How do I get my sounds working?

I purchased an Asus Vivobook Pro K6500ZH PC a few days ago and I installed Ubuntu on it, Everything works fine beside my sounds, for some reason I can't hear any sound.

I've tried many things which didn't work like playing with alsamixer and so on. I only found one solution that works for me on youtube which uses the following script:

#!/bin/bash
sudo hda-verb /dev/snd/hwC0D0 0x20 0x500 0x1b
sudo hda-verb /dev/snd/hwC0D0 0x20 0x477 0x4a4b
sudo hda-verb /dev/snd/hwC0D0 0x20 0x500 0xf
sudo hda-verb /dev/snd/hwC0D0 0x20 0x477 0x74

Everything seems good until I reboot my PC and I need to run the script over again in order to make the sounds work, it's very annoying.

What can be the reason that I cannot hear any sounds and how can I fix it without running that script whenever I reboot my PC?

I have a soundcard: HDA Intel PCH
Chip: Realtek ALC294

Output of the: sudo lshw -c sound command
