Camera /character width

The door width is significantly wide (about 4 times wider than the character and about twice the height); however the character/camera won't pass through.

Also, is there any way to associate sound with the physics. I have a beer can falling off a desk, but it makes no sound. Is there a way to have it make a sound when it impacts the floor?

    
    var m_ctl = require("controls");
    var m_scs = require("scenes");
    var m_sfx = require("sfx");

    var speaker = m_scs.get_object_by_name("YOUR_SPEAKER_OBJECT_NAME");
    var beer_can = m_scs.get_object_by_name("YOUR_BEER_CAN_OBJECT_NAME");
    var sensor = m_ctl.create_collision_sensor(beer_can, "YOUR_MATERIAL_COLLISION_ID", false);  

    var callback = function(obj, id, pulse, param) {
        m_sfx.play_def(param);
    }
    m_ctl.create_sensor_manifold(null, "SOME_UNIQUE_ID", m_ctl.CT_SHOT,
            [sensor], null, callback, speaker);

With regards to the door opening issue, it made sure the material was set to Special: Collision but the problem persisted. I did some testing by moving the room forward and left the door behind and I was able to go through the opening. It seems that once the door moves, it seems to leave behind a 'ghost' of itself which continues to block the opening. I have attached the blend file.

Regarding the beer can dropping, I have placed the code in the .js file and ensured the objects were named appropriately. I left the sensor manifold ID as "SOME_UNIQUE_ID", assuming that it was not important what it was called. )

However, I still did not hear any sound when the can falls. I noticed that the var_sensor is set to 'false', is this correct? (The beer can is the one that rolls off the right side of the table when the scene opens)
