Hi,
I have a sound problem with my dell1400 laptop: I have no sound from
the speakers in the laptop but I can have sound from headphones after
I insert them.

When I used $alsamixer -V all, I got these informations:

Card: HDA Intel                                                              │
Chip: SigmaTel STAC9228                                                      │
View:  Playback  Capture [All]                                               │
Item: Master [dB gain=-33.75, -33.75]
Item: PCM [dB gain=-10.00, -10.00]
Item: Front [dB gain=-45.00, -47.25]
Item: Mic as Output
Item: IEC958
Item: ADCMux
Item: InMux [dB gain=30.00, 30.00]
  Item: InVol [dB gain=16.50, 16.50]

As you can see, Mic and IEC958's values are both 0.

I always think that headphones are equal with speakers, because  them
are both connected to the same thing in physics.
But now, why my headphones are aloud but my speakers are silent.
In Windows xp, both of them work very well. Headphones were after I
insert them and otherwise, the speakers loud .

How to fix this problem?
Thanks in advanced!

Mark, I think this problem is on your end possibly. I got the

Chuanwen: Personally I have never encountered a situation where on a
laptop the volume control etc. is different between the attached
speakers and headphones. I've always assumed (someone correct me if I
am wrong) that the switching between headphones and the attached
speakers is hardware and not software. If that is the case then you
might have a hardware issue.

On the other hand, I am not sure how to read your alsamixer output.
Perhaps post output from 'amixer'?

We probably can't see what you're describing.  Can you unmute one at a time or 
increase their volume to check if someting gives?

I too thought that this is a hardware issue . . .

You may want to look at other sigmatel/hda-intel issues to see what 
you need to report to get things moving.  Also first try using the 
very latest alsa-lib and alsa-driver packages.

This is true; the headphone jacks usually have an integrated disconnect
switch for the internal laptop speakers, to be tripped when a plug is
inserted.

I doubt it, since they work in windows.  More likely, this new-ish
sound card is going to require a bit of tweaking to get working
properly.

It too think this would be very helpful.  amixer will list each of the
device controls, so we can see if it's just a simple unmuting of
something you missed (i doubt it).

I am very sorry that brought you guys the inconvenience. I am very
surprise, too. Just as what I usually do, I opened the firefox,
logined my gmail account, then wrote and sent out the email which you
have received.

As you know, the output of alsamixer is in graphics mode, so  I felt
very uncomfortable when I described this problem and selected the
information from alsamixer. I appology for this.
Thanks goodness we have  amixer:

You can see above that, I have set the largest volume(100%) except the
"Mic as Output" and 'IEC958' and 'ADCMux', I am not very sure what
their functions are when controlling  my sound card.

I also consider the switching  between headphone and speakers attached
as hardware. So I am also surprised when I found this problem.


I use the Alsa-driver-1.0.14-rc3, which is a unstable one. And the
weird thing is that *ONLY* this version's driver can drive my sound
card. I also tried the in-kernel(2.6.22-r2) one; the version 1.0.14,
which is the newest stable one that came out after 1.0.14-rc3, and
also the 1.0.15-rc2 one.
But none of them work.

It's apparently no longer true, at least for newish Intel HDA
chipsets.  Mine (SigmaTel STAC9872AK) would not switch off the internal
speakers when the jack was plugged in, so sound would come from both
the headphones and the speakers.  A recent patch to the driver fixed
this.

Sorry this doesn't help the OP any.

Maybe the certificate acceptance question window is hiding somewhere

So, which version of alsa-driver do you think can fixed this?
I have tried version 1.0.15-rc2, but that didn't work, I meant I even
can't use the headphones.
I use 1.0.14-rc3 now, which at least let my headphones work.
