PATCH 1/1 Sigmatel stac92hd71b7 low HP volume

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

Hello,
I'm sure that the audioquality will degrade somewhat because of the additional amplification, but before, the HP-out was not usable at all. I had to use an external ampli just to use my headphones, even after turning all volume sliders to 100%. Then again, when removing the HP, the volume though the internal speakers was way too loud...

I'm not sure what you mean with the output pin and headphone control, but I have uploaded the output of the codegraph tool before and after my modification here:
http://users.vtk.be/~s0159120/codec_original.svg
http://users.vtk.be/~s0159120/codec_final.svg
Below is the output of alsa-info with the patched module Klaas

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:

Quoted 3 lines

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?

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.
Quoted 8 lines
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

Hello,
I'm sure that the audioquality will degrade somewhat because of the additional amplification, but before, the HP-out was not usable at all. I had to use an external ampli just to use my headphones, even after turning all volume sliders to 100%. Then again, when removing the HP, the volume though the internal speakers was way too loud...
I'm not sure what you mean with the output pin and headphone control, but I have uploaded the output of the codegraph tool before and after my modification here:

Below is the output of alsa-info with the patched module Klaas
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.

That is correct.

Quoted 7 lines

In the alsa-info.sh output, I see the following:
Quoted 3 lines
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?

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.

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.
Quoted 8 lines
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

Hello,
I'm sure that the audioquality will degrade somewhat because of the additional amplification, but before, the HP-out was not usable at all. I had to use an external ampli just to use my headphones, even after turning all volume sliders to 100%. Then again, when removing the HP, the volume though the internal speakers was way too loud...
I'm not sure what you mean with the output pin and headphone control, but I have uploaded the output of the codegraph tool before and after my modification here:

Below is the output of alsa-info with the patched module Klaas
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.
That is correct.
Quoted 5 lines
In the alsa-info.sh output, I see the following:
Quoted 3 lines
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?
No, after the patch I don't need 100% anymore.

Of course not :)

Quoted 4 lines

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.

Could you check the raw value of the widget 0x10 without your patch? The percent doesn't tell you exactly what you changed.

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.

Hello,
I'm sure that the audioquality will degrade somewhat because of the additional amplification, but before, the HP-out was not usable at all. I had to use an external ampli just to use my headphones, even after turning all volume sliders to 100%. Then again, when removing the HP, the volume though the internal speakers was way too loud...
I'm not sure what you mean with the output pin and headphone control, but I have uploaded the output of the codegraph tool before and after my modification here:

Below is the output of alsa-info with the patched module Klaas
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.
That is correct.

In the alsa-info.sh output, I see the following:

which means that you decrease the output level intentionally. Is the HP output still too low even if you set to the higher value?
No, after the patch I don't need 100% anymore.
Of course not :)
Quoted 4 lines
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.
Could you check the raw value of the widget 0x10 without your patch? The percent doesn't tell you exactly what you changed.

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.

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.

Quoted 7 lines

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...

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.

thanks,

Hello,
I'm sure that the audioquality will degrade somewhat because of the additional amplification, but before, the HP-out was not usable at all. I had to use an external ampli just to use my headphones, even after turning all volume sliders to 100%. Then again, when removing the HP, the volume though the internal speakers was way too loud...
I'm not sure what you mean with the output pin and headphone control, but I have uploaded the output of the codegraph tool before and after my modification here:

Below is the output of alsa-info with the patched module Klaas
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.
That is correct.

which means that you decrease the output level intentionally. Is the HP output still too low even if you set to the higher value?
No, after the patch I don't need 100% anymore.
Of course not :)

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.
Could you check the raw value of the widget 0x10 without your patch? The percent doesn't tell you exactly what you changed.

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.

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.

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.

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...
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.

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.
