Hi, How you doing XD

I have a fresh installation of Gentoo.
At first everything works well with sound. The Speaker works too. But when I plug in my headphones as usual... the speaker mute and sounds out through headphones. But when I remove the headphones the speaker doesnt work anymore :/

The alsamixer show me that speaker is not mute XD

Is this new hardware or used one? You could have a defect in teh connector there.

anyway check your kernel settings. those hda-intel usually work flawless.

This sounds like a problem with the alsa drivers. You should check that you are using the correct model for the alsa module you are loading.

Try the advice in this link:

Actually, kind of a blind guess, but it sounds like it might be switching to the wrong card after unplugging.
Would you check (for example, with aplay) if the card is still accessible after unplugging ?

Your system speaker is damaged, you have to repair that, otherwise use some external speaker....

I have been suffering a similar issue (not exactly the same).

https://forums.gentoo.org/viewtopic-t-1006168-highlight-.html

For me, the speakers do not work at all. Headphones work ok. But this only happens with kernel >= 3.18. That's why right now I am still using 3.17.7 (any version <= 3.17.7 works fine so I know the speakers are ok).

Also a laptop, and also using intel hda. That's why I think the problems are somehow related.

If you could try 3.17.7 and see if that works, we could confirm whether the root of the problem is the same or not.

I have also opened a bug at the kernel tracker, but given that I am a moron when it comes to ALSA and that currently I don't have much free time I haven't managed to make anything clear out of that thread.

asus k70IJ laptop

weird behaviour

unmute channels, quit alsamixer
channels are muted

again alsamixer, unmute channel, leave alsamixer open
go into google chrome / start a video
channels are muted, unmute again on that opened alsamixer and sound works

alsa is really borked with hda-intel on asusk70ij

it was a bit borked before but now this suddenly going back to mute state is quite annoying.
newest gentoo-sources installed of ~amd64 branch.

as it is only for work this laptop i do not bother but it annoys to see such a mayor feature as mute / unmute broken. and that my channels get automuted without any reason ... considering i use i3wm i suspect any userspace programm at all does the muting ...

alrojas, do you have PulseAudio installed as well as ALSA?

Update: I have found that if I pass "model=acer-aspire" to the snd-hda-intel module, then everything is back to normal (or so it seems, haven't tested thoroughly). At least, my external speakers do work, which is about all I use sound-related in this laptop, along with the headphones output.

So, to me, the problem is that something between 3.17.x and 3.18.0 either broke whatever heuristic the kernel uses to guess the model or changed the default which in my case worked fine.

I am 100% sure I never used that parameter before, I didn't even know about it. And it always worked.
