Hello,
Below is my patch for an issue on Dell E6500 notebooks with the Sigmatel stac92hd71b7 codec. In the default snd-hda-intel configuration, the sound going to the headphone jack goes comes directly from the DAC, resulting in very low volume output. The patch changes the codec's widget connections so that the internal mixer is put in between and sets its input amplifiers to the maximum value. The output to the internal speaker port has been left untouched.
I have tested this and it gives a much better output.

Hello,
A few days ago, I posted a patch to the linux kernel list, but afterwards I realised that it is
more appropriate for the alsa list. So I repost it here.
Below is my patch for an issue on Dell E6500 notebooks with the Sigmatel stac92hd71b7 codec. In
the default snd-hda-intel configuration, the sound going to the headphone jack
goes comes directly from the DAC, resulting in very low volume output. The patch changes the
codec's widget connections so that the internal mixer is put in between and sets its
input amplifiers to the maximum value. The output to the internal speaker port has been left
untouched.
I have tested this and it gives a much better output.

Thanks for the patch.
I wonder whether this really improves the quality.
Basically what you does is to set the volume of the input mixer over
0dB, and this is usually bad when really high signals come in.
Just to be sure, is the output pin set to the headphone pin control?
You can give alsa-info.sh output (run with --no-upload option) for
further analysis. The script is found in
http://www.alsa-project.org/alsa-info.sh
thanks,
Takashi

Thanks.
So, if I understand correctly, when the pin 0x0a is connected directly
from DAC0 0x10, the output level is too low even if you set the all
volumes maximal. In the alsa-info.sh output, I see the following:
> Node 0x10 [Audio Output] wcaps 0xd0c05: Stereo Amp-Out R/L
> Amp-Out caps: N/A
> Amp-Out vals: [0x5e 0x5e]
which means that you decrease the output level intentionally.
Is the HP output still too low even if you set to the higher value?

That is correct.

No, after the patch I don't need 100% anymore. The HP output is fine
now, and I can tune it up and down a bit. Before using the mixer-amp,
going from 90 to 100 resulted in going from no sound to little sound.
Now the range is more useful.

I have pasted the output of /proc/asound/card0/codec#0 below, without
the patch. However, I'm not sure what you're exactly looking for? I'm
quite new to all this stuff , but I'd be more than happy to help out
more, so feel free to ask anything.
Also related, in windows (yeah i know), using the IDT drivers, the
volume is extremely high :) So I went searching in the driver files
and it seems that the widget configuration is specified there in an
ini file. As far as I can see, the mixer is not configured, but an
external amp is mentioned. Could it be that the external amp of 0x0A
is not used in snd-hda-intel? Or maybe it refers to the "+3dBV output
option on headphone capable ports" as mentioned in the datasheet...
But I'm just guessing now.

The mixer volume level in percentage might be different from the raw
value of the NID 0x10 (or 0x11?) amps because of volume-knob stuff.
I just wanted to make sure that a really high value is set to the
amp.
OTOH, if it happens only with the headphone (I suppose the loud enough
output from the speaker after unplugging the headphone), this isn't a
matter of the DAC amp value.

This seems to be the normal pin control bit 7 to me. And we already
set it.
BTW, you can use hda-verb program to change the verb dynamically.
Build the driver with CONFIG_SND_HDA_HWDEP=y, and you'll have the
access to hwdep device, e.g. /dev/snd/hwC0D0. The device number
depends on the codec slot.

But, with this information, can something be done about it in future
releases? Maybe a model-option?
I also checked the output by connecting earplugs and by using the jack
as lineout to my hifi, but it is again quite low-volume. So that rules
out a "bad" headphone.

Possibly. Or, it's a generic problem regarding volume-knob. It's not
ruled out yet.

I didn't doubt it. My question was "what is the raw value".
I don't trust the mixer percentage values you showed. They are
important in the end result, but not for analyzing the problem.
Instead, the raw values the driver sends to the codec are really raw
and more understandable. (And, for checking this, you can use
hda-verb program, too.)
So, if you try to analyze the problem, always check the values in
codec proc. At best, check the values directly by yourself via
hda-verb program.

The posts from non-subscribers have to be approved manually.
Just subscribe to the list first to reduce the latency.

In the default snd-hda-intel configuration, the sound going to the headphone jack goes comes directly from the DAC, resulting in very low volume output. The patch changes the codec's widget connections so that the internal mixer is put in between and sets its input amplifiers to the maximum value. The output to the internal speaker port has been left untouched.

This needed updating to apply on the current alsa development tree.
Please see below.
Note that this may now be wrong - various cases in
patch_stac92hd71bxx() have recently been updated to modify
codec->slave_dig_outs, but we're not doing that in the case of
0x111d76b2.
Please send us a Signed-off-by: for your patch, as per
Documentation/Submittingpatches, thanks.

Fix an issue on Dell E6500 notebooks with the Sigmatel stac92hd71b7 codec.
In the default snd-hda-intel configuration, the sound going to the
headphone jack goes comes directly from the DAC, resulting in very low
volume output. The patch changes the codec's widget connections so that
the internal mixer is put in between and sets its input amplifiers to the
maximum value. The output to the internal speaker port has been left
untouched. I have tested this and it gives a much better output.
