From ad88ea67b135f74a9f32dc5404a35c773b2a3925 Mon Sep 17 00:00:00 2001 From: Pavel Hofman Date: Tue, 16 Apr 2024 14:17:25 +0200 Subject: [PATCH] ALSA: pcm: add support for 705.6kHz and 768kHz sample rates Many modern codecs support 705.6kHz and 768kHz sample rates. Current HW params fail to set 705.6kHz and 768kHz sample rates as these are not in the known-rates list. Add these new rates to the known-rates list to allow them. Also add defines in pcm.h so that drivers can use it.
