Subject description: I known the solution in others distros (ubuntu). how fix it in Ubuntu Bionic 64
 

Hello all,

I'm new and beginner in this world of linux. Like others i've got a old laptop (my wife really) with integrated audio. The sound is clear but very low (yes, i change the values of pcm, and others in alsamixer).

The solution 'is easy', but i don't know how i can operate it in Bionic Puppy. I need to change one node, the number 0x26 (pin complex) in the sound driver. In other distros i can use the HDA_ANALYZER, a friendly front that can operate on this values, even create a Python script with the code.

The necesary changes in the node 0x26 are:

- set eapd-btlenable (EAPD 0X0 ----> EAPD 0X2: EAPD)
- set_pin_widget_control (Pin-ctls:0x0 ---> Pin-ctls: 0x60: IN OUT)

Welcome Luisan86!

Search pkg manager for "alsa-tools-gui" -- install it and any dependencies..

Then in Pups Multimedia menu fire up hdajackretask. Does it find your codec?

Thanks Semme

Yes, i saw this app but i discarded it because don't recognize my codec, or any codec.

I'll retake this via and i'll try to fix the problem with hdakjackretask. Perhaps the solution began with the jackretask.

Do you known a solution for the unrecognized codec?

Thanks again

Hi, again

i've checked the dependencies installed package, for the alsa-tool-gui. i've got a missing library: libfltk.so.1.1.

if i search, using the puppy package manager, the library libfltk, all listed are installed, but no one is exactly the libfltk.so.1.1.

Perhaps this is the bug for my messages 'no codecs found'.

By the way, i'm using the distro puppy in a USB with personal storage...

Best regards

Sometime we can add a symlink to an exiting lib. Please do
Code:
find /usr/lib/ /usr/lib64/ /usr/local/lib/ /usr/local/lib64/ | grep libfltk


post here the result

Luisan,

Based on what you've provided and the corrosponding info I've filtered through, I'm confident I've interpreted everything properly. There are ZERO typos. What I'd like you to do is confirm for yourself the file location for my alternate, or "second" method (/sys/class/sound/hwC0D0, your device). The only item I'm unsure of is that "reconfig" line, the third one in the second method. And who knows, maybe the first method resolves your issue.

You'll need to install "alsa-tools" from PPM before executing the commands in the first method.

#############
#############

Code:
hda-verb /dev/snd/hwC0D0 0x26 SET_EAPD_BTLENABLE 0x02
hda-verb /dev/snd/hwC0D0 0x26 SET_PIN_WIDGET_CONTROL 0x60

Reference

#############
#############

Code:
echo 0x26 0x26070c02 > /sys/class/sound/hwC0D0/user_pin_configs
echo 0x26 0x26070760 > /sys/class/sound/hwC0D0/user_pin_configs
echo 1 > /sys/class/sound/hwC0D0/reconfig

Reference

It'll work or it won't. There's NO luck involved.

I WILL however keep my fingers crossed. Very HappyWink

@ Luisan86:-

Perhaps this might help?

http://old-releases.ubuntu.com/ubuntu/pool/main/f/fltk1.1/libfltk1.1_1.1.10-19_amd64.deb

(Direct link to the most recent 64-bit libfltk .deb from /ubuntu/pool's "old-releases" repo, from 2014...)

Thanks Enrique

First, i've created a new USB with Puppy Ubuntu. Installed again the alsa-tools-gui, in this case with no error in library missing.

If i execute your command i obtain :

/usr/lib/libfltk_gl.so.1.1
/usr/lib/libfltk_images.so.1.1
/usr/lib/libfltk_forms.so.1.1
/usr/lib/libfltk.so.1.1
/usr/lib64/libfltk_gl.so.1.1
/usr/lib64/libfltk_images.so.1.1
/usr/lib64/libfltk_forms.so.1.1
/usr/lib64/libfltk.so.1.1
find: ‘/usr/local/lib64/’: No such file or directory

Thans too Semme

You gave me new paths to investigate. The commands, options, that you comment to me is used to modify the HwC0D0. That is the solution in Linux Mint using the alsa_analizer.

BUt, i readed that in Puppy Linux, i din't find it, don't exists that file (hwC0D0), due to Kernel using in this distro In fact, in the snd_hda_intel, in my puupy linux , contain the command config_snd_hda_hwdep=m. i try to change the value to 'y' but in this case obtain an error in that line with i force reload the alsa.

So that, i think that is not possible to force the system to create a hwC0D0.

When the hwC0D0 don't exists i suppose that the only option is the codec#0 (the driver) (proc/asound/card0/codec#0). But this file no accept the set-eapd commands and not is possible to edit and change manually this file.

And...this is my actual death line.

You're saying neither of those file locations exist aboard Pup? Bummer!

No worries, though, I have NO DOUBT that one of those cmds would work on *any* standard distribution.

Thanks to all.

It's true Semme. Other distros, standard, can fix the problem with your commands or using, if possible, the hda_analizer.

Puppy is so fast, but i'll have choose another light distro.

Thanks again.
