[PATCH v3 6/6] ASoC: qdsp6: q6apm-dai: fix playback dsp pipeline underruns
From: srinivas . kandagatla
Date: Tue Mar 04 2025 - 05:59:38 EST
From: Srinivas Kandagatla <srinivas.kandagatla@xxxxxxxxxx>
QDSP has latency of 10 plus milli seconds, Which is difficult to acheive
with just 2 periods and fragment size starting at 128. Increase the number
of fragments to 8 so that it fulfils the dsp requirements
Without this patch, DSP playback pipeline seems to hit few underruns.
Fixes: 9b4fe0f1cd79 ("ASoC: qdsp6: audioreach: add q6apm-dai support")
