    PulseAudio version problems

    Hi,

    In solving a problem opening a .mov file I found this popup:

    Potential PulseAudio version problem:
    PulseAudio is streaming with an excessive latency. Sound may be lost or quality degraded.
    To address that issue, upgrade the PulseAudio daemon to version 3.0, or disable the alternate sampling rate in its configuration.
    The video/sound continues and closing the popup is the kludge solution.

    Having no idea of how to access the configuration, I then coded: # yum upgrade pulseaudio rpm.

    Looking at the result I find I went from v 2.1.4 to v 2.1.6.

    A search for PulseAudio v3 home led me here http://mpd.wikia.com/wiki/PulseAudio. From this, it seems PA is used for editing and other manipulations. Since all I want is to play back videos and the occasional mp3, this is not needed.

    It seems most video apps have their own audio so
    #
    Code:
    yum erase pulseaudio
    should eliminate the popup and let those work without(I hope) further complications.

    Any comments or suggestions?

    Re: PulseAudio version problems

    PulseAudio is an audio daemon. When programs want to output sound, they do so through PulseAudio, which mixes sound so that multiple applications can output at the same time etc. There are other things it does too.

    Most (older) programs can output directly to the sound driver (ALSA), by-passing Pulse, but it’s not a recommended or supported option. Expect complications.

    What program are you using to play the MOV?

    Re: PulseAudio version problems

    Hi Gareth,

    Thanks for your response; I'm learning more and more about pulseaudio. It seems to be more than I need, which is playback of videos and .mp3.

    When I click on the .mov file VLC opens it with audio.

    This leads to my next question. At an earlier point in this part of my learning curve I installed mplayer using Mauriat Miranda's code:
    # yum install mplayer mplayer-gui gecko-mediaplayer mencoder

    Since VLC does what I want I'd prefer to delete mplayer but I don't know if gui gecko or mencoder in the install code require inclusion in the erase code. I don't want to leave odd bits and pieces; what code would I need to clear it all out?

    Since I already have pulseaudio and don't need it I assume
    # yum erase pulseaudio
    will take it out.

    Thanks again for your info,
    jeb

    Re: PulseAudio version problems

    You will probably lose all of your audio if you erase pulseaudio

    The video/audio applications pass their audio output to pulseaudio, so you pretty much need the audio daemon to be installed. There are ways to remove pulseaudio and pass the audio directly to alsa, or use jack audio, but it's easier to use pulseaudio.

    It is quite a bit more complicated to remove pulseaudio than just a yum erase pulseaudio You do that, and you will probably remove most of your system with it.

    You can update to the newer version (3.0) of pulseaudio in Fedora 18 if you wish to. There is a repo available that has the 3.0 backport to f18 in it.

    http://repos.fedorapeople.org/repos/...audio-backport

    Here is the repo file to use for yum:

    Thanks for your quick response DB, among other things it reinforces waiting for a response.

    My impression of v 3 from the search is that it's pointed towards the handheld items flooding the market. Not an area of my interest, so 2.1.6 should suffice.

    Thanks again,
    jeb
