I find the following :

HDMI Audio sampling rate support is based on the Video resolution in use.

how to understand this sentence?

what is the relation between Video resolution and Audio sampling rate??

Hello,

Typically the audio sample rate would not be controlled by the video. Where did you find that statement?

OK, thanks. I will move this question to the Linux forum so that the PSP team will see it and respond.
