>>Have you considered using PulseAudio for this?
Mark thanks for the suggestion and i checked out PulseAudio for my requirements.I found out that i don't need all the things in PulseAudio
a. I just need good resampling code.Can i just use just the resampler code of pulseaudio(mine is mobile enviroment)?
b. Just want a good mixer at ALSA-LIB level.As of now this is provided by android framework but i want this to be done by ALSA-LIB so that i
can replace with some good mixer later on(if i find that some other mixer is good).DMIX is providing that but it's not that good.
c.Jaroslav suggested to use sox resamplers but for that to work i have to get the sox resampler code(proper license) and need to build it for my system and link it
with corresponding functions of ALSA-LIB so that they can call relevant functions for resampling.As i am working on mobile domain i think i need to do the
integration of sox resampler code with ALSA-LIB for that to work??
or
Can i just use the integrated sox library(some .so i guess) and change the asound.conf for using that library??Will this work??
d. I saw some check-ins related to Scenario Manager.As of now scenario manager functionality is also given in Android(we open a differnet
device and the corresponding hooks for changing the routes dynamically) but i think if it given in alsa-lib switching will be much faster and this
will increase the system performance.
