Hm, so actual problems were confirmed fixed with this? That seems rather strange, since that would mean the hardware counted the clock cycles wrong for the CTS value... Maybe the HW doesn't do it per-spec, instead calculating CTS in some other way?
Yes. Using the sw cts/n values resulted in better results across asics compared to the alternative fix (using the actual pll clock for the dto calculation). Using the hw cts/n values lead to playback speed issues on some asics.
