Yes. Please also note that the sum is the number of channels in that program. There can be up to 16 independent program_config_elements in one frame. And program_config_elements must come before all other syntactic elements in a raw_data_block.
Thanks,

Hi,
Thanks for the response.
Please note that I am not looking for the channel to speaker mapping, but only the number of channel in the audio.
Just to confirm whether I have understood it correctly, do I have to add up the values of the following parameters mentioned in
program_config_element function?
num_front_channel_elements
num_side_channel_elements
num_back_channel_elements
num_lfe_channel_elements
num_assoc_data_elements
num_valid_cc_elements
Regards,
Angshuman
