That audio sound

Back in the 1930s manufacturers started incorporating automatic volume control (AVC) in their radios. The reason is fairly self evident. Radio stations varied enormously in strength and users would often be caught unaware when they tuned in a strong station without adjusting the volume control first. The result would be an ear splitting blast of sound. In addition, the volume in radios was sometimes prone to random changes without an apparent cause. AVC masked all of that.

You would think that in the 21st century that this would be just historical trivia and a non issue today. Not so. Although the video is usually close to perfect from all sources, there is a huge indifference when it comes to the level of sound that is fed into your computer or TV. Switching between sources such as FTA or Netflix or YouTube etc invariably means rushing to the volume control to readjust the sound.

I can understand why YouTube could be problematic. Different types of recording devices and varying levels of skill among the people making YouTube recordings unfortunately means that anything goes. It is still annoying when a YouTube is so soft that I can't hear it properly even with the volume turned up full. It is especially annoying when the source is a commercial news site such as Sky News.

What is even more astounding is that when it comes to external audio sources, there is no standard for the output level. Combine that with the fact that there is no standard for the audio sensitivity of the computer or other playback device and the result is often sheer frustration.

I don't understand this indifference to audio. If nobody is going to agree on audio standards then why don't computers have AVC at least?
