No idea why you're being downvoted... I also think that would be one of the most obvious areas where Google could eventually put Fuchsia to use - it would have several advantages: a new OS with a more modern architecture (getting rid of the GPL-licensed Linux kernel, which Google probably sees as an advantage); the possibility to update the kernel independently of the drivers; getting rid of Java and its legal liabilities which Oracle could exploit in the future etc.
Do people actually have audio problems with android? People don't seem to even have a problem with all the bad quality audio devices they ought to have a problem with let alone the OS.
Musics do have, hence why Samsung had their own real time audio stack, which Google eventually adapted into Android.
There are several years of Google IO stuff going into this, until you finally reach the talk done together with a Samsung representative and a couple of DJs using the new demo app on stage to prove Android was finally ready for music professionals.
It is just a matter to go down the Google IO archive.
