Re: Distorted and crackling sounds
Please check sound using external speaker.
if the result is same as using internal speaker, it's mean your mainboard may have problem, but try to install sound driver first.
if the result is different, you may have some loose screews inside your laptop and it stuck on internal speaker.
if you still have warranty, send it to acer.

If the sound is distorted on all sources over both speakers then the speaker amp on motherboard is suspect. To eliminate bad laptop speaker possibility, try hooking up another audio source to the audio output of the laptop and hear what happens. If they also sound bad then the mo bo is definitely the culprit.
Because I do not know your particular computer in detail, I will answer generically.
Because of the complexity of design where the interaction between software drivers and the hardware are very inter-dependent, it is difficult to determine the fault directly. I would suggest to uninstall the sound card drivers using the device properties manager, re-start the computer, and let it re-install them. If they do not auto install, then do it manually using the respective installation source location.
You can also try downloading the sound drivers directly from the Acer site and re-installing them, or from the respective sound card (chipset) manufacture to see if this fixes the fault.
I am assuming you tried listing to the sound using several headsets or external speakers to test it. I know of cases where a person was complaining about distorted sound from their computer. It turned out to be the speakers were defective and not the computer.
Hello sir/mam, as i analyze you problem, there are several points that may cause these problem, 1. your hard drive might have bad sectors that at a point the heads of the hard drive have difficulties reading the information thus cuasing the sound and lag of screen to become distorted. so i suggest you regularly scan for bad sectors. 2. its a long shot, it may be your software, you have to reinstall the porgram where you saw the lag. if every thing else fails, if its not a hassle, reinstall your OS and work with a fresh copy of programs on your laptop. if you have anymore questions, let me know. thanks
Yes in a laptop Sound Card is comes as a integrated part of System. Before doing anything else it is highly recommended that you must download the Sound Driver from the Acer website and then install it on your Laptop. Be careful download the only sound Driver that related to your laptop model by using your laptop serial no.
your memory is low on resources need to increase memory.everything on ur pc uses mem.audio and video devices use an aweful lot.if you have open another program not only will ur audio be distorted but ur other program will be running slow.

hi, first check the speakers if they r bad, u can do this by connecting external headphones, if it still sounds the same, then the probs is with ur sound card, uninstall it and install it back, let me know
