I could reproduce such behaviour on the U3 board, but only with u-boot which sets the MPLL clock frequency (fout_mpll) to 880 MHz, rather than 800 MHz, which was the case in my original environment. All fout_mpll child clocks have then different frequency values in both cases. It's a bit strange though, because frequencies of all the audio subsystem clocks seem to be same anyway:
I'm using the standard uboot from hardkernel.
# cat /sys/kernel/debug/clk/clk_summary
This command makes the kernel totally hang, weird.
# speaker-test -c 2 -t wav -l 2 -p 1024
This plays back fine.
Could it be a problem with the samsung-i2s driver, not correctly flushing at the right times? Or do you think the problem is more likely to be clock-related?
