Question [Q]android x86 problems

I know theres lots of guides and questiond asking the same exact thing but none of them worked, i tried asking stackoverflow but no one answered but anyways i aam currently running android x86 4.4 on my internal hard drive and the sound doesnt work, if i put in a live cd the sound works just fine but when i switch back to android the sound no longer works the headphones also dont make anysound but thats for any operating system and if it does make a sound its only through the left headphone and last thing is that it keeps sying low memory with over 35 mb and i know there should be A LOT more than that so is there anyway to add more space without a flashdrive or sd card inserted all the rime, i can use my whole hard drive because android x86 is the only os i have on it
