[SOLVED] PulseAudio glitches

Hello!
When i listen to music on Spotify and another program starts playing a sound, for example when someone goes online on skype, the volume suddenly spikes and it becomes very loud.
It scares me a lot and sounds pretty bad, but I have no idea what the problem is. Has anyone experienced anything similar?
Thanks

Thanks lucke, disabling flat volumes did it. Now it crackles when i change the volume in Spotify, but it's still better than before.

[SOLVED] Font glitches in Firefox

I'm using Firefox, infinality-bundle, xf86-video-ati for a Radeon HD 7770 card, and the i3 window manager.
I have an odd problem where some letters in a web page will be displayed as junk. The glitches are uncommon. It may be 1/10 pages I visit, and one character glitch per page. If I change focus from Firefox it will correct the glitches, which is why I can't post a screen capture.
I haven't tried to reproduce in Chromium yet.
Any ideas?

Had the same problem and I solved it with creating a Xorg config file for the Radeon graphics card. The problem appears to be in the EXAPixmaps option, turning it off solved my problem. Paste the following text into a file named /etc/X11/xorg.conf.d/20-radeon.conf as root, using your favorite text editor:
Section "Device"
Identifier "Radeon"
Driver "radeon"
Option "AccelMethod" "EXA" #valid options are XAA, EXA and Glamor. EXA is the default.
Option "EnablePageFlip" "on" #supported on all R/RV/RS4xx and older hardware and set off by default
Option "EXAVSync" "on" #default is off, otherwise on. Only works if EXA activated
Option "EXAPixmaps" "off" #when on icreases 2D performance, but may also cause artifacts on some old cards. Only works if EXA activated
Option "ColorTiling" "on" #enabled by default on RV300 and later radeon cards.
Option "AccelDFS" "on" #default is off, read the radeon manpage for more information
Option "RenderAccel" "on" #enabled by default on all radeon hardware
EndSection
Afterwards, exit i3 and make sure you exit from the Xorg server and end up in the shell command line, then start i3 (startx). Or log out and log in using your display manager (lightdm etc.) The problem should be solved.

["SOLVED"] PulseAudio - some applications won't output sound sometimes

So, I have KDE 4 and PulseAudio installed, with VLC as Phonon's backend software.
After startup, I often find that Skype won't output sound at all for seemingly random periods of time. This also often happens (sometimes simultaneously, but not necessarily) to Chromium. Pavucontrol and the KDE audio mixer, don't show anything useful at all in terms of the output of Skype and Chromium, and messing with master output in Pavucontrol doesn't affect anything.
After a completely random period of time (usually a very long period of time), these applications start outputting sound again. It's very frustrating, and restarting the applications doesn't help whatsoever. While these two applications are affected, all other applications output sound perfectly.
I don't even know. I've searched, but I haven't found any similar problems documented elsewhere. Any advice?
EDIT: Solved, for now.

I fixed it (for now, at least!)
I ran the below command:
$ cat /proc/asound/cards
0 [U0x46d0x804 ]: USB-Audio - USB Device 0x46d:0x804
USB Device 0x46d:0x804 at usb-0000:00:1a.0-1.2, high speed
1 [MID ]: HDA-Intel - HDA Intel MID
HDA Intel MID at 0xf9ff8000 irq 47
2 [NVidia ]: HDA-Intel - HDA NVidia
HDA NVidia at 0xfbd7c000 irq 17
Basically, my USB webcam, which also acts as a microphone, was being treated as my default sound card. I changed this by creating a file in /etc/modprobe.d with the following:
options snd-hda-intel index=0
Which set my real sound card as default:
$ cat /proc/asound/cards
0 [MID ]: HDA-Intel - HDA Intel MID
HDA Intel MID at 0xf9ff8000 irq 47
1 [NVidia ]: HDA-Intel - HDA NVidia
HDA NVidia at 0xfbd7c000 irq 17
2 [U0x46d0x804 ]: USB-Audio - USB Device 0x46d:0x804
USB Device 0x46d:0x804 at usb-0000:00:1a.0-1.2, high speed
The problem isn't ENTIRELY fixed. Skype's still being a bit buggy, but at least Chromium is now playing sound, including in Flash media. Strangely enough, after playing a Flash video (e.g. on YouTube), Skype's sound seems to fix itself if it's defunct.

Is there a patch or a download that I can install to solve a glitch with Photoshop CS5?

My version of CS5 keeps glitching out on me... Is there a download that I can install that might fix this issue?
Thank you for any help you can give me!
I am running CS5 on a 2012 iMac with 8GB of RAM and 750GB of free Hard Drive space.

By the screenshot, it looks like you are running Yosemite. Be sure you have updated to 10.01
Yosemite upgrades have been known to damage CS5 installs and re-installs have been recommended.
I would go with Uninstall/Clean Use the CC Cleaner Tool to solve installation problems | CC, CS3-CS6/Reinstall as well as Disk Utility permissions repair all from an Administrator account.
Latest ACR is 6.7 and latest CS5 is 12.0.4 found here Adobe - Photoshop : For Macintosh
See if you are updated first. Does that Adobe symbol and 1 in the menu contain a update?

Does anyone have an idea how to solve this glitch in iCal synchronizing?

I have switched to iCoud from Mobile Me before the June, 2012 cut off date. Now I have a problem with synchronizing all my calendars in my iPhone with MacBook pro. When I go to iTunes info, and select calendars, there is no recognition of all my calendars to indicate which ones I want to synchronize . The choice of all calendars does not work. There is only one calendar showing on my Mac,and reflecting data for only a few months. On the other hand, in iCloud all my calendar show, as I had it originally with Mobile Me. On my Mac iCal only has one calendar. I travel between time zones very often, and I am between the USA and Canada for months at a time. Anyone have any suggestions as to what I need to do to synchronize calendars and make sure travel is not an issue, and without a glitch?

Thanks Roger Wilmut1 for your reply. I have Mac OSX 10.7 Lion and iOS5 . And since my question I have solved my own problem by going to System Preferences and Mail, Contacts, Calendars. I added my email addresses, including iCloud, merged the data for contacts etc. And found the missing link I needed to connect iCloud to my iPhone, and Mac calendars and more. Its now perfect.

[SOLV]PulseAudio - Simultaneous Output works until I close pavucontrol

Hello,
I'm having a odd issue....
I just installed PulseAudio on my machine (Avoided it for so long, still prefer just plain ALSA) and I'm using a ALSA backend. I installed it for the need to simultaneously output my system audio to my headphones and my speakers at the same time. Everything seems to be all right except for when I play Minecraft or WoW... Those are the two things I notice it with most. Haven't tried anything else. But, unless pavucontrol is running minimized in the background, or just open in general... Simultaneous output is VERY choppy on those apps. Switching back to a single output works just fine. But I'd very much rather use the simultaneous output...
I've been searching for the better part of yesterday to figure out why having pavucontrol open in the background would truly make a difference. I was hoping you guys over here that may have some PulseAudio experience to give me a helping hand.
I'm not exactly sure what configs to post... but here's my daemon.conf. I can post anything needed.
Any support would be appreciated.
Thanks,
Matt

Looking further into the issue this morning... It seems to be a problem with the timer based scheduler...
I disabled the scheduler using tsched=0 and now those apps work fine, except for the helicopter-like noise that it's producing now.
Any ideas how to fix that?

[SOLVED] PulseAudio with Flash Issues

Hey everyone! It's my first time posting on the Arch Linux forums and I'm excited to be a part of the community I made the switch from Ubuntu after becoming frustrated with the way things were heading (I will spare you from my rant). Installation was a bit more involved than I expected but it was a rewarding experience and I had a lot of fun setting everything up; and I am pleased with the results. I have one last issue that I wasn't able to solve by using the excellent wiki... I have set up PulseAudio and it seems to not like it when I have Rhythmbox open and Chromium running a flash video at the same time. PulseAudio stops playing audio when I have a song playing on Rhythmbox and I pause it to watch a flash video (youtube, colbertnation.com, etc). The result is no audio being played from the flash video and if I resume playback from Rhythmbox, no audio is played. The only ways I can get audio to work again is by closing all applications that play audio (Chromium, Rhythmbox, etc), restarting PulseAudio by running "killall pulseaudio && pulseaudio" (I'm not sure if this is the proper way to do this) and then playing and then opening an audio file from the file browser, or rebooting the computer. I have looked through the wiki and the forums and I was not able to find anything that would help solve this problem. Any assistance would be greatly appreciated

Yes I did boast.
Okay so I looked around the forums a bit and tried blacklisting snd_pcm_oss in rc.conf, but I did not have any success. It seems to me that is not a chromium problem but a flashplugin problem... I haven't had much time to try the other suggestions in different threads, but I will post again when I do. Thanks for the help

[SOLVED] PulseAudio wrong output balance at startup

Hello,
I'm using GNOME 3.2 with PulseAudio. PulseAudio sets my audio output balance to 90% right channel each time. restarting it does not help.
Any ideas?
I'll be happy to supply any logs needed if you point me to them. I've made no changes to any of the files at /etc/pulse.

And if I add
load-module module-equalizer-sink
in $HOME/.pulse/default.pa PulseAudio fails to start completely. I tried this on Chakra too and the exactly same happened. PulseAudio was compiled without support for qpaeq in both Kubuntu and Pardus if I'm not mistaken so I couldn't try it there. How should I proceed?

[SOLVED] PulseAudio does not start at login

I am not sure what happened to my config, but pulseaudio no longer starts at login under Gnome. Attempting to start from a terminal using
$ pulseaudio --start
fails with:
N: [pulseaudio] main.c: User-configured server at localhost, refusing to start/autospawn.
I followed the instructions on the PulseAudio ArchWiki page under "Daemon startup failed" without success. Interestingly, pulseaudio will work with
$ pulseaudio -D
I pasted the output from
$ pulseaudio -vvvv
here -> http://pastebin.com/zJYvY1FS
Any help would be greatly appreciated.

[solved] Pulseaudio, multiple users, audio group?

Hello!
I'm trying to get pulseaudio working for multiple users. According to the pulseaudio documentation, no user should be in the audio group which should theoretically make it work. I think I've also seen that information in a file distributed with the official archlinux package somewhere... But without users in that group, I'm not getting any sound at all.
$ ls -l /dev/snd
total 0

That should - according to pusleaudio docu - mean, that HAL and/or polkit will be handling user switching & stuff but it can be overridden by the audio group...? Well it does not seem to be working that way.
So... where do I start? Can't find any relevant information... everything on the subject seems to be either obsolete or just not working...
Thanks!

I log into a tty and let xfce handle the rest. Which means the first user's X gets started by startxfce4, the second user by xinit + xfce4-session (because I don't know how to make startxfce4 use another display).
I thought those two should handle everything correctly? I took a look at the sources a while back - looked pretty complicated to me: the scripts were checking for the status of needed stuff + trying to launch everything correctly.
But I'll try it manually again next time I get to it to make sure, that ck-launch-stuff is really handled correctly. Thanks for the hint!

[solved] Pulseaudio doesn't detect sound card after system update

Before a recent system update I had pulseaudio working flawlessly, but after doing a recent system update with pacman -Syu,
pulseaudio no longer sees my sound card and only displays the Dummy audio device. Among the packages updated that I can
remember off the top of my head are the Linux keneral, udev, kmod, instead of trying to roll back my system I figured I would try
to fix the issue. The only thing suggested in the Pulseaudio wiki is that a asound.conf directory is overriding the /etc/asound.conf
file which is not the case on my system.
Looking at the output from lsmod I can see where the kernel modules for the sound card is getting loaded
snd_hda_intel 23375 0
snd_hda_codec 89160 3 snd_hda_intel,snd_hda_codec_realtek,snd_hda_codec_hdmi
snd_hwdep 6389 1 snd_hda_codec
snd_pcm 74780 3 snd_hda_codec,snd_hda_intel,snd_hda_codec_hdmi
snd_page_alloc 7153 2 snd_pcm,snd_hda_intel
snd_timer 19544 1 snd_pcm
and looking at the output from the ps command I can see that pulseaudio is getting started

This behavior is confusing to me, and if someone knows what is going on and how to fix it I really want to get sound with pulseaudio working and have sound again.

[SOLVED] PulseAudio doesn't detect HDA Intel, only HDA NVidia

Hi,
I get sound only through my monitor (DP - HDA Nvidia), my external speakers or headphones (HDA Intel) are not recognized by PulseAudio. Both worked in the past, I don't know what broke it.

but in pacmd "list-cards" shows only NVidia...
I do not have ~/.asound.conf, but I do have /etc/asound.conf (I never changed this):
# Use PulseAudio by default
pcm.!default {
type pulse
fallback "sysdefault"
hint {
show on
description "Default ALSA Output (currently PulseAudio Sound Server)"
ctl.!default {
type pulse
fallback "sysdefault"
# vim:set ft=alsaconf:
Also, when I do "pulseaudio --kill" it seems to restart automatically and journalctl -f shows "[pulseaudio] pid.c: Daemon already running."...
If you need any more info on this, I'll provide it as soon as possible...
Thanks!

Here, I dug up an old file I have kicking around.
Put it in /etc/modprobe.d/alsa.conf
Name it anything you want instead of "alsa.conf" as long as the file name ends in ".conf"
options snd_hda_intel enable=1,0 vid=8086,10de pid=3b56,0bea
options snd_hda_intel index=0 vid=8086 pid=3b56
The VID and PID numbers are from my hardware. You will have to replace them from your hardware. Do:
lspci -nn | grep -i audio
And you will see both your on-board and nVidia audio devices. Look for [xxxx:xxxx] in the listing. The first xxxx is your VID - vendor, and the second xxxx is your PID - product/part.
In the "enable=1,0" line put the two VID's first with you on-board being the first VID and then put your two PID's with your on-board being the first PID. Then in the "index=0" line put your on-board VID and PID.
This will disable the nVidia audio and just enable your on-board audio. It will explicitly set your on-board audio to be the first audio device on your system. This will fix a race condition.
Remember, you must put in the appropriate VID and PID's for your specific hardware.
PulseAudio builds on top of ALSA so you are configuring your ALSA devices at a lower level before Pulse starts and when Pulse starts it adds its layer on top of that.
Another assumption is that both audio devices are using snd_hda_intel which is a pretty safe assumption. Use "lsmod" to confirm this.

Pulseaudio glitching on mute

When I press the mute button on my keyboard, there is a painfully loud burst of static. I'm using the optical output, so it's not related to some crappy internal soundcard noise. I've also added "load-module module-udev-detect tsched=0" to my /etc/pulse/default.pa file, based on the wiki: https://wiki.archlinux.org/index.php/Pu … _crackling
Any suggestions?
Thanks

Is this only pulseaudio related or does also happen with playing sound through alsa directly? If yes, then look into alsa drivers for your card and/or external hardware issues. If no, look what command you are using when pressing mute key. Run it in a terminal, maybe some error shows up. Maybe pulseaudio (or something along the signal path) does not wait for end of buffer and quits stream abruptly.
