Getting your soundcard to work, using Debian on non-i386 hardware, etc

No sound from speakers (OK through headphones)

Postby littlebigman » 2017-04-10 08:02

Hello

I'm running LXDE Debian 8.7 on an Asus 1001PXD notebook.

Sound plays fine through headphones but I get no sound through the built-in speakers. Google didn't help so far, and am reluctant to try things for other distros in case I make things worse.

Here's some infos:
Code: Select all
Alsa Mixer just says "Card: PulseAudio" and "Chip: PulseAudio". There are no menus I could open.

# cat /proc/asound/cards
 0 [Intel          ]: HDA-Intel - HDA Intel
                      HDA Intel at 0xf7cf8000 irq 44
                     
# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC269VB Analog [ALC269VB Analog]
  Subdevices: 1/1

ii  xmms2-plugin-alsa                     0.8+dfsg-12                          amd64        XMMS2 - ALSA output


Any idea what I could try?

Thank you.

Edit: Posts on the net seem to say that the issue could come from the fact that this audio chip is incorrectly reported as from Intel while it's actually from Realtek:
Code: Select all
# head -n 1 /proc/asound/card*/codec#*

Codec: Realtek ALC269VB


I also tried creating a .asoundrc file, but still no sound:
Code: Select all
# aplay -L

front:CARD=Intel,DEV=0
    HDA Intel, ALC269VB Analog
    Front speakers

# echo 'pcm.!default front:Intel' > ~/.asoundrc

# aplay ./acme.mp3
Playing raw data './acme.mp3' : Unsigned 8 bit, Rate 8000 Hz, Mono
aplay: set_params:1233: Sample format non available
Available formats:
- S16_LE
- S32_LE

Seem alsa-XXX package is not powerful for multi-sound case
Maybe you can try uninstall alsa-XXX package then install "pavucontrol" to replace it
I'm sorry for my stupid English ability

Have you tried alsamixer? Maybe the speakers (or another channel) are muted?
