Hey all,So i have been noticing issues in the game with audio in Multi-player and Single Player Modes. Its all a shame really since Visceral spend alot of time with the sound design and collecting audio samples for the game. i remember watching "Battlefield Hardline Developer Diary Episode 3 – Sound of Speed" https://www.youtube.com/watch?v=KeSU7JqpmwM [youtube.com]I would like to say i do not know how they do the audio stuff programming wise but there is some issues that i have noticed. Before i go on i have tested the audio by changing the settings in the options for Speaker Type and Speaker ConfigurationSpeaker Type* War Tapes* TV* Hifi* Headphones* Sound BarSpeaker Configuration* Surround* StereoSo i am going to start with single player modeThe starting cutscene audio for episode 3 is very jumpy and there is lots of repeating of phrases like the audio is constantly going in and out of sync. This is the only Cutscene that this happens with for me. After asking friends of mine, some have had out of sync audio in more than 1 cutscene or similar issue as i have.This is an issue on both Surround and Stereo Configuration setting. Some parts of the game when Khai Minh Dao speaks everything is fine through the front channels (Front Left, Front Right, Center) however if Khai Minh Dao is behind me the audio in the rear channels (Rear Left, Rear Right) is really low and can hardly hear what is being said. For stereo if Khai Minh Dao is behind me when speaking there is no audio at all like the game is not downmixing the audio to stereo and instead is cutting off Center, Rear Left, Rear Right and LFEwith the Speaker Configuration set to "Surround" i find the game really lacking on the lower end of the frequency range and find that my sub speaker is getting little to no signal at all through the LFE Channel. this is mostly noticeable from gunfire, explosions and dialogue. with the Speaker Configuration set to "Stereo" things are slightly improved but not great at all.The volume of the vehicles is far too high and drowns out dialog and other environment effects. This is most noticeable where most of the dialogue in moving vehicles outside of Cut scenes is barely audible regardless of the Speaker Configuration setttingsNow for the multiplayer side of thingsSometimes, randomly, there is no audio from the helicopters and have no way of reproducing it. this appears to be random and from what i notice, if it happens with me it happens to others at the same time. I found that out when i mention it to friends when the Heli audio is gone they all mention they cannot hear it too.This one i found by accident and explains why i hear no gunfire when i am killed at times. When the source of gunfire originates from behind you, you sometimes are unable to hear any shots at all. so i decided to jump in an empty (unranked) server with a friend to do some testing. The test was initially to test the difference of audio levels from all directions when i noticed something strange was happening.so i decided to test this strange issue. A friend of mine BoomerangfreakYT was on 1 team and i was on the other. i got him to stand behind me and fire shot in the air when i tell him to. Using the minimap i could see when he fires by when he would show up on the minimap as well as him telling me via Mumble when he fired the shot. i did record this using ShadowPlay but since ShadowPlay only record in stereo also recorded this on a separate PC by recording all 6 channels (Front Left, Front Right, Center, LFE, Rear Left, Rear Right) to seperate mono wav files using an M-Track Eight [m-audio.com]. I then took the ShadowPlay recording and synced the audio.This video shows 20 shots made by BoomerangfreakYT from behind me https://www.youtube.com/watch?v=fI5OqZXl0hw [youtube.com]Now here is what the audio looks like in wave form http://i.imgur.com/TptNKUm.jpg [i.imgur.com]I then done the same test with me facing BoomerangfreakYT at the exact same distance https://www.youtube.com/watch?v=NWcWRNmq1d0 [youtube.com]Now here is what the audio looks like in wave form http://i.imgur.com/DN8IjhP.jpg [i.imgur.com]when you compare the 2 you notice that if the audio source is from the front everything is fine but if the audio is behind you there is a random chance that you may not even hear it as it does not play.to make sure that it was not just me that this was happening to, i got boomerangfreakYT to turn around so i was now behind him and we repeat the test. He had his settings to Headphones/Stereo. He told me when to fire (when i did not show on the minimap and i reported when i fired) he was only able to hear 3 shots out of 20. these tests where done using different weapons and using 3 different Sound Cards and i was only able to hear from 4-8 shots out of 20As stated aboveBasically there are a ton of bugs related to the audio side of things that is not because of my hardware as all tests where done using different soundcards and also BoomeranfreakYT's PC. While the "Sound of Speed" video hypes up how great the audio is, how can us players enjoy the work and effort to produce the "great audio" that gets hyped up about if there is soo many bugs with it.
