[SOLVED]No sound with ALSA. I'm looking for help with troubleshooting.

Hi!

Recently I bought a new laptop (HP Probook 450 G1). For some reason I can't hear sound from the laptop's speaker or headphones. I already read the troubleshooting guide on wiki. Unfortunately none of the solutions described on the wiki helped. I'm not using PulseAudio and I'm out of ideas.
Additional information:

Alsamixer screenshot.

Re: [SOLVED]No sound with ALSA. I'm looking for help with troubleshooting.

Try in /etc/modprobe.d/whateveryouwanttocallthisbutmakesureitendsindotconf.conf:

(edited to keep emeres happy)
To switch order, making what was "card" 1 the default:

options snd-hda-intel index=1,0

or to just disable what was "card" 0:

options snd-hda-intel enable=0,1

I also have, in that same line, to fix kernel warnings about bdl_pos_adj:

bdl_pos_adj=64,64

Then reload the sound modules

Yep, that did the trick. Thank you. I had to change my default soundcard from 1 to 0 in /usr/share/alsa/alsa.conf.

@brebs Why disable a card? It should work as expected.

That file will be updated/overwritten with alsa-lib package, use the defaults node or other custom configuration in /etc/asound.conf or ~/.asoundrc instead, should you insist to use the alsa-only approach. The index parameter sets the order of sound cards according to position on the bus and can be used to set the default card.

Should you consider this issue solved, then please mark the thread as such.

Why disable a card?

So that the right output becomes the all-important *default* output. And it's conveniently a simple one-liner.

 I am very aware of that, why not use index instead? It is as convenient as enable. Why leave the user with a disabled device, when it can continue to work? I consider this highly inefficient, because it does not solve the actual issue and creates a potential problem in the future.

 In this case, user interaction was the cause, so it does not matter.

Edit: Typo.
