So I installed linux Mint 15 "Olivia" 64 bit on my Mecer W550EU laptop

I have HD Audio with a VIA chipset

soundcore              12680  1 snd

And my sound card

charles-W55xEU charles # aplay -l
**** List of PLAYBACK Hardware Devices ****

and my audio device

charles-W55xEU charles # lspci -v | grep -A7 -i "audio"

Sometimes when I boot up, soundworks, other times it doenst, it is completely random, so far, no-one on xchat linux help or linux mint forums was able to help me, I have always had issues with sound on VIA chipsets

I have:

sudo apt-get upgrade && apt-get install mint-meta-cinnamon

it seemed to help but after 2-3 reboots, the problem came back,

btw, everytime I checked, pulse audio is selected to

Duplex Audio Input & Output

and alsa mixer is always unmuted!

I am not sure if you have found a fix but I found a temporary fix so that sound works on your VT1802 card

have a look, post #2 - #4 for indepth details

in short:

  • add or modify your alsa-base.conf file(the last line) to look like this
  • options snd-hda-intel model=auto indep_hp = true
  • reboot
  • sleep the system
  • wake it up again
  • login, sound works (hopefully)

I hope this works for you guys, been looking for a fix for this for a couple of years...
