Subject: [alsa-devel] [RFC PATCH 2/3] ALSA:core: Add rate 24kHz
Date: Thu,  5 Sep 2019 07:33:00 +0200	[thread overview]
Message-ID: <20190905053302.9262-2-pawel.harlozinski@linux.intel.com> (raw)
In-Reply-To: <20190905053302.9262-1-pawel.harlozinski@linux.intel.com>

Adds SNDRV_PCM_RATE_24000 at the bottom to keep backward compability
with alsa library.
