Fedora :: PulseAudio On F13 - Large Crackling Noise In Skype
Apr 25, 2011
I have had problems with pulseaudio since F13 so the problem is not new just that I have been working since 12 AM till now 6:30 AM trying to fix it and I have failed the only thing left from what I see is a complete reinstall. When I start skype it works for 5 secs then the sound becomes corrupt and make a large crackling noise. I have reinstalled alsa and pulse atleast 10 times removed any trace of config files and still the same result. It first broke when I turned off tsched in hopes that my microphone will no longer broadcast a buzzing sound. This setting broke everything and even after I reverted it the symptoms remained the same. It's 3rd time I reinstall fedora because of pulseaudio. Until the problem can be fixed I have reverted back to ALSA.

I seem to be getting a crackling noise when switching songs in Rythmbox.
This happens with headphones and without...
Does anyone know this might be and how to fix it?

This is a weird and persistent bug that I've been having. It's persisted across multiple distros (Arch and Debian) and is currently making my computer only usable without sound. I'm beginning to think it's the hardware.
Anyway, the hardware is a Lenovo Yoga 2 Pro laptop. I'm currently running Debian 8. The crackling noise begins shortly after I log in - it happens regardless of whether the audio is muted, or whether anything is currently playing. It's a very, very loud noise - on the level of a vacuum cleaner or similar (maybe, these things are hard to estimate). It sounds sort of like a fast series of crackling pops. If I put the machine to sleep with the power button the crackling will go away for a little bit after I resume - I haven't timed it or anything but I imagine that it takes 30 seconds to start up again (after the computer has woken from sleep).
I can completely eliminate the problem by doing the following:
Code: Select allblacklist snd_hda_codec_hdmi
blacklist snd_hda_intel
blacklist soundcore
blacklist snd_hda_codec_realtek
blacklist snd_hda_codec_generic
[Code] ....
But obviously, this makes the sound on the laptop not work at all. I've been listening to music with my phone, which is an ok workaround, but I'm a programmer and I'd like to be able to watch talks on youtube and so on.
lspci:
Code: Select all00:00.0 Host bridge: Intel Corporation Haswell-ULT DRAM Controller (rev 0b)
00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 0b)
00:03.0 Audio device: Intel Corporation Haswell-ULT HD Audio Controller (rev 0b)
00:04.0 Signal processing controller: Intel Corporation Device 0a03 (rev 0b)
00:14.0 USB controller: Intel Corporation 8 Series USB xHCI HC (rev 04)
[Code] ....
It started happening on Arch after a pretty standard install (i3wm with Xorg, browser, terminal emulator, etc) and I suspected that I had misconfigured something, so I installed Debian - I know other Debian users with this laptop who have not had this issue, and so I figured the default settings would treat me better. No such luck - it started happening again on the clean Debian install. One detail - both installs (the Arch install and the Debian one) use full disk encryption (lvm on LUKS) but I can't think of how that would affect it.
My only thought is that it's some weird power saving mode issue - the soundcard isn't used for a bit, so it cycles to a lower power state, and the bad thing happens.

I have installed Skype beta 2.1 on my ubuntu 9.04, everything works except the mic. All I get is noise (SSSHHHHH) when i try to use it. moreover Looking in volume control, no matter what volume I have the mic set to initially, as soon as I initiate a call the mic volume goes all the way to zero (then initiating that crackling staticky bug) and turning it back up doesn't work as the volume slider just slides back down. and also one of the mic channels (left or right, I can't remember) comes to zero and slowly the other follows it.

I'm getting this weird noise and (sometimes) delayed audio on HDMI out on VLC. I've tried banshee, miro, ..... on FF and all of them work just right. I would settle changing VLC's sound output to ALSA, but it's also buggy as I get no audio after pausing. Restarting or reloading Pulseaudio and ALSA didn't work either.
Does anybody have a recommendation? Obviously, I'd like to stick with VLC.

I installed skype 2.1 beta and pulse audio. Just installed the packages and it worked. Surprisingly. Problem is that Skye now selects pulseaudio for microphone, out and ringer. No problem it actually set it up to my logitech headset which is by default almost right. It set it up to use my logitech microphone and headset speakers for talking, which is great. But I want to switch my ringer from headset speakers to main computer speakers. Anyone know where this can be done. Skype only lets me select pulseaudio (locla server) for all three. Yet somehow it knows to use my logitech headset for talking. But I want to direct my ringing of incoming calls to main speakers. pavucontrol does not let me do this. Anyone has an idea of how to do this? If there is a graphical application that can do this, please let me know.
Used ubuntu for years and loved it. recent bugs in flash and loggin out and others made me try debian for extra stability and security at the risc of loosing myself in the complexity of debian as it's no plug and play here. So far seems to be very similar in use to ubuntu, surprisingly. Running nvidia-xconfig seems to be the only difference. So far I have been able to figure things out to make it work, we will see how I do in the long run. Ubuntu was sure easy.

I am using 8.04, Pulseaudio, Microsoft Lifechat USB headset and Skype on a Compaq 210. Pulse works fine for everything else. One day, it just stopped working for no apparent reason (only on the Skype mic) so I uninstalled and went back to ALSA (for a few reasons) but couldn't get that working either so now back to square one. When I boot Skype, all goes well, can place a test call, no errors. But on playback of the message it's pure fuzz, basically white noise, no sign of my voice. I've twiddled with just about every volume control and toggle I can find and then some, but nothing. Another interesting thing; Pulse is now NOT working unless I input 'pulseaudio -D' in a terminal after boot. Then it seems to be okay, 'cept the mic.
Strange as the mic works perfectly and crystal clear in Sound Recorder. No probs. So:
1/ How do I replace the recorded white noise in a Skype test call with my own mellifluous tones and;
2/ Where do I put 'pulseaudio -D' (what file) so it will be read and turn pulse on at boot?
Using Skype 2.1.0.47 (I know there is a newer version, .87 I think, but that was even more problematic). Another strange thing; the newer version (.87?) worked flawlessly for months before the mic just one day died (ONLY in Skype). As explained on my last thread; wife's uni/entertainment machine and me being the house computer dude, one of the reasons we use Linux is so I am not fixing Windows problems constantly. I only go near this machine when something goes pear-shaped so that is rarely. My wife doesn't tweak with her computer AT ALL.
Sound issues on this machine have been pretty much constant and I am really sick of it. I have two desktops running ALSA and Skype flawlessly with any USB headset AND they can ring incoming calls through the external speakers and you can take the call through the headset, something that is seemingly impossible for some reason in Pulse. Despite its bells and whistles, this is a serious oversight by Pulse developers in my opinion. (Unless I'm missing something and I've have searched for hours trying to fix THAT little mystery).

Just upgraded to Lucid (32bit), pulse generally seems to work ok: I get sound out, I can see various apps connecting via the Sound Preferences dialog (audacious, flash via alsa interface, etc.), and my mic seems to work fine too.
However, when starting skype (v2.1.0.81 which defaults to pulseaudio if it's running), it isn't able to output any sound and I never see a connection appear in Sound Preferences. Don't really want to force it to use Alsa or anything like that; I'd be fine with pulse if it would just work.
I've tried installing the .deb from the skype site as well as the official ubuntu package, with the same result. Any idea why pulse seems to be working, but skype can't seem to use it properly?

I've got Karmic installed on a MacBook, and I'm trying to get Skype up and running. I've already patched the iSight firmware, so the the webcam itself works fine, but I have no microphone support. If I go to Sound Recorder, the microphone picks up my voice fine, but not Skype. In the Skype audio settings, all are set to Pulseaudio server (local), and that is the only selection available.

I recently upgraded to 11.4, but skype seems to mute all other application streams when a call is active. I can manually unmute them, but it is rather annoying especially when listening to music in the background using Amarok since everytime a new track starts it creates a new stream and is muted again.
I installed pavucontrol just to see if it had more options then kde's built in multimedia settings, but it doesn't (just has the cool how loud is the volume currently). I like the individual application (stream) volumes.

i am having a problem with skype that i wasn't having before, and afaik skype hasn't been upgraded recently, so something else presumably has changed.
because of driver issues i have to use an external usb audio interface to do voip. this interface is not connected to the pulseaudio server. i am able to connect it to jackd and it works fine for both audio in and out. however it no longer shows up in the list of sound devices available to skype. this used not to be the case. i have tried stopping and restarting skype, as well as unplugging and reattaching the interface. the interface does not show up in pulseaudio manager in the lists of devices.

Due to the fact that with pulseaudio it is impossible to change the microphone/speaker/ring devices in skype, I had to remove pulseaudio.
After that I can choose a device in skype, but the mixer does not work anymore. There is a way to have a working mixer without pulseaudio package or a way to choose audio devices in skype with pulseaudio installed?!

Does anyone notice a degradation in sound quality with skype and pulseaudio? It seems that when I use pulseaudio there are bugs in the sound quality in skype. I also notice a lag when talking to someone with the VoIP feature.

When I installed my 64 bit system of Ubuntu 10.04 the sound worked very well and I were very happy. The problem started however when I installed Skype which uses pulseaudio. As soon as I start skype (or any other application that uses pulse, HoN for example) the applications sound output or input does not work at all. If I have pulseaudio started in some way, applications that I suppose do not use it like spotify or flash player stops to produce sounds. And when I type "pulseaudio" in the terminal it gives me this:

I've tried some workarounds like adding an audio entry in the registry but it did not work. I think that the problem is related with the pulseaudio driver...

I have a Creative Labs SB X-Fi sound card and I am getting a lot of crackling & popping with it. Plus I have to kill and restart pulseaudio a lot. Does anyone know of anything that can be done to help this out? I have the latest F12 kernel and rpms installed.

I've had nothing but trouble with Pulseaudio in Fedora 14. I had managed to get rid of it in Fedora 10 with the command: su -c "yum remove alsa-plugins-pulseaudio pulseaudio" I just don't want to have to deal with Pulseaudio anymore. It does not like my sound card and gets in the way. Is there a Linux distribution that does not use Pulseaudio ?

When I installed fedora 11 I had bad sound which crackled and crashed. I followed this guide -http://forums.fedoraforum.org/showthread.php?t=225660 - which fixed my issues in videos playing on the web and in VLC. However; in the last few days sound has bugun crackling again in VLC while playing videos (web is fine). All updates have been applied and I am running 32 bit Fedora 11.
Also totem when playing video crashes, freezes, crackles etc while playing videos though playing sound files is fine with no issues. Any ideas how I might solve this and get my sound while playing videos back to how it used to be?

I just installed skype 2.1 beta 2 (the deb file) from the skype website, but the only option I see under Sound Devices -> Recording is "PulseAudio Server (local)" This doesn't work for me, as the skype test calls don't actually record anything I say. I use skype a lot and FINALLY got it working under karmic, but I needed to upgrade to lucid and now it's broken.
When I open Sound preferences and look at the Applications section, Skype shows up as recording when I run its test call... but no sound is recorded? How is it possible that my sound card picks up something recording but doesn't actually record it when I'm in skype?

My desktop becomes very quiet once windows7 is loaded.. but the fan, maybe cpu fan runs continuously in fedora 13. though it's not quite noisy, I thought I didn't install the correct drivers for the Asus h55 mb. the mb cd has a directory "isolinux", which contains a boot.cat, isolinux.bin, isolinux.cfg along with two subdirectories, data & src. but isolinux.bin is not executable.. how can I install the drivers in fedora?

I have downloaded & installed the skype beta release for linux (now ancient?) on my newly build fedora 14 (64) box.
Under fedora 12, I made this work after several hours of mucking around by installing old libraries for 32 bit code in /lib and /usr/lib - as I got an error, I found the library and put it in place. This was painful and the WRONG way to do things - I should have been using yum!
It remains a shame that the Skype release for Linux is so old, but that is life.
Can anyone list the libraries needed (prefer yum names if possible) to make this work?
I can do this again the hard way and list the results for others (should have saved for myself, but I never dreamed that a newer Skype release would take so long) , but I am sure many folks have this working already. I am surprised there is no "yum install skype---" command.

how big and widespaced the fonts on Clementine playlist are and how good they look on the appmenu (where my mouse pointer is). This is not because Clementine is QT4, I've got the same problem with Chrome, Opera etc. I've been messing with system-settings (KDE settings tool) a day before the fonts become that widespaced in order to make my KDE apps look more native on my GNOME, but I haven't touched the fonts settings there.

I am running F12 on a lenovo X61. 00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03) If my machine is quiet for a while, then suddenly needs to make a noise (eg some sort of notification event), the audio "pops" when the first sound is made. It sounds like the noise you hear in the speakers when the audio cable is connected to a live jack while the speakers are on. A static POP.
Once that initial pop is over, the audio sounds exactly like I expect it to.Then, if there is no sound for a period of about 10 seconds, I can hear the audio pop again. If I then play a sound, I will hear the initial static pop again.It's as if pulseaudio is powering up my audio system when it needs it, then powers it down when it doesn't need it any more.And, in fact, I found that something is going in in the kernel. If I look at lsmod, I can see things changing.I did an lsmod with the sound "on", then waited for it to pop off, then did it again and noticed these diffs:
< snd_hda_intel 25080 3
---
> snd_hda_intel 25080 2
34c34
[code].....
Now I also have F12 running on a desktop machine that uses an nVidia chipset. I have no audio pops on that system. I noticed that there are similar changes in lsmod on that system, though.
