does anyone know about pulseaudio? how to install the package of libasound2-dev, libspeexdsp-dev?

[jongrock chun]

I'm developing the audio system that tele-communication between server and client device over an internet.

I had a problem that is echo(howling).
so I'll fix the problem with installing the libasound2-dev and libspeexdsp-dev.
but I didn't find that.(opkg install libasound2-dev libspeexdsp-dev)

anyone know the way of installing above package?
(I used the omega2 as client device.(version : 4.4.74, 0.2.2 b201, using a alsa package))

thanks.

I installed the libspeex, not libspeexdsp.
but opkg do not have a libasound2.

and pulseaudio daemon didn't start.
has anyone succeeded in executing the pulseaudio?
Or anyone has the reference information about pulseaudio in omega2?

thanks.
