Pulseaudio won't start --> no Sound in Flash (HTML5 works)

Pentium4User · 01-28-2018, 04:47 AM

Hello,
I have Slackware 14.2 i386 installed on my notebook. I have the 00:1b.0 Audio device: Intel Corporation 8 Series/C220 Series Chipset High Definition Audio Controller (rev 04) audio controller. On Ubuntu it worked fine. I think it was the intel_hda module.
On Slackware kmod list includes these things:
snd_hda_intel 25395 10
snd_hda_codec 96742 4 snd_hda_codec_hdmi,snd_hda_codec_idt,snd_hda_codec_generic,snd_hda_intel
snd_hda_core 45638 5 snd_hda_codec_hdmi,snd_hda_codec_idt,snd_hda_codec_generic,snd_hda_codec,snd_hda_intel
snd_pcm 79212 7 snd_hda_codec_hdmi,snd_hda_codec,snd_hda_intel,snd_hda_core

The module should be loaded.
I am logged in as root
When I try to start it with start-pulseaudio-x11 the it returns the following:
Failure: Module initialization failed

/etc/pulse/clent.conf:

; default-sink =
; default-source =
; default-server =
; default-dbus-server =

autospawn = yes
allow-autospawn-for-root = yes
; daemon-binary = /usr/bin/pulseaudio
; extra-arguments = --log-target=syslog

; cookie-file =

; enable-shm = yes
; shm-size-bytes = 0 # setting this 0 will use the system-default, usually 64 M$

auto-connect-localhost = no
auto-connect-display = no

What can I do to fix that?

Kind regards

Which desktop environment are you using?I note from the slackware pulseaudio howto it is mentioned

Quote:

Starting PulseAudio

XDG-compliant DEs will start PulseAudio automatically thanks to /etc/xdg/autostart/pulseaudio{,-kde}.desktop files.

In case you aren't using those, you can use start-pulseaudio-x11 command. Just add it to your DE/WM autostart. Plain pulseaudio --start will also work. To stop PA use pulseaudio --kill command. Be warned, that if you didn't disable autospawning, it'll respawn as soon as some application requires the sound.

So, it might be possible for you to start PA with the alternative desktop method (if compatible).

More information might be helpful. Try starting a user-instance via the CLI...

Code:

pulseaudio -k;pulseaudio --start --verbose

Any errors?

FWIW, I found this askbuntu thread
which sheds some light on where to look. PA modules are loaded according to the configuration in /etc/pulse/default.pa, and it might be that PA attempts to load some module dependent on the X-server running before it actually is. In the thread the 'module-bluetooth-discover' that was the culprit.

open pavucontrol and see if you're muted, see if it has a selection showing out put to your web page, web page has to be up and running a video, then check its drop down list to see if it has a selection for output or not. See where it says it is sending the output.

I had assumed that pulseaudio is not starting based on this comment. Maybe it actually is?

Code:

ps -ef|grep pulse
