I’ve been in similar situations while renting. I ran ethernet cables along skirting boards and around doorframes and hid them inside adhesive cable raceways.

Ok this is an idiot question but how does the global average temperature change so much over the course of a year. Is the northern hemisphere warmer overall during its summer compared to the southern hemisphere in its summer?

Go to a chemist and get some pseudoephedrine. That stuff is magic for blocked noses.

Is this for movies and tv shows? I fix it at the output level and leave my rips unchanged. Check your TV or AVR for a “night mode” or “dialogue enhancement” or use the “reduce loud sounds” system setting if you’re playing back an AppleTV.

If the issue is specifically quiet dialogue and loud action scenes, get a dedicated center channel and boost its volume by a few dB.
