how to mute speaker when headphone is plugged in (on kubuntu)

sunnior · 04-04-2008, 10:02 AM

My headphone never mutes my speaker. I have tried my best to solve it, but failed. This problem has become my headache.

I use kubuntu 7.10. I tried to use kmix to turn off my speaker, but in my kmix there is only two selections : input and output. And in the output, I can only control master, pcm, capture, much different from what was showed in the handbook.

the bottom showed HDA NVidia. I also try alsamixer, but that didn't make any sense.

I also tried to search an answer from the internet. It seemed few people solved it. And the way was too complicated for me to understand.
I really really need your help!

some information I thought might be useful:

00:07.0 Audio device: nVidia Corporation MCP67 High Definition Audio (rev a1)

│ Card: HDA NVidia │
│ Chip: Conexant ID 5051

Hi sunnior, Welcome to lq. Is this a laptop, if so, what make/model?
Good luck. ;-)

Yes, it's a laptop. I use HP presario V3700 with AMD Turion 64X2 TL-58.

On most electronics, portable radios and the like, the speaker mute is actually performed by a set of switch contacts in the headphone jack. I'm not aware that a laptop would be any different. Are you sure that the jack is not defective. Have you tried booting another OS to see if the mute works correctly with something other than Ubuntu?

What is the output from the following?

Code:

# aplay -l

Good luck. ;-)

By typing aplay -l I got:

Just now, I have tried on fedora 8 for 64-bits(It really took me some time), but I didn't see any difference.I'm sure the jack works well in this new laptop.

After all, thank you for this good suggestion.

That didn't give me what I was looking for. Try this please.

Code:

cat /proc/asound/card0/codec\#*

Good luck. ;-)

Wish it will be helpful, though I can't understand at all.

Try adding one or the other of the following lines to your /etc/modprobe.d/alsa-base.

Code:

options snd-hda-intel model=laptop
options snd-hda-intel model=laptop-hp

Good luck. ;-)

sunnior · 04-09-2008, 05:34 AM

I tried both, added one each time to the end of the file /etc/modprobe.d/alsa-base, and then reboot. But it didn't work, strange thing....

This is a segment of the code:

I'm on Fedora 8 / x86-64 on an ASUS laptop, GNOME desktop, and what I find is that I have to enable the headphones on the Switches tab of the Volume Control applet, then mute the speakers. Voila - sound through headphone connection but not speakers.

Peacedog · 04-09-2008, 07:04 AM

Once you've got the module options in place you may have to adjust some things in your mixer also with proper module options you should have more channels available and recognized by your mixer. There is a thread here that may help.
Good luck. ;-)

sunnior · 04-10-2008, 04:40 AM

Well, I must say I couldn't solve this problem now. I'll go and learn more, and then come back to have a try. I think this problem won't constitute solved to me unless I understand why is in this way.

Thank you "peacedog", sincerely.

Peacedog · 04-10-2008, 07:29 AM

Did the module options give you more channels in your mixer? If so, look for Jack sense, or Headphone Jack sense.
Good luck. ;-)
