Please explain the problem.
In Qualcomm audioreach setup, if platform dai not specified in DT, then cpu dai using as platform and initialize as static dai-link and created pcm device and link-dynamic == false by default.
In existing setup if dynamic==false, it's skipping trigger snd-ops and the codec is always on mute state.

I dont think any of the Qualcomm upstream platforms use this flag.
Yes, we are using dynamic flag and it's set to true in Qualcomm platforms.
Please check: https://git.kernel.org/pub/scm/linux/kernel/git/broonie/ sound.git/tree/sound/soc/qcom/qdsp6/topology.c#n1093
only on `snd_soc_dai_mute_is_ctrled_at_trigger()`. This patch ensures that mute and unmute is applied explicitly for non-dynamic links.
How is this resolving the issue, mute on these codecs happens at trigger level instead of prepare.
yes agree, but if link->dynamic==false the trigger ops not getting called, which leading to codec always on mute state.
This is because you are using something very different solution to what ASoC kernel provides.
I dont think this is a problem with as long as you use kernel ABI..
This patch looks totally a hack from something that does not belong to kernel, so is NAK from my side on this.
