    Re: No sound in Maverick after installing Flash player

    I, too, have this problem, and after much mucking about, I've discovered that it *is* Flash that's causing the problem. I just don't know how to fix it.

    Yesterday (in Karmic) I updated Flash in order to watch videos on Hulu. I lost my sound. I decided it was a good time to upgrade to Lucid, so I did so. Still no sound (and Songbird died).

    Nothing is muted in Alsamixer.

    I could go into System Settings and play test sounds on the analog outputs (I have no digital sound devices), but YouTube wouldn't play sounds.

    Reboot, and sound comes back for a while. I watched a couple vids in MPlayer, and the sound worked fine. Went to sleep, got up... no sound again--the very last thing I was doing last night was watching a video (MPlayer), sound just stopped on it's own.

    Today... I muck about with settings some more, try to test sound, and get it to come back in the System Settings test mode. Play a video in MPlayer; it has sound. Try to play Songbird; no sound. Try a video again; it has sound. Try YouTube; no sound. Go back to the same MPlayer video (20 seconds later)... And the sound is dead. Wait a couple minutes (to write this far), test in System Settings and I have sound. Test the MPlayer, I have sound. Play Songbird; no sound. Try the MPlayer again, no sound.

    And... to wrap it up, I just tried to test in System Settings, and I get "device does not work" on both of the analog options.

    This is *very* frustrating.

    I've dug through the forums here and done my best with websearches. This is the only place I've seen this listed. Any help or pointers would be greatly appreciated.

    Try resetting your pulse config.
    Using a Terminal="Applications->Accessories->Terminal"
    Code:
    rm -r ~/.pulse ~/.asound* ~/.pulse-cookie 
    sudo rm /etc/asound.conf
    Logout/in.

    No joy? Run theses commands and post the terminal output:
    Code:
    sudo alsa force-reload
    pkill pulseaudio; sleep 2; pulseaudio -vv

    I have i.386 computer and Ubuntu 10.10
    after upgrading I lost the sound
    The following information works for me:

    Just a hint to spare the time of the next who may experience this: when using a SDL 1.2.14 built from sources (with options --enable-video-directfb=no --disable-rpath --prefix=XXX -exec-prefix=YYY), at least on Ubuntu Maverick, with the resulting library no sound was available ("No available audio device").

    I could check that PulseAudio was activated and running (/usr/bin/pulseaudio --start --log-target=syslog), but at SDL configuration-time the PulseAudio support got nevertheless deactivated:

    """
    checking for ALSA CFLAGS...
    checking for ALSA LDFLAGS... -lasound -lm -ldl -lpthread
    checking for libasound headers version >= 0.9.0... not present.
    checking for snd_ctl_open in -lasound... no
    checking for artsc-config... no
    checking for esd-config... no
    checking for ESD - version >= 0.2.8... no
    *** The esd-config script installed by ESD could not be found
    *** If ESD was installed in PREFIX, make sure PREFIX/bin is in
    *** your path, or set the ESD_CONFIG environment variable to the
    *** full path to esd-config.
    checking for pkg-config... /usr/bin/pkg-config
    checking for PulseAudio 0.9 support... no
    checking audio/audiolib.h usability... no
    checking audio/audiolib.h presence... no
    checking for audio/audiolib.h... no
    checking for AuOpenServer in -laudio... no
    """

    After some investigation, to enable PulseAudio support in the resulting library, you must have libpulse-simple.* files, which are provided by the libpulse-dev package.

    Then build and execution works as expected (with proper sound).

    Best regards,

    Olivier Boudeville.

    Bump... I'm having this issue too. Sound is working at boot but after watching less than 5 minutes of Flash video online, it stops.

    Is there any new information on this? Did the OP ever resolve this?

    Thanks

    Following up, lidex's first code snippet did the trick. I don't have asound installed but clearing the pulseaudio and cache folders got everything working again.
