 Posted: Tue Mar 30, 2021 1:09 pm Post subject: Problem in sound output |
 |
|
Hello,
I have installed Gentoo on an intel ncu PC. I followed instructions about ALSA in Gentoo wiki page, but I have not been successful so far. My main problem is that I hear nothing when I play a .wav file neither from speakers nor from a headphone.
Some info about the system:
| Code: | $ aplay -L
null
Discard all samples (playback) or generate zero samples (capture)
lavrate
Rate Converter Plugin Using Libav/FFmpeg Library
jack
JACK Audio Connection Kit
pulse

And also playing a .wav file shows no error, but it has no sound

Hi
please emerge alsa-utils
run
alsamixer
use F6 to choose your card and umute it if muted and adjust the volume for "master"

Thanks for the hint. I have done all, but the issue has not been resolved yet.
<F6> in alsamixer shows the following device

I've also create the .asoundrc config file with the following content
| Code: | pcm.!default {
type hw
card 0
}
ctl.!default {
type hw
card 0
}

yet the sound is not heard. |

h.shahbazi,
Post the following please.

The output of
All of would be good too.

what is the output of
uname -r
?
Also please try
emerge -av sof-firmware linux-firmware
and an initrd to load them @boot
Also
intel-microcode ####and

h.shahbazi,
That looks good. You have exactly one sound card, so the default device works for you.
Your .asoundrc config file is not required.
Is your sound card codec configured correctly?
Please put the output of dmesg onto a pastebin site.
Also your kernel .config file.
The output of may help find a beginners mistake. Building one kernel a running a different kernel is easy to do.
I get
| Code: | $ uname -a
Linux NeddySeagoon_Static 5.11.2-gentoo #2 SMP PREEMPT Fri Mar 5 10:13:14 GMT 2021 x86_64 AMD Phenom(tm) II X6 1090T Processor AuthenticAMD GNU/Linux |
The Fri Mar 5 10:13:14 GMT 2021 is the build time of the running kernel.
In your uname -a output, does that look correct.

I'm quite sure the kernel was build and booted successfully. You can find content of the .config file as well as the kernel message here: https://gist.github.com/hassan-shahbazi/ffd8b3b2143ae4062f792be3b10fd0d3 |

h.shahbazi,
There are varying degrees of 'success' in building and booting a kernel. Some work better than others.
Your sound-hda-intel is fully modular, that works. Fully built in works too. Some parts built in, some parts modular fails as all the parts are required to initialise the driver.
| Code: | | [ 0.000000] Linux version 5.4.97-gentoo-x86_64 (root@gentoo) (gcc version 10.2.0 (Gentoo 10.2.0-r5 p6)) #2 SMP Wed Mar 31 00:51:02 EEST 2021 |
You rebuilt your kernel about 01:00 your local time. That matters to your helpers as we don't know what changed.
It may have invalidated other things you have posted.
Why do you have | Code: | | snd_hda_intel.dmic_detect=0 |
on the kernel command line?
| Code: | modinfo snd-hda-intel
parm: dmic_detect:Allow DSP driver selection (bypass this driver) (0=off, 1=on) (default=1); deprecated, use snd-intel-dspcfg.dsp_driver option instead (bool) |
Better yet, remove it altogether.
The driver found | Code: | | [ 5.478007] snd_hda_codec_realtek hdaudioC0D0: autoconfig for ALC256: line_outs=1 (0x21/0x0/0x0/0x0/0x0) type:hp |
The ALC256 is your audio codec.

Set those four sliders to about 70% then test.

Maybe also you try with the
5.10.x kernels........

on the kernel command line?
| Code: | modinfo snd-hda-intel
parm: dmic_detect:Allow DSP driver selection (bypass this driver) (0=off, 1=on) (default=1); deprecated, use snd-intel-dspcfg.dsp_driver option instead (bool) |
Better yet, remove it altogether.
|
It was advised in a few comments above. Anyway, I have removed it for the new kernel.

The ALC256 is your audio codec.
What does alsamixer show?
Top left is my codec | Code: | | │ Chip: VIA VT1708S |
At the bottom of the sliders are Mute Switches. OO means Open. MM means muted.
Mute all switches. Open only Master, Headphones, PCM and Front.
Set those four sliders to about 70% then test. |
The alsamixer output is like below

I can hear nothing yet from the headphone nor from the speaker (I'm not even sure Intel NCU contains speakers). However, I can feel something is connected for just 1 second (like you play an empty file) and then everything gets disconnected again. |

h.shahbazi,
Your sound card can work at the 44.1kHz sample rate for CDs, *.wav and so on and the 48kHz used by DVDs and later for digital audio.
Unfortunately, it can only do one or the other, not both at the same time.
When both are selected, digital audio wins and analogue stays silent.
Your alsamixer shows
| Code: | │ ├──┤ └──┘ ┌──┐ ┌──┐ ┌──┐ ┌──┐ ┌──┐ └──┘ └──┘ │
│ │MO│ │OO│ │MM│ │MM│ │MM│ │MM│ │
│ └──┘ └──┘ └──┘ └──┘ └──┘ └──┘ │
│ 83<>78 75<>75 53<>53 53<>53 │
│ < Master > PCM S/PDIF S/PDIF 1 S/PDIF 2 S/PDIF 3 S/PDIF 4 Internal Mic B Internal Mic B │
│ │ |
All the S/PDIF controls must be muted or your sound output is directed to the digital output.

The problem is that the S/PDIF changes back to mute right after "aplay a.wav". This is probably why the headphone gets completely mute in a second!
Is there any way to completely disable S/PDIF? That might resolve the issue |
