- ASRC tinymix command is split into two. One for configuring and another for starting.
- assign correct asrc instance ID and asrc configs.
- Update correct asrc configs in get function to retrieve values each time.
- Handle multiple parameters from tinymix command by storing the values in global variable and enable asrc once all params are received.
- Fix port type assignment for ASRC.
