    Any help ?

    [my config: Acer Aspire 9920G Laptop 4GB RAM - 20in. screen laptop with 1 subwoofer, 5 HP, Intel audio integrated with Dolby Digital - Ubuntu 8.10 Fresh install]
    PLEASE - IF SOMEONE KNOWS:
    Is there any way to tune the ~/.asoundrc file to get the sound amplified while getting it equalized ?

    So is their incompatability issues with this flash upgrade or what? i am still having probels since upgrading FLASH-PLUGIN INSTALLER and apparently others are too

    edit: I do notice that in pulse audio volume manager, the flash volume display goes in an out quickly. It displays it for like a millisecond and disappears over and over

    Fixed it. I had to manually DL the tar.gz from the adobe site and then drag to libflashplayer.so file into my /home/NAME/.mozilla/plugins directory.

    I tried to follow your instructions but it seems that I still can't get sound to work. I'm using Intrepid Ibex AMD64

    Re: HOWTO: PulseAudio Fixes & System-Wide Equalizer Support

    On my system (Intrepid Ibex, clean install), Pulseaudio works for a while--Usually a day or so. It eventually dies. Killing and restarting it restarts sound, but I have to restart Firefox to get Flash to work again.

    Upgrading from Hardy to Intrepid had similar issues, but quicker.

    Original install of Hardy had no sound problems at all.

    What should I be looking at next time it dies on me?

    I updated my Ubuntu 8.04 to 8.10 today and restored my backup
    i had a few videos in 3gp and they were playing but without any sound..
    the mp3 files were playing with sound
    then went to youtube and tried to play a video.. but no sound
    Same was the case with Bluetooth stack of my laptop
    was seriously considering to go back to Ubuntu 8.04 and then came across your article
    Works wonderfully now... thanks man..
    highly recommended

    I am running Ubuntu Hardy Heron on a Lenovo Thinkpad T61 laptop. I followed the above directions but I cannot start pulseaudio without serious looking errors. This is my output, first short then long:

    Just carefully followed the steps on my Acer Hardy Heron. Whoa!! GREAT!
    The equalizer stuff is really nice!

    Re: HOWTO: PulseAudio Fixes & System-Wide Equalizer Support

    For the record, I think Pulseaudio is a great enhancement to Linux audio. Now, I recently installed Hardy Heron, and had to struggle a while to get it output sound through my chipset's (HDA Intel) S/PDIF, but eventually found it out by following this quide, and reading from some other thread, that you have to manually add the device to /etc/pulse/default.pa:
    Code:
    # intel hda digital audio
    load-module module-alsa-sink device=hw:1,1
    As you can see, I have two sound cards, so chipset lists as second card, and digital is the second channel. So device is hw:1,1.

    Now the last problem I have, is that VMware sound stutters quite a bit. I managed to put virtual machines' sound through Pulseaudio OSS wrapper by following this guide: http://communities.vmware.com/thread/163605. At the end of the guide he suggests trying out different values for default fragments. However, dispite of trying different combinations, I've not had much success with the problem. So I'm asking, has anyone figured out appropriate values with hardware similar to mine?

    Btw, I don't think, that adjusting these values is something, that end user should have to do. Are problems with VMware already fixed in recent PA releases?

    Re: HOWTO: PulseAudio Fixes & System-Wide Equalizer Support

    Hi all,

    i am experiencing the well known Firefox bug, it's closing randomly when playing flash websites...

    - Firefox is running on a VMware Virtual Machine with Ubuntu 8.04 LTS
    - I tryed to follow this guide here (topic start) but since i have no soundcard in my virtual machine implemented, i can not open the audio control etc. i can not add a soundcard to my VM because i am using VMware ESXi. This means i have no chance to complete the mentioned guide.
    - I did a upgrade to 8.10, but i am experiencing the same Firefox problem

    Please, what can i do in order to have a stabil Firefox that can play FLASH?

    Which Ubuntu Version has NOT this bug that have cost me some much stress so far?

    thx a lot in advance
