From 71d218eae4b4d93ada34ff74906f71ad359c84bc Mon Sep 17 00:00:00 2001 From: wm4 Date: Sat, 28 Mar 2020 20:51:43 +0100 Subject: ao_sndio: remove this audio output It was always marked as "experimental", and had inherent problems that were never fixed. It was disabled by default, and I don't think anyone is using it. --- audio/out/ao.c | 4 - audio/out/ao_sndio.c | 319 --------------------------------------------------- 2 files changed, 323 deletions(-) delete mode 100644 audio/out/ao_sndio.c (limited to 'audio') diff --git a/audio/out/ao.c b/audio/out/ao.c index 42e2cf63d5..a414b1b6b9 100644 --- a/audio/out/ao.c +++ b/audio/out/ao.c @@ -41,7 +41,6 @@ extern const struct ao_driver audio_out_audiounit; extern const struct ao_driver audio_out_coreaudio; extern const struct ao_driver audio_out_coreaudio_exclusive; extern const struct ao_driver audio_out_rsound; -extern const struct ao_driver audio_out_sndio; extern const struct ao_driver audio_out_pulse; extern const struct ao_driver audio_out_jack; extern const struct ao_driver audio_out_openal; @@ -88,9 +87,6 @@ static const struct ao_driver * const audio_out_drivers[] = { #endif #if HAVE_SDL2_AUDIO &audio_out_sdl, -#endif -#if HAVE_SNDIO - &audio_out_sndio, #endif &audio_out_null, #if HAVE_COREAUDIO diff --git a/audio/out/ao_sndio.c b/audio/out/ao_sndio.c deleted file mode 100644 index e5938b7d26..0000000000 --- a/audio/out/ao_sndio.c +++ /dev/null @@ -1,319 +0,0 @@ -/* - * Copyright (c) 2008 Alexandre Ratchov - * Copyright (c) 2013 Christian Neukirchen - * - * Permission to use, copy, modify, and distribute this software for any - * purpose with or without fee is hereby granted, provided that the above - * copyright notice and this permission notice appear in all copies. - * - * THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES - * WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF - * MERCHANTABILITY AND FITNESS.
