[alsa-devel] Individual PCM stream control

[Nagalla, Hari]

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
