[SOLVED] Sound Not Working On Dell Latitude e5540 Laptop

Hello Everyone,

  I am having trouble getting sound working on my Dell Latitude e5540 laptop. When I try speaker-test or aplay, I get:

speaker-test 1.0.28

Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave
Playback open error: -2,No such file or directory

aplay -D default debussy-sb-clairdelune-breemer.wav

ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave
aplay: main:722: audio open error: No such file or directory

Here are my settings:

aplay -L | grep :CARD

hdmi:CARD=HDMI,DEV=0
hdmi:CARD=HDMI,DEV=1
hdmi:CARD=HDMI,DEV=2
default:CARD=PCH
sysdefault:CARD=PCH
front:CARD=PCH,DEV=0
surround21:CARD=PCH,DEV=0
surround40:CARD=PCH,DEV=0
surround41:CARD=PCH,DEV=0
surround50:CARD=PCH,DEV=0
surround51:CARD=PCH,DEV=0
surround71:CARD=PCH,DEV=0 

(My Realtek sound card that I want to use with the built in speakers is 1 in this listing)

aplay -l

**** List of PLAYBACK Hardware Devices ****

(I tried "card PCH" here too)

cat /etc/asconf.confpcm.!default {

}

}

Any help would be appreciated.

Do you have a ~/.asoundrc file?

Re: [SOLVED] Sound Not Working On Dell Latitude e5540 Laptop

I am using /etc/asconf.conf. Do I need a ~/.asoundrc too? I tried "card PCH" in /etc/asconf.conf along with "1".

cat /etc/asconf.conf

pcm.!default {
    type hw
    card 1 
}

ctl.!default {
    type hw
    card 1 
}

Re: [SOLVED] Sound Not Working On Dell Latitude e5540 Laptop

Maybe try putting this in for ~/.asoundrc and see if it works after a reboot?

defaults.pcm.card 1
defaults.pcm.device 0
defaults.ctl.card 1

Also make sure you're unmuted.  run alsamixer, press F6, select card, and ensure it is not muted and volume is up.

I got it working. The /etc/asconf.conf file should be /etc/asound.conf.

Haha, great catch.  Didn't even notice the wrong spelling.  You should update the thread title by editing the first post and marking it as [ Solved ]
