File 0009-pcm-Add-snd_pcm_audio_tstamp_type_t-constants.patch of Package alsa
From ea02dbd20a535085638c63c6b8bec94e628486c4 Mon Sep 17 00:00:00 2001 From: David Henningsson <diwic@ubuntu.com> Date: Wed, 16 Dec 2020 19:55:22 +0100 Subject: [PATCH 09/33] pcm: Add snd_pcm_audio_tstamp_type_t constants These are mostly a copy-paste from the kernel headers. But since functions snd_pcm_audio_tstamp_config make use of these they should be added to the public API as well.
