absolutely! sorry i wasnt clear enuf.

here is the next phase of the problem that i need to solve:

i am working on a space constrained embedded system. it will always have the same:

 hardware (via8237rplus with a via vt1618 codec)

 software (the audio player application that i maintain)

 content format (the music get's encoded by my music programmer coworkers to a fixed format)

since i dont need a generic solution, it would be very helpful to me to not use alsa-lib and just use the alsa modules the way that our current version of the player uses /dev/dsp from the alsa oss-compat kernel modules.

i'd like to open and playback to /dev/snd/pcmC0D0p and /dev/snd/pcmC0D1p directly if it's a reasonable thing to do.

tnx!
