First of all there were a variety of cinder tracks, from those made from spent coal cinders with lots of large large cinders that small high schools might have, to better ones made from crushed stone and stone dust. However, there were others made out of discarded WW2 bricks out of England (en-tout-cas track at Rutgers)

, while many of the tracks out in California were made out of clay, I believe. Maybe someone who was from out the can speak to that.
Some of these tracks were loose and by the middle of the meet, lane one was chewed up quite a bit. This was even the case at Penn Relays when many runners would be covered in black, racing in a large relay race and sitting behind the leaders.
The clay tracks in California were quite hard and held up better during competition as long as there were no heavy rains.
Most of these type of tracks were screen dragged, similar to how infields in major league ball parks are dragged and then rolled with a smaller version of an asphalt roller used on roads. If the inside lane became too chewed up during a meet, maintenance people would take the screen and drag it around the track to try and smooth out the inside lanes a bit. This was done mores o at bigger meets than when small dual meets were held.
As to sound, yes, you could hear the sound of other runners next to you and behind you. I suppose it was similar to the sound made when running on pavement with flats. I remember one time thinking someone was right behind me only to discover the sound I was hearing was my paper number on my back flapping in the wind.
I would imagine for the video shots you need of someone running, you could still find a cinder track in existence (there was one at a prep school in Eastern Ct not too long ago). The should would probably have to be tight, as those facilities are quite old and often in disrepair.
