    Re: pulseaudio equalizer

    Hi again,

    I updated the file - could you test again? It should print alot of debugging output if you do -d on it this time if you still have problems. I believe I found the cause or at least a related bug. Same link (here)

    Re: pulseaudio equalizer

    OK thanks, this seem to work now. I can only get 33 sliders though. Here is the debug output after starting and resizing to the max width of my screen's roslution (1280), it's kinda long but I included everything.

    Code:

    Re: pulseaudio equalizer

    This sounds like great work.

    For me,at the moment I will stay using 'psyke83' package as it is easy to install. (http://ubuntuforums.org/showthread.php?t=1308838)

    As a tip could I recommend that we bear in mind desktop space for us netbook users (mostly running at 1024 x 600).
    I don't fancy having 100 od bands for adjustment when my desktop would not show all of them but then only 7 bands would be poor (if you understand what I mean).

    Still great work.

    Any news on installable deb files ?

    Re: pulseaudio equalizer

    I just wanted to say thank you for your work involved with this. The PPA made things quite simple, though it took me a lil while to figure out how to compile/install the qpaeq (sorry I'm still a noob when it comes to compiling); Once I added the eq sink to my default.pa the program loaded fine and I could stretch the eq across my screen (1680*1050) netting me 44 eq channels I can now actually hear sounds in the low range when I listen to music! I did notice some scratching/overdriving on certain programs like Mumble, I got around this by setting my main sink as my sound card w/o the EQ on it, then using the pulseaudio volume control to manually choose the eq sink for Rhythmbox. I don't know why Rythmbox can handle the eq sink and mumble can't, but I'm not complaining. I suppose I should start a separate thread on the matter. Either way, thanks again for this!

    Re: pulseaudio equalizer

    I'll ask again why it is more important that Karmic gets an equalizer PPA while Lucid gets no PPA and an unreasonable "no" from ubuntu audio dev to even the idea of including it in Lucid when currently released versions already support it.

    Starks,

    sorry for the late reply, I'll get around to the lucid ppa soon I hope. The audio dev members mentioned to me they'd provide it in their ppa or a sister ppa some months ago, but that hasn't happened.

    As for the next release not having it by default... while I sympathize with it being an LTS release and needing to be as stable as can be... it's just a runtime optional module... this is the kind of logic that chases me away from a distro .

    Re: pulseaudio equalizer

    Any chance you've had time to get around to a Lucid PPA for this, phish3?

    Re: pulseaudio equalizer

    Hi

    I tried to compile the equalizer in fedora12 following your instructions on the pulseaudio wiki.
    The makefile finished succesfully.
    But I then tried a fake install and saw it wanted to install these files:
    libpulsecommon-0.9.19.la libpulse.la libpulse-simple.la libpulse-browse.la libpulse-mainloop-glib.la libpulsedsp.la libpulsecore-0.9.19

    In fedora12, pulseaudio is 0.9.21
    How can I fix this?
    Is it in the configure? or the version is hardcoded?

    Thanks
