[BUG] Playback speed is 2x too slow with SoundWire link based on audio cardinal clock #8251
Closed as not planned
Description
Describe the bug
When the SoundWire link clock is configured to 12.288 or 6.144 MHz (Audio Cardinal clock as source), the playback duration is 2x longer than normal
This does not happen with 12 or 6 MHz (Audio PLL as source) or with 9.6/4.8 MHz (Xtal as source).
To Reproduce
Steps to reproduce the behavior: (e.g. list commands or actions used to reproduce the bug)
Reproduction Rate
100%
Expected behavior
playback duration is correct
Impact
showstopper
Environment
This relies on a Linux kernel change thesofproject/linux#4605 and can be seen on both MTL and LNL RVPs with RT711 on link 0
