[Solved] Realtek ALC897 No sound with ALSA installed

[web.user]

Hello! I have integrated sound card in Intel-based motherboard. I reconfigured & rebuilt kernel, installed alsa-lib, alsa-utils, unmuted alsamixer, enabled alsa and sound useflags, reemerged @world, but still no sound (tested with speaker-test, mpv and firefox). The user is in audio group. I use headphones btw. How can I make audio work? Here is some relevant info:

lspci -vv | grep -i audio

I tried installing alsa-firmware, but it does not change anything (so I uninstalled it). Hardware is 100% working, tested on MX Linux livecd. I checked lsmod on it, snd_hda_intel is in use there (so on my system). I searched for a solution with no luck. Please help make it working.

You might want to try to compile SND as a module instead of built-in. On my system, this is somehow needed.

CONFIG_SND=m
CONFIG_SND_HDA=m
CONFIG_SND_HDA_CODEC_REALTEK=m

EDIT :
Also, tick this :
CONFIG_SND_HDA_RECONFIG=y

Thanks for reply, I compiled it as module, now lsmod shows many modules, but still no sound. By the way, I have selected HDA Intel PCH card by default

When I cat /proc/asound/timers with mpv running, it shows this:

Code: Select all

web.user,

What does

Code: Select all

/proc/asound/devices

contain?

What does

Code: Select all

ls -l /dev/snd

show?

With also built into the kernel, /etc/modprobe.d/alsa.conf cannot be consulted, as sound in stated before root is mounted.
Its probably not needed anyway.

All SND_HDA_INTEL cards are capable of operating with a 44.1kHz sample rate for CD Digital Audio or 48.0kHz for digital outputs but not both at the same time.
I get any analogue audio output at all, all the controls with IEC or S/PDIF is their names must be muted because that card will prioritise digital output over analogue output.

If alsa mixer shows a Headphone control, it may be swapped with one pair of speakers, possibly Front. Do not rely on the analogue output channel naming.

A good test process is to mute everything.
Now unmute only PCM, Master and Front. Set those sliders to about 70%.
Don't put the headphones over your ears - it might be very loud.
Now test.
Unmute other controls one at at time, Headphones, Side, Rear, Centre/LFE.

The test will fail if the things I asked for are not correct.

I tried to do that test, but I have no mute/unmute option for PCM. Thanks for suggestion to mute S/PDIF, but still no sound. Here is alsamixer:

When I try to play a music file with mpv, a very silent beep can be heared. The same sound when I plug headphones in/out. Also, this sound is made during boot.
Interestingly, unlike MX Linux, Ubuntu livecd doesn't have sound too.

Thanks everybody for help, it was my issue: I used wrong 3.5mm jack. Sorry for wasting time.
