FIX
I got hold of EA customer support and the second support analyst I spoke to helped me fix it. Thought I'd post it on here as I've only just got the game on DVD (Aug 2018) and had the same issues after trying to install it from disc - my install of Titanfall 1 got to the uncompressing of audio, got to around 36,000 out of 39,000 and failed with the following errors:
Titanfall Audio Installer Error / Titanfall Audio Installation Failed!
Error: A redistributable package (audio_installer.exe) was not installed successfully. Setup cannot continue.
....in relation to the following files on numerous installation attempts...
Client_mp_common.bsp.pak000_005.vpk
Client_mp_common.bsp.pak000_089.vpk
I could not uninstall Titanfall 1 as it hadn't fully installed, so no such option showed.
Here's a fix, as advised by EA (extra steps done by me are in orange).

I just downloaded TitanFall today and was ready to try this game. I kept getting the audio installer error. Your fix was spot on! Thanx dude!!!

Copy the contents of vpk folder and then paste it in x64 folder in bin folder. Then drop cam_list.txt on audio installer, it'll execute automatically.
