Hello everyone,

This thread is basically a copy of a Reddit thread here.

When I run

Code: Select all

play -n synth whitenoise gain -6

(requires sox to be installed and it might be loud), I get this error:

Code: Select all

└─$ play -n synth whitenoise gain -6
shm_open() failed: No such file or directory
ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Protocol error

play FAIL formats: can't open output file `default': snd_pcm_open error: Connection refused

So then I tried this:

Code: Select all

└─$  speaker-test

speaker-test 1.1.0

Playback device is default
Stream parameters are 48000Hz, S16_LE, 1 channels
Using 16 octaves of pink noise
shm_open() failed: No such file or directory
ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Protocol error

Playback open error: -111,Connection refused

So I thought hmm... this might be a PA issue, so then:

Code: Select all

└─$  pactl list
shm_open() failed: No such file or directory
Connection failure: Protocol error

I've also tried what this user was suggesting with the following results.

Meanwhile, VLC together with Chromium and Firefox do have audio. However, I can't play sound through mpv for example.

Try doing it as superuser/root
by prepending 'sudo …'.

If it works, check which groups exist
on Your system and which groups You are in.

Add Yourself to audio-related group(s).

ReadWrite-permissions for Your account
should normally be auto-configured:

Example:

$ cd /

$ getfacl dev/snd/controlC0
# file: dev/snd/controlC0
# owner: root
# group: audio
user::rw-
user:<Your-UserAccount-Name>:rw-
group::rw-
mask::rw-
other::---

Another reason could be that this file either is missing
or has wrong permissions:

$ ls -l ${HOME}/.pulse-cookie
1 -rw------- 1 You You 1 2016-11-24T15:58:22+0100 /home/You/.pulse-cookie
