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

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

Any help would be appreciated.

Do you have a ~/.asoundrc file?

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
}

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 ]

O.k. I updated the title.
