No Sound Clear Linux

I installed clear linux but I have no sound. I've never been an expert on sound, so I could really use some help.

Pulse Audio is installed.

I was using clear linux irc and tried a couple of suggestions, but now, it seems worse off.

There is a couple of points, that I think will point the more knowledgeable directly to the problem.

First, when I open alsamixer I pulse audio is selected as the default but the on board sound was listed under F6 but it never seemed to save after I changed it. Now after some fiddling it doesn't even show the onboard.

secondly, aplay -l and aplay -L show nothing unless run as root.

I ran alsa-info.sh which seems to give a ton of information which is here

When you say that you have no sound - what device are you trying to listen via. I note that the HDMI audio device is the first audio device listed. An easy way to configure the audio subsystem is to use the 'pavucontrol' (PulseAudio Volume Control) GUI utility. There you can configure the desired profile.

The following command will also show the profiles available, and current active profile

Code:

pacmd list sinks

I'm trying to get any sound. I don't currently have an HDMI output (physical). I'm just trying to use the onboard sound via the 3.5mm female output.

I've tried a wav file via aplay. I've tried speaker-test. I've tried playing video's on YouTube. I've tried vlc/cvlc.
I believe gnome plays something when starting. Nothing

from pacmd list sinks

0 card(s) available.
0 sink input(s) available.
0 source output(s) available.
0 cache entrie(s) available.

Ok, that’s a little more specific. Details are important.

Can you elaborate on this? Otherwise this will just be a guessing game.

You appear to have a permission-related issue going on here. With some distros ACLs are used, but others may still require the user to be a member of the 'audio' group

This might tell us more...

Code:

ls -l /dev/snd/*

Code:

getfacl /dev/snd/*

For example, openSUSE uses ACLs, so I get

Code:

ls -l /dev/snd/*

crw-rw----+ 1 root audio 116,  2 Nov 11 08:00 /dev/snd/controlC0

crw-rw----+ 1 root audio 116,  4 Nov 11 08:00 /dev/snd/pcmC0D0c

crw-rw----+ 1 root audio 116,  3 Nov 12 10:22 /dev/snd/pcmC0D0p

crw-rw----+ 1 root audio 116,  5 Nov 11 08:00 /dev/snd/pcmC0D1c

crw-rw----+ 1 root audio 116,  1 Nov 11 08:00 /dev/snd/seq

crw-rw----+ 1 root audio 116, 33 Nov 11 08:00 /dev/snd/timer

The + sign indicates that the files have ACLs attached to them. If yours don't then the user will need to be a member of the appropriate group (usually the 'audio' group for sound).

Fore reference, my getfacl output (with openSUSE Leap) for /dev/snd/<files> looks like this

Code:

# file: dev/snd/controlC0

# owner: root

# group: audio

user::rw-

user:dean:rw-

group::rw-

mask::rw-

other::---

The manpage for getfacl explains....

Quote:

For each file, getfacl displays the file name, owner, the group, and the Access Control List (ACL). If a directory has
a default ACL, getfacl also displays the default ACL. Non-directories cannot have default ACLs.

ferrari,

Thank YOU! Thank YOU! Thank YOU!

I've never dealt with ACL before. It was completely new to me.

I'm not sure what's going on with groups. I first tried to add myself to the audio group but that didn't fix the issue and ... I don't understand why id didn't pick it up.

Code:

larry@clear ~ $ id

uid=1000(larry) gid=1000 groups=1000,10(wheel),307(pulse)



larry@clear ~ $ cat /etc/group

wheel:x:10:larry

pulse:x:307:larry

audio:x:63:larry

But.... this rocked it!

Code:

sudo setfacl -m "u:larry:rw-" /dev/snd/*

now SOUND!

Thank YOU!

I don't know if I did things properly or not...(probably not) but least I have sound!

It is necessary to logout and back in before such a change is effective.

Usually, I would expect a udev rule to take care of setting access (depending on whether consolekit or udev is managing such things). I don't know anything about Clear Linux, so can't advise specifically here. Anyway, hopefully your manual ACL configuration won't be changed via another subsystem or updates.
