Hi, My project needs ALSA device driver integration. Can you please help in in getting:1. Demo application(may be sound recorder and player) using ALSA device driver.
2. in knowing function call traces about packets coming from sound card and being delivering to demo(during recording).3. in knowing function call traces about packets going from application to ALSA till sound card (during playing sound).
I just want to understand the function/call flow from/to application to/from sound card.
My project have requirement to change the packet flow and add some code and test in the packet flow path like delay the sound packet, modify the sound packet from app till sound card and vice versa.
Please kindly provide some pointers.
Thanks-Nagendra
