[PATCH v3 4/6] ASoC: qdsp6: q6apm-dai: set correct period and buffer alignment.

From: srinivas . kandagatla
Date: Tue Mar 04 2025 - 05:59:23 EST


From: Srinivas Kandagatla <srinivas.kandagatla@xxxxxxxxxx>

DSP expects the buffers to be aligned to 64 bytes. Having a 32 byte
alignment can result in fast playback or capture in some configurations.

Fixes: 9b4fe0f1cd79 ("ASoC: qdsp6: audioreach: add q6apm-dai support")
