My laptop speakers won't work.

[Syncrfo]

Hi guys. I have an ADVENT Roma 2000 and my laptop speakers aren't working! I tried fixing it on my own but I decided to ask you, the experts.
I already tried:
1. sfc scannow (Scan was finished but there is still some errors in cbs.log that cant be repaired. And oh, is it normal for the scan to end at 98%)
2. enabling and disabling realtek in dev manager.(uninstall+restart is included)
> Like to add that in its properties it's saying, "the device is working properly"
3. downloading and installing the new update of realtek.
4. Putting external audio devices.(like headphones, earphones, etc.)
> Still I can't hear a sound from these.

I don't know but I think the pop-up message after I start my laptop, has something to do with it.

iaanotif.exe - system error
isdi.dll is missing

Sounds like your sound card has blown. Do you hear any system sounds at all and when did this problem start occurring?

The files missing are to do with RAID.

The error occurred just yesterday. Every time I start it, i hear a sound. Just like a tap.

In regards to the sound... Is it a bit like the sound when you plug the audio jack into speakers sort of sound?
