How can you determine which wire is hot or common when all the wires in the wall are black?
If it is in a house generally black wires are hot and white wires are neutral (common). The neutral and ground wires are tied together in the main panel.
With that said if you put 1 lead of your meter (set on AC voltage) on a black wire and the other lead to ground and you get 120 vac that wire is hot. If you get no reading it could be classified as common.
This is the normal wiring practice.
This is a basic assumption without having 1st hand knowledge of the wiring system
If in doubt contact a qualified electrician

To safely and effectively run speaker wires in a wall for a clean and professional installation, follow these steps: Plan the route: Determine the path the wires will take from the audio source to the speakers, avoiding any electrical wiring or obstacles. Use wall plates: Install wall plates with built-in terminals to securely connect the wires and provide a clean finish. Use in-wall rated wires: Use speaker wires that are rated for in-wall installation to meet safety standards and prevent interference. Use a fish tape: Use a fish tape to guide the wires through the wall cavity without damaging the walls or insulation. Secure the wires: Use cable staples or clips to secure the wires along the wall studs to prevent them from sagging or getting damaged. Test the connections: Before closing up the wall, test the connections to ensure the speakers are working properly.

In sheep the allele for white wall parentheses A is dominant over the allele for black wall parentheses a how do you determine the genotype of a white ram or male sheep?
To determine the genotype of a white ram, breed him with black females. Black females are homozygous recesive for the black trait, a. If the ram is homozygous dominant, all offspring will be white (and heterozygous). If the ram is heterozygous, approximately half of it's offspring will be white and half will be black.

Then, use the fish tape or wire snake to navigate the wires through the wall, making sure to secure the wires to the tool before pulling them through. Be cautious of any obstacles or electrical components within the wall to avoid damage.
