removing COPYING.GPL from alsa-plugins?

6 Sep 2023


      Hi Alsa-devel,
While reviewing the license for alsa-plugins-1.2.7.1, I noticed that it has
both a COPYING and a COPYING.GPL file.  The only plugin that possibly has a
GPLv2 license is rate/rate_samplerate.c, which has this at the top of the
file:
* Rate converter plugin using libsamplerate
 *
 * Copyright (c) 2006 by Takashi Iwai tiwai@suse.de
 *
 * This plugin code is supposed to be used and distributed primarily
 * under GPL v2 or later, in order to follow the license of libsamplerate.
 * However, if you already own a commercial license to use libsamplerate
 * for dynamic linking, this plugin code can be used and distributed also
 * under LGPL v2.1 or later.
So it seems like rate_samplerate.c is licensed as GPLv2 in order to be
consistent with libsamplerate.  But in 2016, libsamplerate dropped its
commercial license requirement and was released with the 2-Clause BSD
license.   (See http://libsndfile.github.io/libsamplerate//license.html)
So I was wondering if the license for rate_samplerate.c can be updated to
remove the GPLv2, which means the COPYING.GPL file can also be removed from
the package?
Thank you!
Michael
