ASoC: SOF: ipc4/Intel: Fix delay reporting
Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>: The current version of delay reporting code can report incorrect values when paired with a firmware which enables this feature. Unfortunately there are several smaller issues that needed to be addressed to correct the behavior: Wrong information was used for the host side of counter For MTL/LNL used incorrect (in a sense that it was verified only on MTL) link side counter function. The link side counter needs compensation logic if pause/resume is used. The offset values were not refreshed from firmware. Finally, not strictly connected, but the ALSA buffer size needs to be constrained to avoid constant xrun from media players (like mpv) The series applies cleanly for 6.9 and 6.8.y stable, but older stable would need manual backport, but it is questionable if it is needed as MTL/LNL is missing features.
