[SOLVED] new laptop. Headphones doesnt mute internal speakers.

Greet · 08-01-2011, 10:46 AM

Hi. I'm having some trouble configuring my the sound on my laptop. I'm using Alsa.
The problem is as follows.
Playing sound is no problem, but when I plug my Koss headphones into the audio jack the laptop speakers continue playing and sound also comes out of my headphones. When I go to alsamixer from cli the sound card only shows 1 master channel so I can't mute the internal laptop speakers.

My specs are.
Lenovo Ideapad s205
Amd Fusion e-350
Crunchbang Statler openbox
Squeeze kernel
2.6.32-5-amd64

I would be okay with completely disabling the internal laptop speakers if that is the easiest solution.

/proc/asound/cards

Code:

 0 [Generic        ]: HDA-Intel - HD-Audio Generic
                      HD-Audio Generic at 0xf0244000 irq 19
 1 [SB             ]: HDA-Intel - HDA ATI SB
                      HDA ATI SB at 0xf0240000 irq 16

/etc/modprobe.d/alsa-base.conf

Code:

# autoloader aliases
install sound-slot-0 /sbin/modprobe snd-card-0
install sound-slot-1 /sbin/modprobe snd-card-1
install sound-slot-2 /sbin/modprobe snd-card-2

install sound-slot-4 /sbin/modprobe snd-card-4
install sound-slot-5 /sbin/modprobe snd-card-5

options snd-pcsp index=-2
# Keep snd-usb-audio from beeing loaded as first soundcard

I don't know if these files are to any help but I'm not sure where to look.

Hello,

Try adding the following to the very end of your alsa-base.conf file:

Code:

options snd-hda-intel model=auto

After that, run the following:

Code:

sudo alsa force-reload

Now besides trying to auto-detect your device, you can use the following two sites and try to match your device with the correct settings within the lists.

Hope that helps man!

Ahhh thank you very much!!
After many tries I finally come by this post in the thread you linked. post #131
http://ubuntuforums.org/showthread.p...043568&page=14

I downloaded hda-verb from ftp://ftp.suse.com/pub/people/tiwai/...erb-0.3.tar.gz.
Then did

Code:

sudo hda-verb /dev/snd/hwC1D0 0x1f 0x701 1

That turned of the internal speakers so that sound only comes out of the headphones.
Now I'm a happy man! I almost started to believe that I would have to go back to Windows.

Awesome, glad to hear you got it working. I was thinking about going that route, but I wasn't sure if that would do it for your system. Kudos on the find!

Cheers,

Josh
