Pulseaudio no sound

Followed the wiki and started daemon, used the fuser commands to check that nothing was using sound first and restarted daemon after closing all apps but no sound.
Here is my /etc/asound.conf:
# Use Pulseaudio by default
pcm.pulse {
type pulse
ctl.pulse {
type pulse
# 6 channel dmix:
pcm.dmix6 {
type dmix
ipc_key 1024

slave.channels 2
ttable.0.0 1
ttable.0.1 1
pcm.headset {
type bluetooth
profile "voice"
ctl.headset {
type bluetooth
profile "voice"
ctl.equal {
type equal;
#pcm.plugequal {
# type equal;
# Modify the line below if you don't
# want to use sound card 0.
#slave.pcm "plughw:0,0";
#by default we want to play from more sources at time:
# slave.pcm "plug:dmix6";
#pcm.equal {
# Or if you want the equalizer to be your
# default soundcard uncomment the following
# line and comment the above line.
#pcm.!default {
# type plug;
# slave.pcm plugequal;
#------------------------end of working file
So my setup works like this: I use plug:dmix6 for anything that is 5.1, while default upmixes stereo to all speakers for anything else (music, 2channel video, youtube, etc.). It all works great and has for a long time, but now I started using XBMC and I need to be able to switch between using dmix6 for movies/shows, and default for Music.
I have tried various video/audio files with mplayer using -ao alsa:device=pulse but get no sound.
Here is end of /var/log/messages.log if it helps:

Pavucontrol/Pulseaudio hangs sound playback

Hello everyone
I've posted on this before, and the bug went away, but now it's back and I just wish it'd go away permanently. For reasons I can't explain, trying to control the volume with pavucontrol (or, it seems, any volume control that interacts with pulseaudio) suspends sound playback. And then pavucontrol crashes with a callback timeout failure error.
I've followed all the various guides on setting up Pulseaudio. I've experimented with setting sinks, with setting sound outputs, everything. But time and again the pavucontrol applet brings the sound to a halt. As far as I know I've installed everything that might be needed. I used to like Pulseaudio, the whole control-volume-of-individual-streams is great. But it just doesn't work. And yet it's one of those features, which once you get used to it, is really hard to live without.
How can I fix this once and for all?
EDIT: Reading /var/log/errors.log I've noticed that Pulseaudio is failing to set hardware parameters with a connection timeout.

Have you tried setting the pulse volume from alsa (amixer)? You should really bring this to the pulse mailing list, since this sort of bug is probably hardware/driver level and not very simple to debug.

BASICS - PulseAudio - No Sound

Hello!
I have a fresh Arch installation and everything works fine, but I lost my sound.
That's right, it worked at first but now it doesn't. Didn't change anything regarding sound packages, only had a reboot inbetween.
pavucontrol shows me all my devices (I have an USB DAC in use) and the mixer is unmuted.
The volume meters/bars are also acting when sound is played back, but it just won't reach my headphones, it's total silence.
I don't know where to look anymore but will provide any information needed to solve this.
Really want to keep using Arch again.
Cheers!

I'm back. My sound doesn't work anymore.
It's not Arch specific though as a fresh installation of Lubuntu has the exact same problem.
I can play an audio file with
aplay -D plughw:1,0 /usr/share/sounds/alsa/Front_Center.wav
and I hear distorted crap.
Replugging the USB port doesn't help anymore, switching USB port doesn't help either.
It is something related to alsa (I GUESS!) because Lubuntu has the same problem withouth an installed pulseaudio package.
Can anybody help me out fix this?

[Pulseaudio] Pop sound when the first stream starts, auto-suspend?

Hi,
I've been having a popping sound issues whenever a Pulseaudio sink was opened. At first I thought it had a link with the power saving settings of snd_hda_intel, so I changed those two settings:
power_save setting = 0
power_save_controller = N
Sadly, it doesn't change anything.
I also tried to disable auto-mute in alsamixer. It didn't work.
Then, I tried to investigate on pulseaudio's side, and figured the sinks are disabled when they are idle, so I commented out this statement in /etc/pulse/default.pa:
### Automatically suspend sinks/sources that become idle for too long
#load-module module-suspend-on-idle
However, if I do that, the device will still be suspended when the last stream ends, but won't come back to life except if I select the device again in pavucontrol while a sound stream is running (super weird).
Any leads? I'm a bit desperate...
EDIT: I'm experiencing what's been described here: Red Hat - Bug #520403 - but the solution they proposed does not work for me. I also followed the guide for ALSA Setup on the wiki, and read the section talking about Popping Noises, but nothing works for me, I un-muted the Line-In too. FYI, my audio codec is a Realtek ALC892.
EDIT 2: Noticed it does the same thing when I mute the volume.
Thanks!
Gabriel

Right, an array of unsigned integers to be exact. You would have to look at the code, either in your sources or here and here. They may have changed somewhat, but I doubt any drastic changes. First link is to linux 3.14 version. At least I assume it gets passed on directly, if that really is the case, I do not know. Just try it, hardware damage risk is minimal.
Looking at the mask, I think it takes up to 31 samples. So try with 1, 2, 4, 8, 16, 24. I may be very well wrong about this.
Since I already have 0 and 1 in the 'trial matrix' I'll add 24 only. Adding the combinations with 2, 4, 8, 16, 24 is too much for me

On most keyboard layouts (also on the Polish programmer one) hyphen is one key one keystroke, where underscore is two key one keystroke, therefore more error prone and less efficient.
Wow, I didn't know that! What do you know! Linux being bitchy even about capital letters made me think it would be even more bitchy about '_' vs '-'.

With Pulseaudio, no sound with other apps when jack is running

I need to be able to run other sound apps with Jack running (and, ideally, be able to route sound from those apps into Ardour via Jack). So I installed PulseAudio, along with pulseaudio-alsa, and blacklisted the snd_pcm_oss module as per the Arch wiki. At that point I logged out and back in and I still had sound in all my apps. I then set up pulseaudio over jack as per the Arch wiki instructions here:
https://wiki.archlinux.org/index.php/Pu … rough_JACK
including the scripts for qjackctl. I now have sound only in my apps that use Jack; Ardour, for instance. Can anyone help? I'm using KDE 4.6 with the Phonon-VLC backend for sound.

Do some debugging first, please. The wiki instructions are really quite hackish (but there's no real good way to automate this as of now).
Kill pulseaudio, start jack (till here you're working fine I see), restart pulseaudio, try and load the jack modules and check qjackctl or pavucontrol to see if they're connected. If not, find the error logs and google them. Then come back here and ask more.

Pulseaudio delayed sound issues with simultaneous output

I've got Pulseaudio set up to send simulataneous output to analog speakers and HDMI monitor-internal speakers. However, frequently when no audio has been playing for a while, when I do something involving audio, the simulataneous output is out of sync (one of the two output is receiving delayed signal) and so it sounds odd, echo-y, and awful. I usually have to kill pulseaudio and restart to get it back working.
It's not always been like this; the issue seemed to have started a couple of months ago.
Any suggestions on a fix?

PulseAudio stops sounding when I switch to other display (Ctrl+Alt+F1)

Hello.
When I am playing any sound and I switch to a display (Ctrl+Alt+F1, Ctrl+Alt+F2...) where I have not loged in or a am not loged with my default user account, the sound stops, and when I switch back, I continues sounding.
Anyone have an idea of what could be causing this?
Thanks.

Thanks for the reply.
Is there a way to change that behavior?
Edit: After killing console-kit-daemon, sound works on all displays, but I think that it is not the best solution.

No TV sound - Problem with Pulseaudio and Gnome

Hi Community!
Since January 2013 I got big problems with the sound of my tvcard. The card is a Sundtek Media TV Pro. But after all the problems have nothing to to with the card itself!
So far I found out, that the problem is with Pulseaudio.
- Sound works under Windows on same PC.
- Sound don't work under Arch - not with tvtime, not with vlc, etc.
- Problem occurs even on a new installed system with the Arch-2013-02-01 install medium.
cat /etc/mediasrv.log
[1033] Pulseaudio connect reported an error (6 - Connection refused)
[1033] select error() in audio processor (can be caused because of pulseaudio) (Interrupted system call)
After setting up a new Arch installation with just xorg-server, gnome, tvtime and the sundtek driver from AUR I run journalctl -b:
Feb 10 16:25:15 hightower pulseaudio[636]: [pulseaudio] pid.c:
Daemon already running.
With sudo journalctl | grep 'Feb 10 16:2' I get the following output:

So, if I understand right, pulseaudio is alreade started by the rtkit-daemon and gnome couldn't start it again.
At https://bugs.archlinux.org/task/30926 I found a hint concerning /etc/xdg/autostart/pulseaudio.desktop and /etc/xdg/autostart/pulseaudio-kde.desktop.
After removing them from /etc/xdg/autostart and running journalctl -b there are no more errors.
With sudo journalctl | grep 'pulseaudio' I get:
sudo journalctl | grep 'Feb 10 17:4' | grep 'pulse*'
Feb 10 17:41:42 hightower rtkit-daemon[485]: Successfully made thread 484 of process 484 (/usr/bin/pulseaudio) owned by '120' high priority at nice level -11.

In my opinion all looks ok! I also checked the channels with the alsamixer and it looks good, too.
So I ran vlc v4l2://:dev=/dev/video0:width=720:height=576:tuner-frequency=510750:adev=/dev/null:standard=255 - but still no sound.
With cat /var/log/mediasrv.log I checked the drivers logfile:

I started tvtime again. This time I ran rm -rf ~/.config/pulse/ and killall pulseaudio to kill the Pulseaudio server. I instantly got a loud noise out of my speakers.
I closed tvtime and re-opened it. And there it was: TV SOUND OUT OF MY SPEAKERS!
But now, when I run pavucontrol I get:
Connection to PulseAudio failed. Automatic retry in 5s.
In this cas this is likely because PULSE_SERVER in the Environment/X11 root Windows Properties or default-server in client.conf is misconfigured.
This situation can also arrise when PulseAudio crashed and left stale details in the X11 Root Windows.
If this is the case, then PuseAudio should autospawn again, or if this is not configured you sould run start-pulseaudio-x11 manually.
I got the information from Sundtek, that Pulseaudio should not be started as system service. Instead, every user should have an own Pulseaudio daemon and that PA was concepted this way. But they don't know how it is implemented in ArchLinux.
I also don't know it exactly. So the question to all you ArchLinu pro's:
How is PA implemented in Arch? And how can I sustainable solve my problem?
Thank you for your time and help!

There is just one more thing I found out.
After logging into Gnome and running ps aux | grep pulse I get:
rebel 727 0.7 0.2 444316 10288 ? S<l 03:02 0:00 /usr/bin/pulseaudio --start --log-target=syslog

rebel 843 0.0 0.0 17396 1184 pts/0 D+ 03:03 0:00 grep pulse
To get the sound to work I run:
rm -rf .config/pulse/
killall pulseaudio
killall -9 pulseaudio
I again run ps aux | grep pulse

rebel 4046 0.0 0.0 19456 1216 pts/0 R+ 03:07 0:00 grep pulse
I can recognize that the STATs have changed. Maybe this can help to solve the problem?

[Solved] Sound with ALSA and PulseAudio at the same time?

Hi, I am using arch linux to play Counter Strike on.
While it works fine and all, I just don't get any sound in CS because I am using Mangler, which only seems to work with my microphone if I use PulseAudio.
I hope this is a rather simple issue, basicly, I just want to enable sound in PulseAudio and ALSA at the same time, is this possible?

I have read that PulseAudio decreases sound quality, and therefore I would not like to use this as a systemwide driver, but rather only where it is needed.
Please correct me if I am wrong
Edit:
Ok, sound quality isn't noticeably worse, so this will do. HOWEVER, while I am in Counter Strike my sound is delayed by ~1 second, and it is therefore useless, any thoughts on that matter?
Edit again .. Solved this time:
I set my ALSA plugin in winecfg to "Hardware Acceleration: Emulation" - that seemed to do the trick.

No Sound in ALSA & Pulseaudio despite configuring

Right.
So, I installed ALSA, and fully followed the wiki's instructions to no avail. On a previous install on another computer, I was able to fix the problem by installing Pulseaudio, and so I did it again on my current comp. I got sound on this computer on a singular occasion after the Pulseaudio install, but now sound is gone again. Any idea why?
I am using compiz-standalone, and in my ~/.start-fusion.sh, I already have
pulseaudio --start
in it.
However, when I run pacmd list, it still states that there is no Pulseaudio daemon running. I have to start it manually in the end, and still, sound doesn't work.
I also noticed that when executing
$ fuser -v /dev/snd/*
$ fuser -v /dev/dsp
/dev/dsp does not exist.
asound.conf is already to let pulseaudio be the default device, and everything in alsamixer is unmuted. I have also installed alsa-plugins, so there, really, should be no reason why pulseaudio, and sound in general doesn't work.

I'm not sure what volume control/mixer you are using but I installed pulse audio yesterday along with gnome-media-pulseaudio and through gnome's applet I was able to change my hardware's profile and manage to get sound and volume controls back hope it helps (i'm running compiz stand alone as well but have Gnome DE too)

Can not get output from Objective DAC without Pulseaudio [SOLVED]

I have owned the ObjectiveDAC/O2 Amp combo for a couple of months now. Unfortunately I was unable to get the device to function properly without pulseaudio installed. When trying to configure it on a pure alsa system, I can set it as the default control card in alsamixer. The issue is that when I set it as the default pcm device, it fails to work. I can select the device in pulseaudio fine, and my system recognizes the device in alsa, however I cannot, for some reason, actually use the device. It seems that pulseaudio butchers sound quality, and I would greatly appreciate any help being able to get my device working without it. I can't believe that any sane individual would actually make part of the audio stack downmix audio by default.
It was just a lack of understanding of Alsa's config syntax. I do apologize for taking up space on the forums. I now have Alsa running with my DAC just fine.

Yeah that's what I meant. Try to burn a new cd at a slower speed. When the new one is done create a hashsum of the new burn and compare it to the iso you used to burn it with. I only say this because a few times in the past when I had sr0 errors while booting live cds it was because the disk was messed up and I had to burn it again.

[SOLVED] LXDE: no sound in thunderbird

Just cleaned up my laptop by removing KDE, Gnome, and every other DE/WM I've managed to collect over the years. Now I'm running LXDE, and am so far delighted with how far it's come since the last time I tried it (several years ago).
Anyway, I've got everything working just how I want it, except for Thunderbird/Lightning notification sounds. They just don't play. I installed pulseaudio and sound from other GTK apps (pidgin) works just fine, as does youtube, etc.
I've read a few TBird bug reports that hinted it relied of ESD for sound. I only found ESD in AUR, though:
aur/esound 0.2.41-3 (285)
Enlightened Sound Daemon
Previously I was using KDE4 and Thunderbird sounds worked, I assume via ARTS.
Anyone have any idea?

that problem is likely a bug in PULSEAUDIO, as pulseaudio is SUPPOSED to be a drop-in replacement for ESD.
In KDE4 / QT Phonon takes care of the multimedia, and normally apps don't goto pulseaudio directly.
Output is send to phonon, which then sends it to the chosen output device, which CAN be pulseaudio.

[SOLVED] Software mixing on ALSA+USB sound card

I have cheap chinesse USB soud card. lsusb says its "Tenx Technology, Inc. TP6911 Audio Headset"
After arch installation sound was working about 2-3 reboots. Then i googled and deleted pulseaudio, and sound randomly working or not after reboots.
After a lot of research i got /etc/asound.conf like that:
pcm.!default {
type hw
card AUDIO
ctl.!default {
type hw
card AUDIO
"AUDIO" its name of card. Checked that. And now i had sound in 80% reboots.
After research i founded that i cant play 2 sounds at same time. (And youtube writes "error occured" for 90% videos).
Tested aplay (it never works):
>aplay /usr/share/sounds/alsa/Front_Center.wav
Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono
aplay: set_params:1239: Channels count non available
Then played sound in other program and in same time launched aplay:
>aplay /usr/share/sounds/alsa/Front_Center.wav
aplay: main:722: audio open error: Device or resource busy
So that mean i need software mixing.
Googled, and installed "alsa-oss" and did some random stuff with config
pcm.!default {
type hw
card AUDIO
slave.pcm "dmix"
ctl.!default {
type hw
card AUDIO
slave.pcm "dmix"
and now youtube working. I hear it. But now aplay says:
>aplay /usr/share/skype/sounds/CallBusy.wav
ALSA lib pcm_hw.c:1743:(_snd_pcm_hw_open) Unknown field slave
aplay: main:722: audio open error: Invalid argument
He dont like "slave" thing in config, but it helps. I tested 3 times, added "slave" and rebooted and youtube works. Without "slave" it not working.
And i still cant hear 2 sounds at same time. In google ALSA says like software mixing must work without config, if not then do bugreport.
Im in arch less then 7 days, before i had experience with ubuntu server only, so configuring ALSA is hard for me.
Can somebody help me configure software mixing?
Thank you.

Okay. I surfed your URLs and ended in http://alsa.opensrc.org/Dmix
Example /etc/asound.conf from 3 and 5 works great! Thank you!
If somebody will google Tenx Technology, Inc. TP6911 Audio Headset
Use /etc/asound.conf (you need create it)
pcm.dsp0 {
type plug
slave.pcm "hw:0"
ctl.mixer0 {
type hw
card 0
or
pcm.dsp0 {
type plug
slave.pcm "dmix"
hint {
show on
description "My dmix dsp0"
ctl.mixer0 {
type hw
card 0
both works for me.
=======
Aaaaand after 2 reboots everything is broken. Both configs not helping. aoss and alsaplayer don't make any sound.
5 reboots later sound again works.
=======
Okay, i know why i need reboot.
If you have same problem - do aplay -l, if your card not first - nothing will work. You need reboot until your card is first. I tryed to do my card always first, but then mixer dont work. And for make it work on every reboot looks like you need read 18 huge books about universe creation.

Gnome3 without pulseaudio (again)

Hi all,
I always have had a particular hate for pulseaudio, a sound daemon that stands as a layer between apps and the hardware. Great idea, if it only worked! It doesn't!
Configuring and getting it to work is a real pain, as it doesn't work out-of-the box.
Gnome 3 now seems to depend on pulseaudio, which I think it's a bad decision. At least KDE let's you choose!
I was about to ditch Gnome3 - even though I was enjoying the experience - then I came accross a thread in this forum where other people have the same problems with pulseaudio. The topic is this: https://bbs.archlinux.org/viewtopic.php?id=117986 (post #9)
So I did all that. Renamed and later deleted all pulseaudio-* under /etc/xdg, launched gnome-session-properties to disable pulseaudio, deleted .desktop files under ~/.config/autostart and even then it seemed to start.
Installed alsa-utils, ran alsaconf, rebooted.. And pulseaudio was still there. Don't know what process is is invoking it, but I'm guessing it's the neat volume manager in the tray.
Finally I ran gstreamer-properties, chose ALSA instead of pulseaudio, and then....renamed pulseaudio itself mv /usr/bin/pulseaudio /usr/bin/pulseaudio.o.
Ah.............................everything was just working normally, except for the volume keys (as the neat volume manager disappeared)
So, how Can I replace the default app in the tray?
The sound definitions under System seem to be pulseaudio related and now no soundcard is shown.
Any ideas?

You can blow Pulse off your system entirely by doing pacman -Rnsdd pulseaudio. (I also got rid of pulseaudio-alsa. I don't know if you need that if you're using something other than OSS). After removing it, I unchecked/disabled all references to Pulse everywhere I could find in config utilities, and then deleted every file that had that nasty p-word in its name anywhere in ~/.
Then I had to go through this harrowing process to get sound working as one would expect it to: pacman -S oss.
I had the same issues as you, though, thanks to Pulse integration. Basically, no volume control: Volume icon does nothing, multimedia keys don't work, and there's no OSD indicator when the volume is/should be changing.
For the first problem, oh well, I removed the volume icon from the panel. I always did that, anyway, because I just use the keyboard.
For the second, I created three one-line scripts and bound them to my multimedia keys. For oss,
Volume up: ossxmix vmix0-outvol +1
Volume down: ossxmix vmix0-outvol -- -1
Mute: ossxmix vmix0-outvol 0
These are the laziest things ever. Mute just turns the volume all the way down, it can't return you to where you were. The OSS FAQ has more sophisticated script examples, if you're into that. I think the third problem (no OSD) can be resolved with scripting, too.
ALSA can be controlled via scripting with amixer: http://manpages.ubuntu.com/manpages/gut … xer.1.html
Rant time: I have no idea why the GNOME guys decided to integrate with a particular sound system. Linux sound is a total mess. Users' needs and mileage vary so greatly -- nothing works for everyone. In my personal experiences, OSS has always worked 100% out of the box with zero effort or configuration, whereas with Pulse the closest I ever got was, "I can make sound from one application, but please don't try to use two at the same time or everything will explode." I gave Pulse about 45 minutes after GNOME3 came along. Then it was like, "Why am I wrestling with this when OSS was already working with no effort?"

Multiple instances of mplayer with jack

"_R_ealtime software mixing ?!?! wtf thats awesome--actually im not a studio junkie, i just need sound on one of them"
i understand that the casual nature of my involvement with jackd suggests a less-than-appropriate level of respect and diligence for what this almighty app is capable of serving up. i just need to level audio volume on multiple instances of mplayer with software mixing (my sound card is cheap).
all my jackd configs are vanilla from the wiki as stated below. if anyone has another solution or a request for information in regard to this solution please reply. as always, thanks in advance
--here is some err... background
i have a some files that i would like to run with mplayer and a video file [with its own audio] that i would like to run concurrently. it should be possible to use jackd to let one instance of mplayer show video with no sound while permitting the audio from the other instance to play at arbitrary volume. without jack, i cannot control sound independantly since both instances seem to use the same device (PCM0). furthermore i have found that starting multiple instances of mplayer leads to weird artifacts which persist after all running instances of mplayer concurrent with artifact appearance have been closed.
so i installed jack-audio-connection-kit following the wiki verbatim. then i installed qjackctl. starting jackd as root and qjackctl with sudo allowed me to see the first instance of mplayer but not the second.
what is the difference between running mplayer through alsa and running mplayer through jack through alsa (not sure if the objects are accurately laid out there but whatever)? the wiki basically provides an out of the box solution for software mixing a bunch of inputs (i have friends who do sound professionally though not with linux and im envisioning way more complicated stuff than my humble pair of mplayers

If you run one file with '-ao null' and the other one with '-vo null' you can manipulate them independently, there's no sound mixing involved, it just allows you "to add visuals to an audio feed spontaneously". They can both be run with 'af scaletempo' to speed up / slow down etc.
Hmm, wonder if that's what the OP was looking for?
