     I am using the sigma for sharc.But I found it something strange with the AGC module.I linked the channel left as followed:input->volume control module->AGC module->output,while the channel right as followed:input->volume control module->output.After that ,the project was  sucessfully downloaded into the EZ-board and nothing wrong was shown.However ,I could't control the left channel with neither  the volume control module nor the AGC module.Something strange is that when I changed the right channel's volume control module,the left channel 's volume would be changed as well.Can you tell me why?And the usage of AGC module?
