[alsa-devel] Individual PCM stream control

Hello,

I am new to ALSA, so some help from experienced folks would help..

We are trying to develop ALSA support for our DSP based mixer. In our architecture DSP performs the mixing, sample rate conversion etc. My question is how, can does the user space applications exercise controlling individual PCM stream to the mixer? Ex: individual stream gain control, individual stream mute, etc.. Any user space example code would be useful too..

Thanks

Hari
