asus n550jv audio problem: no sound from notebook' speakers

Question

Ubuntu 13.10.

The problem is: the internal speakers don't work. I have no problem when I'm using the headphones. There is no hardware issue since in windows 8 everything works perfectly(external subwoofer included).

I tried to modify /etc/modprobe.d/alsa-base.conf but I can't find the correct model to put into:

 options snd-hda-intel model=

The file HD-Audio-Models.txt doesn't contain the model for ALC668. Then I found out that this method may not be so useful because the information in https://help.ubuntu.com/community/HdaIntelSoundHowto is outdated.

I also played with alsamixer -V all command but I had no success.

Some info:

Thank for you time. The problem is: the internal speakers don't work. I have no problem when I'm using the headphones. There is no hardware issue since in windows 8 all work perfectly(external subwoofer included). — artBCode, Nov 2, 2013 at 21:46
Have you check that the volumes are not muted? What amixer -c 0, pacmd dump-volumes says? Edit your question and add the previous comment too plus the output of those commands? — Braiam, Nov 2, 2013 at 21:50
You sure the information of amixer -c 0 isn't cut off? Try adding amixer -c 1 too. — Braiam, Nov 2, 2013 at 22:14

I've got the same laptop Asus N550JV and faced the same issue as yours.

While booting, I chose 3.11.0.12-generic kernel from the "advanced options for Ubuntu" and sound started to work just fine.

I rebooted and used the newer standard kernel and now it's surprisingly working.

Try that.. hope it will help .

In addition, i have noticed that sound doesn't work if you boot into ubuntu after windows 8. So you have to reboot again and sound appears.

A note on what Yauhen said: I found that if rebooting from windows and the sound stopped, I could just suspend and resume to make it work again (full reboot not necessary). Also see bugzilla.kernel.org/show_bug.cgi?id=67711

I can confirm everything of the above. Maybe we need the 3.12 kernel branch, in the end.

Same happened to me. Sound only worked with an updated kernel (3.11.0.12). I just waited for the official Ubuntu update. However, after upgrading it again to 3.11.0.14 or .15, speakers stopped working. After doing what Bassam suggests, I got my speakers sound back.

For those of you trying to enable the subwoofer output, I recommend you to follow these guides:

Ubuntu-es - External subwoofer in Asus N550JV - Chip ALC668 (in Spanish)
Keep hungry - ASUS N's subwoofer in Ubuntu 13.10 (in Spanish too)

They worked fine for me.

I've got the same laptop, and same problem. I installed the new kernel 3.12 and now my speakers are working. Im running xubuntu 13.10.

The following link gives and explanation on how to upgrade kernel, and a warning that this may cause other problems:

"We have to warn you from the get-go. Canonical does not recommend updating your Linux kernel to other versions than the ones provided on official channels. This is not a totally safe procedure and you might have problems afterwards, even system failures. On the other hand, you might get better performance from your system."

I've tried this solution on asus n750jv (the same soundcard). The sound appeared but: 1)External subwoofer doesn't work. 2)The only working configuration is 2.0 3)In skype: if i set in system setting analog output as default i have sound, but microfon doesn't work. If i set analog input as default audio profile, microfon works, but there is no sound from speakers.

When I upgrade to the 3.12 kernel, I get a kernel panic: not syncing, no init error on boot. Had to boot to the older kernel to get back.
