Comment (by dan at coruskate.net):

 FYI, I built Mixxx 1.5.something from source.  1.5.what I'm not too sure -

 -rw-rw-r--  1 dan staff  4034791 2007-03-04 10:35
 mixxx-1.5.0.1-src.tar.bz2
 ... unpacks into a directory mixxx-1.5.0, opens a window titled Mixx
 1.5.0-beta2

 It mostly works (and it's great fun :-) but for two things:
 (1) on my ATI Radeon, it segfaults on startup in src/visual/material.cpp,
 somewhere inside glIsEnabled.  Commenting out the GL calls in
 Material::Material seems to fix this and have no other ill effect.  This
 has been informally reported to a developer on irc.freenode.net #mixxx

 (2) when linked against the version of portaudio in 64studio
 ii  portaudio19-dev          19+svn20060825-1         Portable audio I/O -
 development files

 it will rewrite its config ~/.mixxx.cfg file into uselessness (replacing a
 Jack config with an OSS one) when it exits if jackd is not running at
 startup.  Restarting it after that will cause it to send a SIGKILL to
 itself.   On the advice of IRC I upgraded my portaudio to the current SVN
 snapshot and this has apparently fixed the problem

 01:11 < asantoni> ok, I've heard of lots of strange JACK problems
 01:11 < asantoni> it might be the old audio code not playing nicely
 01:11 < asantoni> or it might be your PortAudio-v19 version
 01:12 < asantoni> possibly a combination of both
 01:12 < asantoni> I'd be interested to see if updating your 1) PortAudio
                   version and 2) Mixxx to SVN helps
 01:12 < dan_b> my PortAudio version is whatever came with 64studio
 01:15 < dan_b> ok, changed it back to jack in the Prefs dialog and it
 works
                again for the moment
 01:16 < dan_b> having it clobber the file like that's probably not good
 though
 01:16 < dan_b> ii  portaudio19-dev          19+svn20060825-1
 Portable
                audio I/O - development files
 01:17 < asantoni> yeah, that's fairly old
 01:18 < asantoni> dan_b: if you're feeling lucky, try PortAudio from SVN:
                   http://www.portaudio.com/archives/pa_snapshot_v19.tar.gz
                   (daily snapshot)
 01:39 < dan_b> hmm, that's a definite improvement
 01:40 < dan_b> if jackd is not running it now silently chooses alsa
 instead
                (which is still not in accordance witht he principle of
 least
                surprise, really) but at least it doesn't trash the config
 file
                for the next run

 01:33 < asantoni> dan_b: I'm probably going to commit your Material fix
 01:33 < asantoni> doesn't look like it does any harm
 01:33 < asantoni> but those are famous last words :)

 I don't know about the libmad issue, as this box was upgraded by apt-get
 from etch and so probably still has the debian libmad installed anyway.
