Subject: [PATCH] ASoC: rt5650: Eliminate the high frequency glitch
Date: Thu, 10 Jul 2025 19:34:02 +0800 [thread overview]
Message-ID: <20250710113402.23334-1-derek.fang@realtek.com> (raw)
From: Derek Fang <derek.fang@realtek.com>
The glitch was detected in the high frequency of the HP playback.
This patch adjusts the DAC dither setting to avoid this situation
for almost all cases.
