 Posted: Thu Feb 04, 2010 8:08 pm Post subject: No sound in some apps |
 |
|
I recently installed Gentoo and everything has worked great except for sound. I have sound in Songbird but no other applications. Also, when I go to System > Preferences > Sound in Gnome, a window comes up that says 'Waiting for sound system to respond" and it doesn't go away until I cancel it.
I tried following the instructions at http://en.gentoo-wiki.com/wiki/PulseAudiobut I'm missing /etc/init.d/pulseaudio. I did notice that if I reemerge pulseaudio I get sound back in other apps, but as soon as I run Songbird it stops working again.
I've tried emerge --newuse world but that didn't fix anything. I'm not sure what else to do! Any help would be appreciated. |

Major part of that wiki page is too outdated to bother with following it.
If you're running Gnome session manager, you most probably don't need that scrict
-pulseaudio should run for your user. |

|
|
Thanks for the reply! I finally managed to get pulseaudio working by commenting out load-module module-console-kit in /etc/pulse/default.pa. Now everything works how I want except for audio in Flash 10. It doesn't show up in the PulseAudio Volume control at all.
For example, if I'm listening to a song in VLC, while using Firefox and decide to watch a Flash video, I have to close Firefox and VLC and then reopen Firefox or I won't get sound in Flash videos. If I try to restart the music before closing Firefox, the song will load but play without sound. As soon as I close Firefox, the music starts playing.
Edit: Just noticed this error in syslog but not sure what it means:
| Code: | | pulseaudio[3791]: alsa-sink.c: Error opening PCM device front:0: Device or resource busy |

Try this one:
www-plugins/libflashsupport
It's description says: Adds pulseaudio/esd/oss audio output and HTTPS/RTMPS support to Adobe Flash 9
These kind of dependency's made me wonder whether it's worth installing and using pulseaudio  |

| Unfortunately, installing libflashsupport didn't help. These dependencies are definitely making using pulseaudio a pain, but so far it's working with everything else. Flash/Firefox seems to be the only issue, but according to some research I've done, Flash 10 is supposed to work with pulseaudio out of the box. I'm not particularly attached to Pulseaudio if you know of a good alternative. I don't need any fancy effects; I just want to be able to hear sound in different programs without having to close one to hear the other. |

Auch... (it was worth a try though :p )
http://macromedia.mplug.org/:
8. Remove libflashsupport as it is no longer needed for anything with Flash 10, and it might even be the cause of crashes.
Yes, you were right about the out of the box support:
http://en.gentoo-wiki.com/wiki/PulseAudio#Flash_support:
Flash Player 10: Flash 10 should work well with PulseAudio out-of-the-box, if the alsa device named "default" is configured to use the pulse plugin, as instructed in the ALSA section above on this page.
Is your device correctly configured? |

No luck so far, but I'm still working on it. I tried using that Pulseaudio wiki that the page recommends for Alsa but I can't find the file that it mentions because it's not in those locations on my computer. Here are the instructions that it gives:
| Quote: | To activate the driver edit /etc/asound.conf or ~/.asoundrc and add:
pcm.pulse {
type pulse
}
ctl.pulse {
type pulse
}
|
Any idea where that file might be? I have Alsa installed and all of the plugins that it says are needed. Using locate doesn't find either file either, but that hasn't been super reliable in the past either... |

If it helps, here's my /etc/pulse/default.pa. I noticed a section that mentions alsa, but I don't want to mess with it since I'm not completely sure what it does.

| Yay! I managed to solve it! All I had to do was create the alsasound.conf file and add the text that the tutorial said to add. Not sure why I waited so long before just trying that, but better late than never, right? Thanks for the help! |

Um, where would you create alsasound.conf, and the text from which tutorial?
Have similar sound issues but on KDE4.
thanks, Ian

Ian,
The instructions I found are here:
http://www.pulseaudio.org/wiki/PerfectSetup#ALSAApplications
It worked for a few days but then went back to how it was, so I'm not sure if it was just coincidence or if I just messed it up by doing something else. I've since had to reinstall Gentoo for other reasons and this time I decided to try it without PA or the pulseaudio USE tag. Everything is working perfectly now. Let me know if that works out for you though! |

I don't have pulseaudio installed, nor a pulseaudio use flag.
Everything was working perfectly until I upgraded from KDE 3.10 to the 4 series (stable releases).
Other people have the same problem and since you are on gnome maybe we've been looking in the wrong place for the problem.
thanks, Ian

crazymonito ... why not just use plain old alsa and no sound system. If you don't need "fancy effects" just plain old also works for me for everything from music (exaile), movies (mplayer), firefox (flash, last.fm, etc...), and whatever else .. all at the same time if you like too

bobspencer123 That's what I ended up doing and it's working exactly how I want! I was originally trying to get PA installed because I was under the impression that it was required to have sound work in different programs at the same time. Living up to my n00b status! 
ian Installing without PA fixed the issue for me but since you're having the same issue on KDE, do you think it might be something that PA pulled in when I installed it? It could be something that we both have. I'm not sure what else PA pulls in though, and I'm not at home to check. |

What codecs have you installed in your PC?
Have you tried real player or VLC?
Did you install the codecs before you have installed the audio drivers?
Check these and get back here |

If you can advise an easy way to check which codecs I'd be happy to oblige 
Here's the (hopefully) relevant flags from make.conf
| Code: |
USE="aac alsa ffmpeg flac gstreamer mmx mp3 mpeg mplayer nsplugin ogg quicktime raw timidity v4l v4l2 vcd vorbis win32codecs wmf xine"
|
However when K3B starts up it bitches about missing mp3 decoding stuff (which it never did in KDE 3.10). Have been unable to resolve this as well.
As explained in other threads, it is difficult to have sound from more than one application.
If I start up Kmail, no other sounds work. If I shut down Kmail, then kill any hanging threads (kio_pop3), then start up Amarok or VLC or ffplay or YouTube in Firefox, then I will have sound. If Kmail was running, there will be no sound in those apps.
If Amarok is playing and I view a video on YouTube, there will be no sound from the video.
This stuff all worked fine in KDE 3.
thanks, Ian
