have sound on internal speakers but not on headphone line-out

Hey guys,

I have been running Arch linux on my secundairy laptop for a while now. I primarily use it as a webserver but recently started to use it as a airplay speaker with shairport. Shairport is working just fine and I can play sound from my ipod touch trough my internal speakers, but not trough the hooked up amplifier. I seem to be getting no sound at all trough my headphone audio line-out.

I am using an old micropoint laptop.

# uname -a
Linux _hostname_ 3.3.1-1-ARCH #1 SMP PREEMPT Tue Apr 3 14:43:38 UTC 2012 i686 Mobile Intel(R) Pentium(R) 4 - M CPU 1.80GHz GenuineIntel GNU/Linux

And I have a SiS SI7012 soundcard with a realtek ALC202 chipset.

# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: SI7012 [SiS SI7012], device 0: Intel ICH [SiS SI7012]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: Modem [SiS SI7013 Modem], device 0: Intel ICH - Modem [SiS SI7013 Modem - Modem]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

I've already read a lot of posts about the same problem, but no solutions have solved my problem. Most posts say I should set my model but I can't find my chipset in http://www.kernel.org/doc/Documentation … Models.txt so I have no idea what model I should set it to.

Could somebody please help me, I'm quite desperate after a lot of hours of problem solving?
Thanks

Re: have sound on internal speakers but not on headphone line-out

Is there asomething like IEC958 Capture Monitor in alsa-mixer? Have you tried unmuting everything except this device?

Re: have sound on internal speakers but not on headphone line-out

yes, Miau, I do have a capture device and unmuted everything except for the capturing device, but the only result was that my internal speakers began squeaking due to the microphone boost.So I remuted that. But still no headphone sound.

Here is my amixer output.

I see no headphone device in amixer, I still think that is caused by my model setting, but I can't find my model name because of my exotic old laptop.

Re: have sound on internal speakers but not on headphone line-out

Which sound module do you use? Have you tried unmuting some of the other channels, like Line Jack Sense?

No i meant which sound module you are using. What's the output of

lsmod | grep snd

? Have you tried muting the external Amplifier in alsamixer?

Re: have sound on internal speakers but not on headphone line-out

oh you mean snd-intel8x0
the output from lsmod is:

# lsmod | grep snd
snd_intel8x0           22872  0 
snd_intel8x0m           9575  0 
snd_ac97_codec         90085  2 snd_intel8x0m,snd_intel8x0
ac97_bus                 842  1 snd_ac97_codec
snd_pcm                60723  3 snd_ac97_codec,snd_intel8x0m,snd_intel8x0
snd_page_alloc          5869  3 snd_pcm,snd_intel8x0m,snd_intel8x0
snd_timer              15470  1 snd_pcm
snd                    45057  5 snd_timer,snd_pcm,snd_ac97_codec,snd_intel8x0m,snd_intel8x0
soundcore               5018  1 snd

But I've checked that and it is the right module for my soundcard (SiS7012)
