LPC: Linux audio: it's a mess
Posted Sep 19, 2008 14:12 UTC (Fri) by drag (subscriber, #31333)
The PA in Hardy was, as far as I can tell, a victim of bad QA.
And Adobe Flash does crash out my browser quite often. Most of the time when I close out a window which I just watched a video, which follows that race condition described in the above article. This hasn't anything to do with PA, since you know, I am not actually running it.
I am sure you have other good reasons, but switching to Windows to fix Youtube is a bit drastic when it could of been solved by turning off PA or/and installing some other flash player. :)

Actually the browser window problem didn't affect me, because I use tabbed browsing, just one window which I don't close.

The Linux desktop experience is much more buggy and crash happy then Windows nowadays. People need to learn that having the source code is not a acceptable substitution for binary compatibility and good quality control mechanisms. It hurts open source software just as much as closed source stuff.

LOL, I don't think so - although, who knows - I haven't run windows for some time, does it not crash anymore? Wow, that would be one for the books.
The linux desktop with pulseaudio has been working well for me (suse 11.0 at home, ubuntu hardy heron at work) but then again, perhaps my sound hardware is blase? (intel built-in) I do the usual, some web browsing, some gaming, some movies, some music. Other than a wrapper script that I needed for my 9 year old copy of quake 3 arena, everything just seems to work, out of the box.
Alternative for Adobe Flash users

So I had to remove Gnash and replace it with the original Adobe Flash plugin.
(Unfortunately although there's a straightforward UI from Firefox asking which Flash plugin you'd like to install (I'd picked Gnash), there seemed to be no UI for removing or changing it.)
Disable Flash in the Browser

e.g. the backup domain controller went down at work today (our desktops
are Windows XP *sigh*). Within seconds *everything* on *everyone's*
desktop had frozen. Even my VNC and X sessions were stalled. Most of the
mouse pointers had frozen (but not all), and ctrl-alt-del did nothing.
Even the primary domain controller froze. It all stayed stalled until both
the primary and backup domain controllers were simultaneously rebooted.
That's robustness for you. (If everything's frozen solid, it can't crash.)
The time was when heavily-interlinked NFS systems could do that in the
Unix world, but I haven't seen anything like it for many years, and even
at its worst Unix gave you more tools to diagnose it than roomfuls of
simultaneously-frozen boxes. In some ways Windows is going *backwards*,
even before you look at the Vista trainwreck.
It's not the only mess

Maybe I'm biased because I use only debian testing, and maybe Mandriva or Suse are better. And of course there are areas where it excels (such as performance and support for older hardware). But I'm not sure there aren't at least some engineering reasons for the lack of quality. Windows or Mac OS X have one wireless API well thought from the beginning, and most gadgets work fine with it (while Linux still struggles with common wireless chips). More to the point, they have not had two major rewrites of their sound systems in a few years (ALSA and PulseAudio).
Things should just work, and once they are working they should just keep working, without excuses.

This is very much present tense at my workplace...

As well as having a working libflashsupport Fedora also runs plugins
inside nspluginwrapper, even on 32 bit installs. That means that flash
runs isolated in its own process and doesn't take out your browser when

Also the problem crops up in other applications that can support Mozilla plugins, like Liferea.
I will take a look at nspluginwrapper, though.

I installed and got PulseAudio working in Debian. And everybody above was right.. flash 9 doesn't work for shit. If I do the "export FLASH_FORCE_PULSEAUDIO=1" I can get it to sort of work for firefox, but not for anything else.
So I installed the Flash 10 beta and it seems to be much much better. Works happily with pulseaudio, but I had to disable framebuffer compression with the Intel driver stuff to get it to work without video corruption (of the flash video, not the display). This was in Debian Sid.
