Switching to use pipeline parameters to get NHLT blob breaks audio on HP Chromebook 13 G1 (at least with MrChromeBox firmware).
Fix this by retrying to get NHLT blob with PCM parameters (which is the old behavior) if pipeline parameters fail.

Hello,
Could you share the NHLT file from your platform plus the format used by the cras/userspace tool? Did you try playing over simple aplay tool instead?
I tried 48000Hz 2ch 32bit with speaker-test.
Attached is /sys/firmware/acpi/tables/NHLT.

Drop the "old behavior" - most of the readers are not aware of what that actually means.
