the "plugin interface" description in the
developers documentation, but couldn't figure this out.

With the cascade idea, I even managed now to also add a "rate" plugin
into the cascade to convert to 48 khz (else there was distortion).. and
everything works perfectly now (well, as far as my need to have bmp
running in the back while playing games with sound is concerned).

Oh, btw, since I'm already here, something I was always wondering.. why
did I need to write this fairly complicated .asoundrc to get things
working? I mean, having sound in multiple applications, volume control,
and no distortion, is what I'd expect to get without any extra
tweaking..
