I'm working on docs for ossaudiodev, and I thought I'd ask here before bugging the OSS people: does anyone know which operating systems use OSS (Open Sound System) as the standard audio interface? I know Linux up to 2.4 does, as do some (all?) versions of FreeBSD. Do any of the other BSD flavours (OpenBSD, NetBSD, ...) use OSS out-of-the-box? (If you have access to a FooBSD box, take a look for /usr/include/*/soundcard.h -- if it looks like this: """ #ifndef SOUNDCARD_H #define SOUNDCARD_H /* * Copyright by Hannu Savolainen 1993-1997 [...] """ then it's OSS.) Anyone know precisely which 2.5.x version of Linux dropped OSS in favour of ALSA? Please reply directly to me -- my python-dev subscription is temporarily disabled because I went on holiday a week ago, and still haven't caught up with my other email backlog... Thanks -- Greg -- Greg Ward <gward@python.net> http://www.gerg.ca/ I just read that 50% of the population has below median IQ!

I'd say 'recent'. I don't recall when it was added, definately a while back, but the oldest machine I have (FreeBSD 4.2) has OSS/Free. From googling I get the impression that it's been there since 3.x, so 'recently' definately holds. Likewise, googling shows OpenBSD also uses OSS/Free -- the commercial OSS installation manual tells you to remove references to OSS/Free from the kernel :) And there's a boatload of supported platforms in the commercial OSS of course, see www.opensound.com. But I don't suggest we try and plug OSS :)

OSS wasn't dropped (not yet anyway), ALSA was added. Also, ALSA has an OSS emulation mode, so I think it's safe to say you need to 'have OSS or ALSA with OSS API emulation' enabled. -- Thomas Wouters <thomas@xs4all.net> Hi!
