Subject: [PATCH v1 2/2] ASoC: qcom: q6dsp-lpass-ports: Add support for 32-bit PCM format
Date: Tue, 18 Nov 2025 15:32:03 +0530 [thread overview]
Message-ID: <20251118100203.2751955-3-ravi.hothi@oss.qualcomm.com> (raw)
In-Reply-To: <20251118100203.2751955-1-ravi.hothi@oss.qualcomm.com>
From: Ravi Hothi <ravi.hothi@oss.qualcomm.com>
Introduce support for 32-bit PCM format (SNDRV_PCM_FMTBIT_S32_LE) in
addition to existing 16-bit and 24-bit formats. This allows handling
high-resolution audio streams and improves audio quality for supported
hardware.
