HI,
I'm not able to ear any sound from my panel pc. It has a Gentoo kernel 3.19.8 and the sound hardware is the following:
Code:
eposatom ~ # aplay -L
null
    Discard all samples (playback) or generate zero samples (capture)
default:CARD=PCH
    HDA Intel PCH, ALC262 Analog
    Default Audio Device
sysdefault:CARD=PCH
    HDA Intel PCH, ALC262 Analog
    Default Audio Device
front:CARD=PCH,DEV=0
    HDA Intel PCH, ALC262 Analog
    Front speakers
surround21:CARD=PCH,DEV=0
    HDA Intel PCH, ALC262 Analog
    2.1 Surround output to Front and Subwoofer speakers
surround40:CARD=PCH,DEV=0
    HDA Intel PCH, ALC262 Analog
    4.0 Surround output to Front and Rear speakers
surround41:CARD=PCH,DEV=0
    HDA Intel PCH, ALC262 Analog
    4.1 Surround output to Front, Rear and Subwoofer speakers
surround50:CARD=PCH,DEV=0
    HDA Intel PCH, ALC262 Analog
    5.0 Surround output to Front, Center and Rear speakers
surround51:CARD=PCH,DEV=0
    HDA Intel PCH, ALC262 Analog
    5.1 Surround output to Front, Center, Rear and Subwoofer speakers
surround71:CARD=PCH,DEV=0
    HDA Intel PCH, ALC262 Analog
    7.1 Surround output to Front, Center, Side, Rear and Woofer speakers
hdmi:CARD=PCH,DEV=0
    HDA Intel PCH, HDMI 0
    HDMI Audio Output
hdmi:CARD=PCH,DEV=1
    HDA Intel PCH, HDMI 1
    HDMI Audio Output
hdmi:CARD=PCH,DEV=2
    HDA Intel PCH, HDMI 2
    HDMI Audio Output


The .asoundrc file is the following:
Code:
# alsa configuration file

pcm.hda-intel{
        type hw
        card 0
        }
ctl.hda-intel{
        type hw
        card 0
        }


The kernel has the following drivers:
Code:
eposatom ~ # zgrep -i snd_hda /boot/config-3.19.8-gentoo
CONFIG_SND_HDA=y
CONFIG_SND_HDA_INTEL=y
CONFIG_SND_HDA_PREALLOC_SIZE=64
CONFIG_SND_HDA_HWDEP=y
# CONFIG_SND_HDA_RECONFIG is not set
# CONFIG_SND_HDA_INPUT_BEEP is not set
# CONFIG_SND_HDA_INPUT_JACK is not set
# CONFIG_SND_HDA_PATCH_LOADER is not set
CONFIG_SND_HDA_CODEC_REALTEK=y
CONFIG_SND_HDA_CODEC_ANALOG=y
CONFIG_SND_HDA_CODEC_SIGMATEL=y
CONFIG_SND_HDA_CODEC_VIA=y
CONFIG_SND_HDA_CODEC_HDMI=y
CONFIG_SND_HDA_I915=y
CONFIG_SND_HDA_CODEC_CIRRUS=y
CONFIG_SND_HDA_CODEC_CONEXANT=y
CONFIG_SND_HDA_CODEC_CA0110=y
CONFIG_SND_HDA_CODEC_CA0132=y
# CONFIG_SND_HDA_CODEC_CA0132_DSP is not set
CONFIG_SND_HDA_CODEC_CMEDIA=y
CONFIG_SND_HDA_CODEC_SI3054=y
CONFIG_SND_HDA_GENERIC=y


Finally the alsa.conf file is the following
Code:
# Alsa kernel modules' configuration file.

# ALSA portion
alias char-major-116 snd
# OSS/Free portion
alias char-major-14 soundcore

##
## IMPORTANT:
## You need to customise this section for your specific sound card(s)
## and then run `update-modules' command.
## Read alsa-driver's INSTALL file in /usr/share/doc for more info.
##
##  ALSA portion
## alias snd-card-0 snd-interwave
## alias snd-card-1 snd-ens1371
alias snd-card-0 snd-hda-intel
##  OSS/Free portion
## alias sound-slot-0 snd-card-0
## alias sound-slot-1 snd-card-1
##

# OSS/Free portion - card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
##  OSS/Free portion - card #2
## alias sound-service-1-0 snd-mixer-oss
## alias sound-service-1-3 snd-pcm-oss
## alias sound-service-1-12 snd-pcm-oss

alias /dev/mixer snd-mixer-oss
alias /dev/dsp snd-pcm-oss
alias /dev/midi snd-seq-oss

# Set this to the correct number of cards.
options snd cards_limit=1
options snd_hda_intel index=0 model=inv-dmic


The alsasound service has been enabled at boot
The system works under X without any windows manager but with a specific GUI application.


Do you have any suggestion to give me to let the audio work?

Thanks
Claudio

Does it work if you use a recent kernel? Has it ever worked on this system?

I tried using the last live dvd version and it works using amarok.
The difference is that into the live there is pulseaudio running. In my system pulseaudio is not present
The command "aplay" doesn't work properly in both the devices: with the live dvd I ear only noise, with the device I don't ear anything

Update:

Sending the command: dmesg | grep audio I was seeing this answer:
Code:
eposatom ~ # dmesg | grep audio
[    2.486249] sound hdaudioC0D0: autoconfig: line_outs=1 (0x14/0x0/0x0/0x0/0x0) type:speaker
[    2.486253] sound hdaudioC0D0:    speaker_outs=0 (0x0/0x0/0x0/0x0/0x0)
[    2.486255] sound hdaudioC0D0:    hp_outs=1 (0x15/0x0/0x0/0x0/0x0)
[    2.486257] sound hdaudioC0D0:    mono: mono_out=0x0
[    2.486258] sound hdaudioC0D0:    inputs:
[    2.486260] sound hdaudioC0D0:      Internal Mic=0x19
[    2.486261] sound hdaudioC0D0:      Mic=0x18


I tried to rebuild the kernel with the alsa driver as module and removing the useless drivers. Now the result of the command is:
Code:
eposatom ~ # dmesg | grep audio
[    2.486249] sound hdaudioC0D0: autoconfig: line_outs=1 (0x14/0x0/0x0/0x0/0x0) type:speaker
[    2.486253] sound hdaudioC0D0:    speaker_outs=0 (0x0/0x0/0x0/0x0/0x0)
[    2.486255] sound hdaudioC0D0:    hp_outs=1 (0x15/0x0/0x0/0x0/0x0)
[    2.486257] sound hdaudioC0D0:    mono: mono_out=0x0
[    2.486258] sound hdaudioC0D0:    inputs:
[    2.486260] sound hdaudioC0D0:      Internal Mic=0x19
[    2.486261] sound hdaudioC0D0:      Mic=0x18
[    2.492578] sound hdaudioC0D2: autoconfig: line_outs=0 (0x0/0x0/0x0/0x0/0x0) type:line
[    2.492582] sound hdaudioC0D2:    speaker_outs=0 (0x0/0x0/0x0/0x0/0x0)
[    2.492584] sound hdaudioC0D2:    hp_outs=0 (0x0/0x0/0x0/0x0/0x0)
[    2.492585] sound hdaudioC0D2:    mono: mono_out=0x0
[    2.492586] sound hdaudioC0D2:    dig-out=0x3/0x0
[    2.492588] sound hdaudioC0D2:    inputs:


In any case nothing changed: no sound
