    Question What do you feel about PulseAudio?

    Well, I have been playing around PulseAudio to see how it works. I realized its impossible to play 2 audio streams at the same point. Under System>Prefs>Sound I selected ALSA for all the devices and I managed to play 2 audio streams.

    Then I browsed through PulseAudio website for a guide and I came across a Perfect Setup guide. The guide mentioned to install all the GUIs required to configure PulseAudio. I installed them and checked all the options, there was a lot of stuff and I didn't want to mess my system up further.

    After all this, I am wondering why the devs have included PulseAudio in a LTS release. Is there any advantage PulseAudio can give that ALSA cannot. On 7.10, ALSA didn't give any problems, so why is PulseAudio installed by default.

    it has lots of cool low level stuff

    the comparison is like xine and gstreamer, xine was initially better supported but gstreamer is fundamentally better

    pulseaudio should support it, i suggest you submit a bug report

    run the command pavucotrol to see one of the cool things based on it

    Re: What do you feel about PulseAudio?

    I am having some sound issues with Hardy, and I assume this is to do with this new PulseAudio. I'm unable to play different audio streams at once, for example if I'm playing a YouTube video I don't hear any sounds from any other apps. After the videos have finished and I close YouTube, sound still doesn't work until I reboot. Really annoying, have you reverted to ALSA somehow? I have never had these problems in any previous releases.

    Edit: Submitted this post and I was looking at other posts in silence and suddenly my computer went "BAABUMTSCHCHHTSCHHBUMMBAAMMTSCCHH" (a mix of a constant beep and the Ubuntu login sound if you couldn't tell!) and almost killed me it scared me so much! Got to get this little problem sorted!

    you need to type these line into terminal (one by one) to fix flash
    Code:
    wget http://pulseaudio.vdbonline.net/flashplugin-nonfree-pulse_0.1~000.tar.gz
    tar xvfz flashplugin-nonfree-pulse_0.1~000.tar.gz
    cd flashplugin-nonfree-pulse-0.1~000
    sudo apt-get install libpulse-dev
    make
    sudo make install

    Under System>Prefs>Sound I have chosen ALSA instead of the default "Autodetect" to play all the sound events. With this I can play multiple streams

    Thanks for that it worked great! This version of the Flash plugin should really be offered for download by Firefox and/or be in the repositories since it is needed for it to work properly.

    I haven't had any problems with it so I don't mind it, but I was curious as to what it's purpose is as well.

    Re: What do you feel about PulseAudio?

    You can play multiple streams I had that problem with Alsa but pulse audio fixed that..

    There are many other benefits to pulse audio since you can "merge" sound cards to act as one so you can be hooked up to a headphone jack and everyone else can listen through a speaker set so you can preview songs or other audio files. It is really great for Digital Dj's.
