[BUG] DMIC capture fails to DSP out of memory with GCC build

[singalsu]

Describe the bug
Running DMIC capture with four channels fails in 2nd - 6th time with topology sof-hda-generic-4ch.tplg.

To Reproduce

#!/bin/bash

set -e

arecord -Dhw:0,6 -f S32_LE -c 4 -r 48000 -d 3 rec.wav
sleep 1
arecord -Dhw:0,6 -f S32_LE -c 4 -r 48000 -d 3 rec.wav
sleep 1
arecord -Dhw:0,6 -f S32_LE -c 4 -r 48000 -d 3 rec.wav
sleep 1
arecord -Dhw:0,6 -f S32_LE -c 4 -r 48000 -d 3 rec.wav
sleep 1
arecord -Dhw:0,6 -f S32_LE -c 4 -r 48000 -d 3 rec.wav
sleep 1
arecord -Dhw:0,6 -f S32_LE -c 4 -r 48000 -d 3 rec.wav

Reproduction Rate
Always in 2nd - 6th capture.

Expected behavior
Successful repeated captures.

Impact
Blocker for gcc builds.
