[SOLVED] Audio plays only in front speakers

My laptop DEXP Atlas m14-inw304 (in BIOS it is called Hena m14) has 4 speakers: two in front, two on the bottom edge. The system sees only 2 front speakers, which is why the sound becomes simply terrible.

I'm using pipewire and the latest kernel (6.15.9-arch1-1) and KDE Plasma 6.4.4

If it helps, here is the output of the

aplay -l

command

**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC269VB Analog [ALC269VB Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 7: HDMI 1 [HDMI 1]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

  Subdevices: 1/1

and

speaker-test -c 4

speaker-test 1.2.14

Playback device is default
Stream parameters are 48000Hz, S16_LE, 4 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 32 to 524288
Period size range from 16 to 262144
Periods = 4
was set period_size = 12000
was set buffer_size = 48000
 0 - Front Left
 1 - Front Right
 3 - Rear Right
 2 - Rear Left

It plays on the front speakers, and then plays back on the front speakers, but a little quieter.
Also, on KDE sound settings it looks like "Analogue Stereo Duplex", and has only 2 channels.

I apologize in advance for my possibly bad English, I use a translator as it is not my native language

Re: [SOLVED] Audio plays only in front speakers

Fixed this by changing pins 0x1a and 0x1b to Internal Speakers (Back) in hdajackretask from alsa-tools.
