the changes look ok
But I still have the same problem: Audio plays slowly.
It seems the DSP is clocked at 19.2, but the system is still clocked for 25, and these changes doesn't seem to have effects...
no, CHT doesn't have a 25 MHz clock at all so that's just not physically possible.
Can you try: - tracing to make sure you are actually on a CHT device - pastebin dmesg somewhere - sudo cat /sys/bus/acpi/devices/10EC5651:01/status - enabling DSP loopbacks to see if the DSP consumes data at the right rate. look at the UCM file and change cset "name='pcm1_out mix 0 pcm0_in Switch' off" to on if you record and loopback on USB output this should play at the right speed.
