1.Check if you are using autoCTS or SWCTS by putting a printk in
hdmi_acr_mode function in Linux_lsp\sound\soc\davinci\davinci-hdmi.c
2. Check HDMI i2s_mclk is 128 * Fsampling in both 1 GHZ and 1.2 Ghz case.
You can get the i2s_mclk from
mount -t debugfs debugfs /sys/kernel/debug
cd /sys/kernel/debug/clock/
3.DVRRDK has a pll_print utility .Pls run the utility and share the dumps.I am attaching the utility (remove .txt extension) but may not run on target due to toolchain diff.It is better you rebuild and run the utlity on target.

Pls share pll print for both 1 Ghz and 1.2 Ghz case.
