There's big file with ext2 with ARM Debian where I can chroot to.

There's functional mplayer (I can `-ao pcm` or `-vo yuv4mpegpipe`) there.

How to record/play sound (or video) from this Debian? Is there things that emulate ALSA/OSS/Whatever to use usual linux programs and android ones side by side? May be there's pulseaudio server for android?
