Within the C:\Documents\Battlefield 3\Settings\PROF_SAVE_profile .txt document that everyone should have, there is an option at the very top called GstAudio.AudioQuality. This is, as I have found, an independent variable outside of the normal HI-FI, War Tapes, Headphones, etc options that are available to us. It was defaulted to 0, and I changed this to 4. Instantly, all my sound glitches are COMPLETELY gone, and I am enjoying this game immensely now.
