no sound on LM16, driver VT1802 HDA intel

[charles]

Hi

I see many people have isues with this sound card

I have had many previous instalations of linux, e.g. Backtrack, Kali, Ubuntu, Linux MInt 13-16, all gave EXACTLY the same issue, 2-3 reboots after fresh install, then no sound afterwards, I would play around, search for fixes then every once in e.g. 5 reboots sound would work once, I have searched for fixes for almost 6 - 12 months for a fix (on and off), no luck

i have seen the post

although I do not understand what I need to do

could you please elaborate

good day

I am proud to say, this works for me, all musst give it a try, however I cant guarentee it will work

only change is in the alsa config file in

/etc/modprobe.d/alsa-base.conf
right at the bottom under the # Keep snd-usb-audio line I change the line
    options snd-hda-intel model=auto indep_hp = true

I am not sure if this is the reason which causes it to work but maybe it just works for me

---------------------------------------
BUT VERY IMPORTANT:
---------------------------------------

add the line I mentioned above, THEN reboot,
after rebooting you might get sound, u might no, it depends (as I understand, go to terminal, type "alsamixer", then it should bring up a kind of volume settings in the terminal, press F2 >pcm: it shows, in my case 3 listed cards,

00-00: VT1802 Analog : VT1802 Analog : playback 1 : capture 1│ →
│ │ │00-02: VT1802 Alt Analog : VT1802 Alt Analog : playback 1 │ →
│ │ │00-03: HDMI 0 : HDMI 0 : playback 1

I am led to believe that in the alsa-base.conf, Linux assigns an index to each card, and sometimes the vt1802 card is assigned to the right index, thus it works, so random sound operation after reboots are not quite so random after all)

So after rebooting, w/o sound (if your sound works, good but just read on, for future reference), put your laptop on sleep, wait for it to "shutdown", wake it up again and your sound should work, I cant guarentee it will work, I have been searching for almost 2 years for a fix, since I have always had problems with sound in linux from this sound card

hope the devs cant find a way to patch this up

so just to recap in instruction form

1. get your system to latest mods with: terminal > apt-get update && apt-get upgrade -y (leave terminal open when finished)

2. type> cd /etc/modprobe.d/

2.1 open alsa-base with your favourite text editor, i use nano: terminal > nano alsa-base.conf

[charles (cybergurken)]

follow up on previous post #3

2.2 navigate to the bottom of alsa-base file (look for "# Keep snd-usb-audio from beeing loaded as first soundcard
")

add this line to the end (if it is already there, make sure that your model=auto and indep_hp=true)

add this line: options snd-hda-intel model=auto indep_hp = true

3. reboot your system

4. boot up and login

5. put your system into sleep and wait for it to turn off

6. wake up your system, and boom!!! sound should be working (if not, im sorry to hear that, hang in there, hope devs will patch it up soon)
