Realtek ALC714 - No sound with Dell XPS 9320

[Chumi <michu8u@xxxxxxxxx>]

Hi,

I did not succeeded to have the sound on my laptop Dell XPS 9320. The specifications says that it has speakers.
But no sound from the headphone neither the speakers.

Note : when i enabled pulseaudio, the headphone is ok but not the speakers.

Here is the output from alsa-info.sh : https://alsa-project.org/db/?f=cf4458e8eaa8e9856adf9a0851e522801b13e49f

The bios version is the last one. My Kernel : 6.6.5-gentoo.
When F2 to access to the Bios, it show that the Audio chipset controller is ALC714 !

In my machine, Gentoo show as Intel Alder Lake PCH-P High Definition Audio.

Audio:
  Device-1: Intel Alder Lake Imaging Signal Processor vendor: Dell driver: N/A bus-ID: 00:05.0
    chip-ID: 8086:465d class-ID: 0480
  Device-2: Intel Alder Lake PCH-P High Definition Audio vendor: Dell driver: snd_hda_intel
    v: kernel alternate: snd_sof_pci_intel_tgl bus-ID: 00:1f.3 chip-ID: 8086:51c8 class-ID: 0401
  API: ALSA v: k6.6.4-gentoo status: kernel-api tools: alsactl,alsamixer,amixer
  Server-1: JACK v: 0.125.0 status: off tools: N/A
  Server-2: PulseAudio v: 16.1 status: off tools: pacat,pactl,pavucontrol

There is no ~/.asoundrc or /etc/asasound.conf file ; i stopped playing with my ~/.asoundrc.

grep -i codec /proc/asound/card*/codec*

Codec: Intel Alderlake-P HDMI

alsamixer -c1

Card: HDA Intel PCH
Chip: Intel Alderlake-P HDMI

There are only 4 volume controls : S/PDIF S/PDIF1 S/PDIF2 S/PDIF3
But you can not up or down the volume.

There is no sound from speaker-test -c.

I've tried these into /etc/modprobe.d/alsa.conf

options snd-hda-intel power_save=0

# \!/ if used, there is no cards detected
# forcing the second driver i.e. snd_sof_pci_intel_tgl
#options snd_intel_dspcfg dsp_driver=2
