Hello,
I
am trying to comprehend QEMU AUDIO backend functionality and need to
implementing device which has few audio channels from which it receives
audio streams (sampled at some specific frequency), and further process
that data stream like mixing two stream.
I am new for the QEMU, Please help me in following queries:
1) Please suggest some document and
example/device implement which has use qemu audio backend.
2) To implement audio
stream read/write functionality, can anyone please suggest pseudocode
for the implementation in which audio stream data (samples at some
specific frequency ) is stored into some device buffers.
3) What steps I need to add into device to setup audio support as per the requirement I mentioned above ?
4) what is the basic working flow of audio backend and accessing audio streams using dma ?
