Fedora :: Audio Output Distorted In F15
Jun 4, 2011
I have a problem with the audio output in Fedora 15. It seems 'dirty' to me, like with a lot of distortion. I use for the output a nice USB DAC that seems to run very good with Ubuntu and Windows, strangely with Fedora isn't the same. I say strangely because the sound pipeline must be very similar to that of Ubuntu, no? Kernel, ALSA, Pulseaudio and so on. How could I improve mine audio output? Tried with Flash videos and Audacious audio player. Lowering audio output (like to 50%) greatly improve audio quality! Why is permitted to the system to go over and distort?

I am running Karmic (9.10) on an MSI U120 Wind. I dislike netbook-remix but that is beside the point.
Last night I made the biggest mistake of my life which is causing a loss of still counting hours. I decided to do an update, due to having enough bandwidth, and security updates to download.
So it finished, and I went to sleep.
This morning I went to plug in my speakers to the audio jack so I can listen to music loud, and it was all distorted. I changed al 8 or 9 volume controls and nothing. I unplugged the wire from the audio jack, and the sound is perfect on my netbook's speakers.
I have tried different wires, speakers, editing config files, removing and purging related packages, and nothing works...
I have been google-ing for hours and everyone seems to have the same problem, but all of the supposed fixes do not work for me...
Here is a pastebin of my Alsa info : [URL]
I fear switching back to winblowz..

I've gone through the process of installing and setting up OpenSuse, which has been fairly streamlined.
The only problem I am having is with my Soundcard the audio coming out of it is highly digitally distorted unless I set it to 100% or 50% in the sound preferences section. Once this is done, the audio quality is still fairly awful, but doesn't sound like my guitar's fuzz box!
I'm assuming this is some sort of drivers issue and I have a few options in my yast audio configuration that I'm unsure what to do with.
They are as follows:
Now, these options are all able to be given a numerical value, first question, what do they stand for and what does the value do?
And second question, does anyone know what a semaphore is in relation to audio codecs? I have worked with audio for years and never some across this termanology?

Running 10.10 and win 7 on my HP dv6-2150us laptop and I'm having a few issues.
First how do I get HDMI audio output to my TV? I think I have just a integrated Intel graphics card. It works fine in windows but I can't seem to get it to work in Ubuntu. I tried searching but couldn't find anything pertaining to this issue.

I finally got audio working on my ubuntu 9.10 desktop... now I am having sound issues watching movies from a network share.The sound device continually randomly changes to "dummy output device" and then there is no sound output. The sound icon dissapears on the toolbar. To get it back and audio to start working I have to $sudo alsa force-reloadIt seems to happen everytime there is a network delay, the movie will stop for a second and then when it plays the sound is gone

Say I have 2 speakers connected to 2 different sound cards. Under Windows, is it possible to have some sort of virtual device that would forward an audio stream to both sound cards? If this can't be easily done under Windows, a solution for Linux is also fine. lternatively, if the 2 speakers are connected to different channels of a sound card, is there any vendor-independent way to duplicate audio to both channels?

i'm running fedora 12 on a dell dimension 4600. audio seems to work reasonably well for things like flash animation but i cannot for the life of me figure out how to route line-in audio through the system for output to my external speakers. on the sound preferences application on the gnome desktop: if i select the hardware tab and analog stereo input is selected, then i go to the input tab and have analog line-in selected, i see the v-u meter above moving around as though there is actually an input. [list]
but, i hear no sound. the output tab shows "dummy output" with no other choices. to get audio working for videos and other flash sites, i have to change to hardware->analog surround 5.0 output. such documentation as i have been able to find doesn't seem to describe my setup well, and in any case, i find all this fidgeting with hardware configurations an immense step back from the old alsa software. if this is going to be the future of linux audio, can i say, please, no?

I have installed Fedora 13 on my laptop, but there is something wrong with the sound。It just comes from both the computer and the headphone. I have installed alsa, you can see as follows:
[PDS@localhost ~]$ rpm -qa | grep alsa

alsa-driver-1.0.23-84.fc13.i686

This started today in my session: no audio output. In sound preferences, hardware, in Profile, the options are now Off and Analog mono input. In Output tab, I see Dummy output stereo as the device. Nothing is muted.

I'm running PyMOL version 1.2r2 on Fedora 12 with python2.6.
Only for a second or two will molecular models display correctly in the PyMOL viewer, and then the image becomes distorted. As I rotate the model, it displays correctly, but then almost immediately after I stop moving the model, it becomes distorted again.
The attached images show the display before and after the distortion.
This is some of the information that the PyMol program prints as it loads.

So I have a DAC/Headphone Amplifier which plugs in through USB. Through the system settings I'm able to set it as the preferred audio output option. This makes all the windows manager sounds come through the headphones, but all the applications still come through the laptop speakers; i guess they are completely independent of the system settings. I have to set each application's output preferences separately, and some software (like Firefox) doesn't have any output preferences. So is there a way toirect the audio output of all applications to all come through the USB DAC

I am running latest fc11. the startup sound (desktop-login.ogg) always plays distorted. it plays a chord or two, slight pause, plays another chord, etc.. skips about as much as it plays. i found if i run canberra-gtk-play with the ogg file from a terminal, it plays fine. i changed it to play /usr/share/sounds/startup3.wav, but it also plays distorted during startup. plays fine from a terminal or thru natilus. i have installed the pulse-audio through the "perfect" guide.

New build to F12. Sound was fine in F11. Now, massive distortion. I have tried every possible permutation of settings. With the main volume control in the top taskbar, there are two positions of level setting where the audio drops to a normal level and sounds OK but any application changing the level or starting to use the Pulseaudio changes the level and its loud and massively distorted again.
In the Pulseaudio manager->sink->alsaoutput.pci-0000-00-11.5.analog-stereo -> properties-> show volume meter, the audio is always maxed out in level. I have tried everything, its unworkable right now. Its possible to start alsamixer from terminal and adjust settings for good audio but any future change reverts to distortion. All changes in Pulseaudio Dev mgr or vol control etc change the audio as they should but do not affect the problem.

I have a StarTech USB audio adapter which I have been unable to get output from in Suse. Pavucontrol allows me to adjust the output to this device, and even shows some signal when playing media. However, no output makes it to the headset/speaker jack of the USB device. There does not appear to be any issues with playing media to the internal sound card & speakers of the computer. I booted up a Live Ubuntu disk, the device was recognized, and output made it with no problem. This leads me to discount a hardware problem. I'm running Suse 11.4 on a Lenovo Thinkpad T420s.

I just got rid of pulseaudio because it breaks in so many different situations. I've switched to Alsa, and all of my sound is working except in mpd. It seems like I have to set audio_output in /etc/mpd.conf. Here is my config file:
audio_output {
type "alsa"
driver "pcm"
name "whatever"
}
When I start mpd, this is what happens:
$ sudo mpd --no-daemon --stdout --verbose
playlist: play 1:"Party Playlist/01 Block Rockin' Beats.mp3"
decoder: audio_format=44100:24:2, seekable=true
alsa: default period_time = buffer_time/4 = 371519/4 = 92879
alsa: buffer_size=16384 period_size=4096
output: opened plugin=alsa name="My MPD Alsa Output" audio_format=44100:24:2
playlist: queue song 2:"Party Playlist/01 Umbrella [Feat. Jay-Z].mp3"
output: closed plugin=alsa name="My MPD Alsa Output"
^Clisten: listen_global_finish called
db_finish took 0.000000 seconds
And I hear the song play for less than a second before the audio_output driver is closed. There really aren't any error messages printed explaining why it's not working. I've also tried "oss", "esd" and "ao" for the audio_output type, and none of them work.

I'm looking for a program that will visualize anything that goes through my audio-output (in this case it's Spotify) and display it on the screen. Does this exist?

My audio setup is based on a single guitar amplifier, and from this I suffer from only being able to listen to one of the two stereo channels. Since I honestly don't care for stereo, I'd rather force Ubuntu to output all audio as mono instead of "upgrading" to a stereo compatible setup.Is there a way to do this?

I have this file:Code:vid-gd-19940626-peggy.rmI would like to extract the audio and copy to a file to burn on a CD.'pitivi' will load the file and show the audio timeline. But I can not find a save or copy button.'vlc' will play the file but I can not find how to seperate/save the audio.I found a 'ffmpeg' that is suppose to read whatever is being sent to your speakers.Code:ffmpeg -f oss -i /dev/dsp -f video4linux2 out.wavThis produce a file that 'mplayer', 'vlc', 'audacity' will load but it is empty of useful data. Black screen only.This is the second week I have worked on this. Either I'm googling for the wrong words or what I'm reading, I don't understand.

I am honestly uncertain if I ever had audio. I thought I did, but that may have been a different machine or a different install. I don't frequentl use anything that requires audio. Nothing is obviously muted, amixer has everthing turned up at least half way.

I want to make the audio available only on my headset and to turn the laptop speakers off. In windows, when i plug in the headphones, the speakers automatically turn off and audio is output only on the heads but that's not the case with slackware. I was looking in alsamixer and the audio and video configuration, but no success.

I'm running Ubuntu 10.04 in a Dell XPS M1330 laptop with Intel gma X3100 integrated graphics. I occasionally use it for watching movies in an LCD TV, however when I connect it I can get it to output video fine, but audio is a no go, when I select hdmi audio in the sound options I get no sound.
