a216 i believe,,, ummm its super low end i got it on my 17th bday, its computer pos been dropped down stairs and stepped on but before any physical damage was done sound stopped working,, ummm i believe between me my step dad and my ex roomate have basically done everything u can, that i believe, and i honestly had no idea u can get a expansion sound card or device for a laptop? also mic would not work im not sure if they both go thru sound card it would make sense if they do but thats input not output honestly i was hoping this was diagnosable and fixable without funds since like i said its been stepped on and dropped down cement stairs screens all cracked, pieces missing lol something is wrong with a di-od idk how to spell it, when computer gets warm if u tilt it, it powers off, according to my uncle its that word of whats causing it lol ummm processor is shot or something huge latency and loud processor sounds occasionally while doing easy tasks, it does have heating problems like mentioned in someones reply, extreme heat but dont really matter in my opinion as long as vents are blocked,,
i think i got off topic,, replacing the on board with a stand alone its not worth money in my opinion i will have a new primary computer in like3 months this computer is worthless to me so unless a card cost like 10 bucks imma just live with sound being messes, but if i can fix it with an insomnia filled night for free im completely down
