Never had tis problem before, but it started couple days ago randomly... Sound echoes and have like 1-3 sec of freeze which sucks terribly. I unstalled the game complete and install again, problem still persist. I went on and update my audio card driver and even complete reformatted my laptop which seems to fix the problem initially. Right after launcher update, problem comes back again but this time no freezes, so annoying and crappy echoing thru out the game. Example: Doooouuuubbbbble DDDooooouuuubbbbbble Killllllllllllllllllllllllllllllllllllllllllllllll !
No freezes/lag accompany with it after reformatting comp. Oddy, i copy the whole LOL files to another comp and no echoing in that comp. Plays any video and sound without any problem. Just hving issue with LOL sounds.
edit: I don't think the files are corrupted, i had songs playing in the background while running LOL. Results: LOL sound echoes and lags little randomly but song does not echoes or anything. It is normal, so sound card is fine. Then i went and swap the video card, i hv 2 video cards, 1 is integrated intel HD and other is nvida gt525. After swap to integrated graphic, lag and sound echoing seems to be gone. Could be the gt525 is acting up or some ****.( had latest drivers installed for it)
NOTE: I had never experience any lag or sound echoing with gt525 until reccently, about 3 days ago.. Wondering could it be that the gt525 hardware is failing? Laptop is only about a year old
edit2: tried playing other games with gt525, works fine and no sound echoing in other games. So my nvdia card is fine. Must be something within the coding of LOL that don't work well with some graphic cards? Now im playing LOL with intel HD only and no lag, no sound echoes. But i really want to use my nvida card cuz i can see graphics sometimes slows down with intel HD, but not game breaking.
edit3: LOL, since the update on 2/16/2013 with the 6mb file through launcher, my intel HD graphic now has the same echoing sound/lag effect as my gt525m. ROFL,, riot are you joking me?? Now im screw all over again, ......... PLZ look into tis issue..!!
