Description Konstantin Svist 2010-02-03 08:28:42 UTC

Description of problem:
Some old code uses /dev/audio instead of /dev/dsp -- for instance, http://sourceforge.net/projects/max-gpl/

The program kept complaining about missing /dev/audio. After looking at the source (good thing it had one available!) and some googling (would be nice if pulseaudio had better documentation), I found that it works with OSS only and the way to make OSS-only apps work with pulseaudio is to run them through padsp.
When I tried that, it still failed because apparently padsp creates /dev/dsp but doesn't create /dev/audio
I was able to recompile the code with /dev/dsp instead of /dev/audio, but I don't think I should have to. Or rather, if someone has an old OSS-only application without sources and it uses /dev/audio, they should be able to run it with padsp

Comment 1 Lennart Poettering 2010-02-04 23:03:52 UTC

We no longer support the OSS API in Fedora. For a while we will carry a compat kludge which is padsp which supports correctly written OSS devices.

Instead of extending this kludge to /dev/audio I'd much rather see the apps in question being ported to ALSA or suchlike.

Comment 2 Konstantin Svist 2010-02-04 23:10:49 UTC

In this case it can be done because the app is open source, but I'm sure there are some proprietary apps that can't be so easily fixed

Comment 3 Lennart Poettering 2010-02-16 01:05:15 UTC

Fixed upstream, will upload to F12 eventually.
